ABSTRACT
Background: Acute myocarditis corresponds to an acute inflammation of the myocardium whose origin is most often viral. Several viruses can be incriminated to note the parvovirus B19, the virus herpes of the group 6 and to a lesser degree the virus of the hepatitis C (VHC) [18,19]. Since 2019 and with the discovery of SARS COV2 some cases of myocarditis associated with covid have been noted, this last association is rare and is present in only 5% of cases [8]. The diagnosis of myocarditis is sometimes difficult and can lead to confusion with acute coronary syndrome, especially in cases of ST-segment elevation on the EKG, hence the interest of magnetic resonance imaging, which has made it possible in recent years to reduce the rate of unnecessary coronary angiography, especially in the case of young subjects with no cardiovascular risk factors. in this context we report the case of a 33 year old patient with no cardiovascular risk factors and no medical or surgical antecedents who was admitted to the emergency department for the management of acute chest pain related to acute post-covid myocarditis, the patient was initially admitted to the cardiology intensive care unit where he was put in condition and under analgesic treatment and under therapeutic protocal of covid 19 and under anticoagulation based on low molecular weight heparin at preventive dose with a good clinical evolution he was transferred thereafter to the clinical cardiology then declared outgoing under treatment of covid 19 with an appointment of control in 1 month.
ABSTRACT
COVID-19, caused by Severe Acute Respiratory Syndrome CoV-2 (SARS CoV-2), has become a global burden. The naive era of infection prompted early dependence on case reports of insufficient data and conceptual elucidation to explain and anticipate the effect on cardiovascular diseases. Many COVID-19-infected and vaccinated individuals have reported an increased incidence of cardiovascular disorders, leading to higher morbidity and mortality rates. Sometimes COVID can also manifest as a severe coronary artery disease or myocarditis in those with no background in cardiovascular diseases or those with cardiovascular risk factors, which are often misunderstood as a primary cardiovascular disorder. COVID-induced cardiovascular complications like DVT, VTE, MI, and long COVID have been the crux of the matter. To combat the SARS-CoV-2 disease, several countries took the lead in developing COVID-19 vaccines, but only a few were effective against coronavirus, which created a ray of hope in curbing COVID-19 disease. As the thumb rule says, any substance that is foreign to the body, including vaccines, has flaws seen in the forms of adverse effects/adverse events, which has created a great reluctance towards accepting COVID vaccine in society. Despite all this, it is proven that vaccines are effective in managing the COVID-19 situation worldwide, underlining the Darwinian notion.Copyright © 2023 are reserved by International Journal of Pharmaceutical Sciences and Research.
ABSTRACT
Objectives: The aim of this study is to evaluate the effect of the COVID-19 pandemic on myocardial perfusion scans (MPS) during the COVID-19 pandemic period. Method(s): We respectively reviewed single photon emission computed tomography myocardial perfusion scans (SPECT-MPS) performed between June and September 2020 during the COVID-19 pandemic at the Nuclear Medicine Research Center at Mashhad University of Medical Sciences. The findings of stress SPECT-MPS studies acquired in the corresponding months of 2019 were also evaluated for direct comparison. Result(s): In COVID-19 pandemic compared to period prior to the pandemic, no difference was observed in terms of age range of patients under study or their cardiovascular risk factors, except smoking which underwent a significant increase during the COVID-19 pandemic ( 19% vs. 13% , p = 0.009). While the number of patients with non-angina (19% vs. 31%, p = 0.000) or typical (11% vs. 19%, p = 0.000) chest pain significantly decreased during the COVID-19 pandemic, atypical (42% vs. 25%, p = 0.000) chest pain cases showed an increasing number. By considering pretest probability of the patients (high, intermediate and low/very low), during the COVID-19 period, cases of high pretest probability decreased (6% vs. 18%, p = 0.000) and intermediate pretest probability patients also increased (64% vs. 55%, p = 0.005) while low/very low pretest probability cases showed no changes between the two periods. All types of MPS stress tests in the COVID-19 period were pharmacological compared to exercise stress test. No statistically significant difference on the myocardial ischemia or cardiomyopathy between patients between the two periods was observed. Summed stress score (SSS) and summed rest score (SRS) was similar over the two periods,while summed difference score (SDS) significantly increased over the course of COVID-19, confirming a non- increasing pattern of myocardial ischemia. Conclusion(s): Previous research underscores the fact that the number of stress SPECT-MPS studies was significantly reduced during the COVID-19 pandemic compared to the corresponding months prior to the pandemic [1, 2]. Our study concluded that all types of MPS stress tests in the COVID-19 period were pharmacological. This is due to the fact that all related recommendations published in the literature [3] highlighted the avoidance of exercise stress tests during the COVID-19 pandemic to reduce the risk of droplet exposure. During the COVID-19 pandemic, patients in two ends of the spectrum (e.g., non-angina & typical chest pain) were referred less for MPS. However, patients in the middle of the spectrum (e.g., atypical chest pain) underwentMPS less frequently. Myocardial ischemia and cardiomyopathy were not decreased or increased in patients over the COVID-19 period.
ABSTRACT
Comprehensive medication management (CMM) is increasingly provided by health care teams through telehealth or hybrid modalities. The purpose of this scoping literature review was to assess the published literature and examine the economic, clinical, and humanistic outcomes of CMM services provided by pharmacists via telehealth or hybrid modalities. This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. Randomized controlled trials (RCTs) and observational studies were included if they: reported on economic, clinical, or humanistic outcomes;were conducted via telehealth or hybrid modalities;included a pharmacist on their interprofessional team;and evaluated CMM services. The search was conducted between January 1, 2000, and September 28, 2021. The search strategy was adapted for use in Medline (PubMed);Embase;Cochrane;Cumulative Index to Nursing and Allied Health Literature;PsychINFO;International Pharmaceutical s;Scopus;and grey literature. Four reviewers extracted data using a screening tool developed for this study and reviewed for risk of bias. Authors screened 3500 articles, from which 11 studies met the inclusion criteria (9 observational studies, 2 RCTs). In seven studies, clinical outcomes improved with telehealth CMM interventions compared to either usual care, face-to-face CMM, or educational controls, as shown by the statistically significant changes in chronic disease clinical outcomes. Two studies evaluated and found increased patient and provider satisfaction. One study described a source of revenue for a telehealth CMM service. Overall, study results indicate that telehealth CMM services, in select cases, may be associated with improved clinical outcomes, but the methods of the included studies were not homogenous enough to conclude that telehealth or hybrid modalities were superior to in-person CMM. To understand the full impact on the Quadruple Aim, additional research is needed to investigate the financial outcomes of CMM conducted using telehealth or hybrid technologies.Copyright © 2022 Pharmacotherapy Publications, Inc.
ABSTRACT
Aim - the discutability of existing scientific publications prompted a retrospective analysis of COVID-19 risk factors among the working population using the example of Russian Railways. Material and methods. Based on the archival documentation of medical institutions of Russian Railways, an analysis of the incidence of employees of the holding was carried out. Data from 2452 cases were analysed, for which full medical documentation was available. The comparison group randomly included 2911 workers who did not have COVID-19, comparable in sex, age, and area of residence. Results. Significant factors of difference between the groups of patients and those who were not ill were: sex, the presence of influenza vaccination, smoking and established diabetes mellitus. There was a trend towards an association of COVID-19 incidence and the presence of cardiovascular disease. In the comparison group, unlike the group of COVID-19 cases, there are 23% more persons who were vaccinated against influenza. In the group of patients with diabetes mellitus was found 3 times more often than in the group of non-patients. In both groups, the incidence rates of cardiovascular disease did not differ. However, as the severity of the disease increased, there was a tendency to increase the incidence of cardiovascular diseases. Meanwhile, the presence of other cardiovascular risk factors (male sex, smoking, diabetes mellitus, obesity) was significantly associated with a higher incidence in the disease group compared to non-patients. Multifactorial analysis also revealed other significant combinations of risk factors with COVID-19 risk: lack of influenza vaccination and the presence of diabetes mellitus;lack of vaccination, smoking and the presence of diabetes mellitus. Conclusion. For the working population, male sex and diabetes may be a significant risk factor for developing COVID-19. Influenza vaccination should be considered as a factor in anti- COVID-19 protection. Cardiovascular diseas e and smoking may serve as additional risk factors.Copyright © 2021 Infectious Diseases: News, Opinions, Training. All rights reserved.
ABSTRACT
It is now widely known that COVID-19 can also cause various extrapulmonary manifestations. Possible mechanisms of cardiovascular damage include direct myocardial damage due to hypercoagulability caused by systemic inflammation, which may also lead to destabilisation of coronary plaques. We present a case of a 30-year-old young man following asymptomatic COVID-19 infection, who was admitted to the emergency room of the Grande Ospedale Metropolitano di Reggio Calabria, Italy, with typical chest pain. The patient had no cardiovascular disease, cardiovascular risk factors including no family history of cardiovascular disease. Urgent coronary angiography showed critical stenosis of the middle-proximal portion of the left anterior descending artery (80%) with ulcerated plaque appearance. Regardless of cardiovascular risk factors, our case report emphasises the need to determine COVID-19 status in all patients with acute myocardial infarction during this pandemic.Copyright © 2023, CKS.
ABSTRACT
Background: Although Brain Natriuretic Peptide (BNP) provides strong prognostic information of an unfavorable outcome in patients with acute heart failure (AHF), there is little information of its relevance as a biomarker for outcomes in COVID-19 and its complications Purpose: To evaluate the association of increased BNP levels with complications and in-hospital mortality in a cohort of hospitalized COVID-19 patients. Method(s): The study included COVID-19 patients with data on BNP levels included in the ISACS COVID-19 registry. The population was categorized according to the presence of peak BNP levels >=100 pg/mL during hospitalization. Primary outcomes included in-hospital mortality, AHF or acute respiratory failure (ARF, defined as PiO2/FiO2<300 mmHg or need for mechanical ventilation). Calculations were conducted using age and sex-adjusted multivariable logistic regression analyses. Results were also stratified according to presence or absence of cardiovascular disease (CVD) history. Differences between subgroups were verified for statistical significance using test for interaction. Result(s): Of the 1152 patients included in the study, 615 (53.4%) had elevated BNP levels. These subjects were older (69.9+/-13.8 vs 59.1+/-16.8, p-value<0.001), had higher rates of cardiovascular risk factors (82.9% vs 57.7%, p-value<0.001) and presented more frequently with a prior history of CVD (either ischemic heart disease, cerebrovascular disease, venous thromboembolism, atrial fibrillation or a history of revascularization) (50.1% vs 27.5%, p-value<0.001). No sex differences were observed. When considering outcomes, BNP levels >=100 pg/mL were associated with increased rates of in-hospital mortality (32.9% vs 4.9%, p-value<0.001), even after adjustment for demographic characteristics (OR: 7.35;95% CI: 4.75-11.40;p-value<0.001). High BNP levels were also strongly associated with an increased risk of AHF (OR 19.9;95% CI 8.6-45.9;pvalue< 0.001), a correlation that persisted both in patients with and without a prior CVD history (p for interaction=0.29). Of note, patients with elevated BNP also had a higher likelihood of developing ARF (OR 2.7;95% CI 2.1- 3.6;p-value<0.001), even in absence of AHF (OR 3.00;95% CI 2.20-4.1;p-value<0.001). Conclusion(s): In COVID-19, blood BNP level not only appears to be predictor of in-hospital mortality and AHF but was also independently associated with an increased risk of ARF. This finding supports the routine use of BNP in all patients admitted to hospital for COVID-19, regardless of a prior history of CVD.
ABSTRACT
Background: Patients with cancer represent a uniquely vulnerable population not only with higher susceptibility to COVID-19 but also at increased risk for death. However, detailed information on causes of death and the contribution of pre-existing health conditions to death yet is missing. Purpose(s): This study focuses on the implications of COVID-19 in the cardiovascular health of patients with cancer by assessing the relation between cancer and de novo acute heart failure (AHF) with in-hospital mortality. Method(s): The initial population consisted of 3968 patients included in the ISACS COVID-19 registry between March 2020 and February 2022. Of these, 546 patients with chronic HF were excluded, leaving a final population of 3422. Patients were divided in two groups according to the presence or absence of a cancer diagnosis at the time of hospitalization for COVID- 19. Primary outcomes were incidence of in-hospital mortality or AHF during hospitalization. Association between cancer and outcomes was estimated using multivariable logistic regression analyses. Subsidiary analysis was conducted to evaluate differences between patients with prior vs active cancer. Result(s): Of the 3422 patients included in the study, 468 patients had cancer (8.2% active, 5.5% past cancer). Cancer patients were older (68.9+/-13.4 vs 63.3+/-15.6, p-value <0.001) and more likely to be female (50.4% vs 39.1%, p-value <0.001). They presented more frequently with a history of chronic obstructive pulmonary disease (12.3% vs 7.6%, p-value = 0.001). When considering outcomes, cancer patients had a significantly higher incidence of in-hospital mortality (27.7% vs 19.2%;p-value <0.001). This despite the presence of a numerically higher mean PiO2/FiO2 (281+/-108.8 vs 267.05+/-122.5, p-value = 0.11) on admission and a lower rate of X-ray findings of interstitial pneumonia (60% vs 70.5%, p-value <0.001) than their non-oncological counterparts, as well as similar use of mechanical ventilation (30.6% vs 35.0%, p value=0.14). The association between cancer and death persisted when adjusting for demographic, laboratory findings and in-hospital treatment (OR: 1.46;95% CI: 1.11-1.94;p value=0.01). Cancer patients also had higher rates of AHF (9.6% vs 4.7%, p-value <0.001) during hospitalization. This association was independent from presence of cardiovascular risk factors or comorbidities (OR: 1.61;95% CI: 1.07-2.43;p value=0.02). When restricting the analysis to the cancer population, AHF appeared to be significantly associated with death (OR: 2.41;95% CI 1.18- 4.95;p-value = 0.01), but this correlation persisted only in patients affected by active cancer in age and sex adjusted analyses (OR: 4.27;95% CI: 1.51-12.07;p value=0.01 vs 1.20;95% CI: 0.38-3.76;p-value = 0.75). Conclusion(s): The incidence of AHF in cancer patients with COVID-19 is high. Patients with active cancer are also at high risk for mortality. This has implications for cardiac monitoring and chemotherapy administration during COVID-19.
ABSTRACT
Introduction: It is estimated that 15% of patients with AS have concomitant cardiac amyloidosis (CA). Left ventricular (LV) longitudinal strain (LS) pattern with relative apical sparing (RELAPS>1), shown as bright red in the apical segments on the polar map, has been strongly associated with CA. Its presence and its significance in AS is yet to be determined. Purpose(s): To determine the prevalence of the RELAPS>1 pattern in patients with severe AS with and without concomitant CA, and to analyze the echocardiographic phenotype associated with this strain pattern and its prognostic value. Method(s): Patients with severe symptomatic AS undergoing TAVI were prospectively and consecutively included between Jan-19 and Dec-20. Pre-procedure, a complete echocardiogram was performed that included deformation parameters using Speckle-Tracking. Strain derived Indices accepted for CA screening were calculated: RELAPS: Relative apical LS (average apical LS/average basal+mid LS);SAB: (apical-septal/basal-septal LS);EFSR: (LVEF/GLS). After TAVI, a 99Tc-PYP scintigraphy and a proteinogram were performed to screen for CA. Result(s): 324 patients were included. The mean age was 81 yo, 52% women. Strain analysis could be performed in 243 patients due to acoustic window and covid19 pandemic restrictions. Among those, 111 (46%) presented relative apical sparing (RELAPS>1). There were no differences in clinical characteristics between patients with RELAPS <1 and >1: Similar age, sex, cardiovascular risk factors and funcional class, renal function or NT-proBNP. Among patients with RELAPS>1 there was more frecuently CA with uptake grade 2 and 3 on scintigraphy (15% vs. 4.5%, P=0.006) (Figure 1). RELAPS>1 group showed greater LV hypertrophic remodeling: Thicker myocardial wall with smaller ventricular cavity, especially concentric hypertrophy;LVEF and GLS was similar, however, MAPSE and myocardial contraction fraction (MCF) were worse in RELAPS >1 group, and EFSR was significantly higher (4.2 vs 3.9, p=0.002). RELAPS >1 group had smaller aortic valve area (AVA: 0.6 vs 0.7 cm2, p=0.045), but similar transvalvular gradients due to lower stroke volume. It had larger atria and less left atrial (LA) fractional emptying, as well as higher prevalence of atrial fibrillation (AF: 41% vs 27%, p=0.03). Right ventricle (RV) size were similar, however, RV function was worse in RELAPS >1 group (TAPSE: 19 vs 21 mm, p=0.003;free Wall LS: -24 vs -27%, p=0.008). There was no difference in all-cause mortality at 1 year of follow-up between groups (6.4% vs. 6.3%, p=1). Figure 2 represents the morphological characteristics according to the LS phenotype. Conclusion(s): In severe AS, RELAPS >1 is present in almost half of the patients. It is associated with worse cardiac remodeling, as well as higher prevalence of AF. However, it wasn't associated with higher mortality at 1 year. 1 in 7 patients with AS and RELAPS >1 have concomitant ATTR CA grade 2/3.
ABSTRACT
Background: Patients with COVID-19 have an increased risk of cardiovascular adverse events during the acute phase. However, the long-term cardiovascular outcomes are unknown. Objective(s): We aimed to determine the long-term effects of COVID-19 in the cardiovascular system. Method(s): This is a multicenter, observational, retrospective registry conducted at 17 centers in Spain and Italy. Consecutive patients older than 18 years who underwent a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV2 in the participating institutions were included. Patients were classified into two groups, according to the results of the RT-PCR: COVID-19 positive or negative. The primary outcome was cardiovascular (CV) death at 1-year. The secondary outcomes included acute myocardial infarction, stroke, heart failure hospitalization, pulmonary embolism, and serious cardiac arrhythmias at 1-year. Outcomes were compared between the two groups. An independent clinical event committee adjudicated events. Result(s): A total of 4427 patients were included, 3578 (80.8%) patients with COVID-19 and 849 (19.2%) without COVID-19. COVID-19 patients were older, had a higher rate of classical cardiovascular risk factors, except for active smoking, and had fewer comorbidities. At a median time of 13.5 (IQR 11.8-15.8) months, after an adjustment by baseline characteristics, there was no difference in CV death (1.4% vs. 1.1%;HR 1.03 [0.49-2.18];p=0.941) between patients with COVID-19 and without. However, COVID- 19 patients experienced higher rate of venous thromboembolism (VTE) (3.9% vs. 0.6%, HR 6.11 [2.46-15.16];p=0.001), major bleeding (2.9% vs. 0.5%, HR 5.38 [1.95-14.84];p=0.001), and serious cardiac arrhythmias (2.6% vs. 0.9%, HR 2.25 [1.07-4.73];p=0.033). During follow-up, between discharge and end of follow-up, COVID-19 patients did not experience a higher risk of adverse cardiovascular outcomes (composite of CV death, any MI, ischemic stroke, systemic arterial thrombosis, VTE, heart failure hospitalization, or any serious arrhythmia) compared to patients without (HR 0.80;[0.53-1.21];p=0.298). Conclusion(s): At 1-year follow-up, COVID-19 was not associated with an increased risk of cardiovascular death but with a higher risk of VTE events, major bleeding, and serious cardiac arrhythmias. COVID-19 was not associated with a higher risk of adverse cardiovascular events during follow-up.
ABSTRACT
Calcium levels in the Coronary Artery are an indicative marker of the presence and extent of atherosclerosis. This serves as an additional prognostic indicator in addition to traditional risk factors. Moreover, the coronary calcium test is associated with a descriptor known as the calcium score or calcium score (Cs), which is primarily useful for stratifying the risk of asymptomatic patients, while for patients with acute or chronic chest pain, coronary axial computed tomography is generally required. A retrospective analysis of data was conducted in the radiology department of King Salman Specialist Hospital in Hail City, the kingdom of Saudi Arabia, between January and May 2022. A total of 40 patients were randomly selected, 25 males and 15 females. The study included all patients with or suspected of having a calcium deposit who underwent a CT scan using the Siemens SOMATOM definition MDC scan. Patients underwent a scan with the preparations and laboratory tests required for their coronary artery calcium scores. In this study, males were more likely to be affected by calcium deposits (64%), whereas females were 36%. Approximately 50 percent of the study populations were found to be normal (no identifiable calcium deposits) and 37.5% to have moderate calcium deposits. There is a significant association between CACS and moderate CVD risks based on age and gender in this study. Better control of cardiovascular system (CVS) risks is recommended in all primary care centers in the Kingdom of Saudi Arabia (KSA).Copyright © 2022 International Journal of Pharmaceutical Research and Allied Sciences.

ABSTRACT
Background: COVID-19 infection has been shown to have an adverse impact on the cardiovascular system. Cardiac injury, as indicated by elevated cardiac troponin and NT-proBNP levels have been confirmed in COVID-19 cases. There is still ambivalent data on the effect of left ventricular function. Cases of left ventricular impairment, persistent hypotension, acute myopericarditis, myocarditis, arrhythmia and heart failure have been reported in the short term, but there is a significant lacuna when it comes to medium and long-term follow-up of subjects previously infected with COVID-19. Purpose(s): To assess any residual myocardial and autonomic injury in subjects previously infected with COVID-19 at a median follow-up of 5 months. Method(s): A case-control study was performed. Cases were randomly selected subjects who were previously diagnosed with COVID-19 infection following nasopharyngeal swabbing. Controls were subjects who had not been found to be infected with COVID-19 following swabbing and were negative for COVID-19 IgG antibodies. All participants were submitted a standardised questionnaire regarding past medical history. Blood investigations were taken including NT-proBNP and troponin I levels. In addition, all participants underwent 24-hour ambulatory blood pressure monitoring (ABPM) and 24-hour ECG monitoring. The latter was used to assess both for underlying arrhythmias as well as heart rate variability (HRV), a measure of autonomic regulation of the heart. All data was analysed using SPSS version 23.0. Result(s): The study comprised 259 subjects, whereby cases included 174 participants while 75 subjects were age- and gender-matched controls. The study cohort was relatively young with a mean age of 46.1+/-13.8 years. The median follow-up was of approximately 5 months (median 173.5 days, IQR 129-193.25 days). There was no statistically significant difference between cases and controls with regards cardiovascular risk factors and underlying medical conditions. Likewise, there was no difference in blood investigations, including troponin I and NT-proBNP levels at 5-months followup. No difference was noted between the two groups in both awake and asleep blood pressure (BP) readings, as well as dipping BP status. No significant arrhythmias were noted in both groups on 24-hour ECG monitoring. However, when assessing for heart rate variability, it was shown that subjects who had been previously infected with COVID-19 exhibited lower root-mean square differences of successive R-R intervals (RMSSD), p=0.028. This indicates poor vagus nerve-mediated autonomic control of the heart. Conclusion(s): Subjects previously infected with COVID-19 exhibited lower HRV as exhibited by low RMSSD as compared to controls. Reduced HRV is a known biomarker for mortality and sudden death in cardiac disease. The possible long-term implications of reduced HRV in subjects previously infected with COVID-19 merits further investigation.
ABSTRACT
Background: Cardiovascular complications are rapidly emerging as a major threat in COVID-19 infection. Nonetheless, the mechanisms underlying the disproportionate effect of SARS-CoV-2 infection on patients with cardiovascular comorbidities remain incompletely understood. Purpose(s): To assess whether COVID-19 infection has an adverse clinical outcome at medium-term follow-up. Method(s): A case-control study was performed. Cases were subjects who were diagnosed with COVID-19 infection following nasopharyhngeal swabbing. Controls were age- and gender-matched subjects who were not found to be infected with COVID-19 following swabbing and were negative on testing for COVID-19 IgG antibodies. All participants were submitted a standardised questionnaire regarding past medical history. Baseline blood investigations were taken including N-terminal pro-B-type natriuretic peptide (NT-proBNP) and troponin levels. High-sensitivity C-reactive protein (hsCRP) was taken as marker of inflammation and von Willebrand factor (vWF) was taken as marker of endothelial dysfunction. Result(s): 270 subjects were recruited, comprising 174 cases and 96 controls. Of the latter, 21 were found to be COVID-19 IgG positive and were excluded from the analysis. Hence, the study cohort comprised 174 cases and 75 controls. The mean age of the participants was 46.1+/-13.8 years. The median follow-up was of 173.5 days (IQR 129-193.25 days). There was no statistically significant difference in the baseline demographics between cases and controls with regards age, gender as well as cardiovascular risk factors and underlying medical conditions. Regarding symptomatology at follow-up, there was a statistically significant difference between the groups in deterioration in general condition (p<0.001), shortness of breath (SOB) (p=0.008), fatigue (p=0.044), arthralgia (p<0.001), abnormal taste (p<0.001) and anosmia (p<0.001), all being more frequent in subjects with prior COVID-19 infection. At follow-up, the blood investigations showed that only hsCRP was statistically significantly higher in the cases as compared to the controls (p=0.03, Figure 1). Correlation analysis consequently revealed a negative correlation in both troponin (p=0.013, r=-0.19) and vWF levels (p=0.026, r=-0.169) with time. Finally, the association between the cases experiencing dyspnoea and the blood investigations at follow-up was assessed. Multivariate analysis revealed that COVID-19 positive cases experiencing dyspnoea have significantly higher white cell count (WCC) (OR 1.22, 95% CI 1.02-1.46, p=0.029) and troponin levels (OR 1.15, 95% CI 1.02-1.29, p=0.015) and lower haemoglobin levels at follow-up (OR 0.66, 95% CI 0.5-0.86, p<0.002), Figure 2. Conclusion(s): Patients previously infected with COVID-19 have persistent symptomatology at medium-term follow-up. The role of troponin, together with markers of inflammation and endothelial dysfunction at long-term follow-up merit further investigation. (Figure Presented) .
ABSTRACT
Background: Coronavirus disease (COVID)-19 is an entity characterized by a cytokine storm and profound endotheliitis. Although several reports have pointed to the presence of endothelial dysfunction in the acute phase, data is accumulating regarding a possible prolonged adverse effect of COVID-19 on endothelial function. Purpose(s): This systematic review and meta-analysis aims to evaluate the degree of endothelial impairment, assessed by flow-mediated dilation (FMD) of the brachial artery, in individuals recovering from COVID-19. Method(s): We conducted a systematic literature search for studies assessing FMD between in patients post-COVID-19 and controls. Exclusion criteria consisted of the absence of a control group, measurement of FMD only during the acute phase of the disease, and not reporting FMD in % change. Effect sizes were pooled via random-effect model and the results are expressed as uncorrected standardized mean difference (SMD), using the Cohen's d as the effect size metric, with 95% confidence intervals (CI). Between-study heterogeneity was assessed through the calculation of I2. Subgroup analysis according to follow-up duration and the presence of cardiovascular risk factor-matched controls was also carried out. Result(s): Database search identified 51 studies. Following the application of the exclusion criteria, 7 studies were included in the meta-analysis (post-COVID-19: 342 subjects, Control: 273 subjects). Compared to controls, patients post-COVID-19 had significantly lower FMD% values (SMD: -1.06, 95% CI: -1.74 to -0.38, p<0.01, I2: 86%) (Figure 1). Results remained unaffected after exclusion of any single study using the leave-oneout method. Subgroup analysis revealed no significant differences in FMD between post-COVID-19 patients and controls according to follow-up duration or the presence of cardiovascular risk factor-matched control group. Conclusion(s): Flow-mediated dilation of the brachial artery, indicative of endothelial dysfunction, was significantly reduced in post-COVID-19 subjects compared to non-infected controls. This finding may be an alarming sign towards a higher risk of incident cardiovascular events. (Figure Presented) .
ABSTRACT
Introduction: STEMI is one of the cardiac emergencies whose management has been mostly challenged by the COVID-19 pandemic. Patients presenting with the "lethal combo" of STEMI and concomitant SARS-CoV- 2 infection have faced dramatic issues related to need for self-isolation, systemic inflammation with multi-organ disease, and difficulties to obtain timely diagnosis and treatment. Method(s):We performed a systematic search of three electronic databases from February 1st 2020 to January 31st 2022. We included all studies reporting crude rates of in-hospital outcomes of STEMI patients with concomitant COVID-19. Result(s): A total of 9 observational studies were identified, mainly conducted during the first wave of the pandemic. STEMI patients with COVID -19 were more likely Afro-American and displayed higher rates of hypertension and diabetes with lower smoking prevalence. Associated comorbidities, including coronary artery disease, prior stroke and chronic kidney disease were also more common in those with SARS-CoV-2 infection. At coronary angiography, a higher thrombus burden in COVID-19 positive STEMI patients was highlighted, with up to 10-fold higher rates of stent thrombosis and greater need for glycoprotein IIb/IIa inhibitors and aspiration thrombectomy;this was not always associated with prolonged times from symptom onset to hospital admission and door-to-balloon. COVID-19 positive STEMI patients were less likely to receive coronary angiography and primary PCI, and more likely to be treated with fibrinolytics only. At the same time, patients with Covid-19 were more prone to present MINOCA. In-hospital mortality ranged from 15% to 40%, with consistent variability across different studies and subjects who tested positive for SARS-CoV- 2 did also present higher rates of cardiogenic shock, cardiac arrest, prolonged ICU stay, mechanical ventilation, major bleeding, and stroke. Conclusion(s): The coexistence of STEMI and COVID-19 was associated with increased in-hospital mortality and poor short-term prognosis. This was not entirely attributable to logistic issues determining delayed coronary revascularization, since patients' specific clinical and angiographic characteristics, including higher burden of cardiovascular risk factors and greater coronary thrombogenicity might have substantially contributed to this trend.

ABSTRACT
OBJECTIVE: To describe the first 9 months of a newly established computed tomography coronary angiogram (CTCA) over the period of the COVID-19 pandemic. METHODS: A retrospective analysis of the first 9 months of a CT-CA program. DESIGN: Data were collected for the period of June 2020 to March 2021. Information reviewed included demographics, risk factors, renal function, technical factors and outcomes including Calcium Score and Coronary Artery Disease Reporting and Data System (CAD-RADS). SETTING: A single Rural Referral Hospital in regional New South Wales. PARTICIPANTS: Ninety-six CTCAs were reviewed. Ages ranged from 29 to 81 years. 37 (39%) male, 59 (61%) female. 15 (15.6%) identified as Aboriginal and/or Torres Strait Islander. MAIN OBJECTIVE OUTCOMES: CTCA is a viable alternative to invasive coronary angiogram in appropriate populations for regional areas. RESULTS: Eighty-eight (91.6%) were considered technically satisfactory. Mean heart rate was 57 beats per minute with a range of 108. Cardiovascular risk factors included hypertension, dyslipidemia, smoking status, family history and diabetes mellitus. Of patients with CAD-RADS scores 3 or 4 who underwent subsequent invasive coronary angiogram (ICA), 80% were determined to have operator-defined significant stenosis. Significant cardiac and non-cardiac findings were extensive. CONCLUSIONS: CTCA is a safe and efficacious imaging modality for low- to moderate-risk chest pain patients. There was acceptable diagnostic accuracy and the investigation was safe.
ABSTRACT
Introduction: In December 2019, a novel Coronavirus disease 2019 (COVID-19) was discovered and spread rapidly worldwide. The virus spared no country in its contagiousness. The most common clinical manifestations are respiratory symptoms;but COVID-19 may induce arrhythmias, myocardial infarction, heart failure, and other cardiovascular diseases due to the systemic inflammatory response coupled with localized vascular inflammation. The study aims to provide knowledge about the clinical profile, cardiovascular complications, and clinical outcomes among adult COVID-19 patients admitted to a tertiary hospital. Method(s): This study is a single-centered cross-sectional retrospective study of hospitalized adult COVID-19 patients between March 2020 to May 2022. COVID-19 confirmed patients who met the inclusion criteria with clinical data upon hospitalization are followed up for occurrence of critical illness. The study's primary outcome is determining the demographic profile and clinical course of COVID-19 infection regarding cardiovascular signs and symptoms. Data were retrieved from electronic health records. All outcomes were obtained with standardized data collection forms, and clinical severity was defined based on the National Institute of Health guidelines. Result(s): A total of 1341 hospitalized adult COVID-19 patients were admitted with a mean age of 50.41+/-15.92 years. More males than females account for 60.2% of the total number of patients. Hypertension is the most common comorbidity among COVID-19 patients, comprising 44% of cases, followed by diabetes at 31.9% and dyslipidemia at 11.4%. About 5.4% had coronary artery disease, followed by heart disease 6 (3.6%) and arrhythmia (0.6%). Most COVID-19 patients were smokers 12% and alcoholic beverage drinkers (11.4%). A univariate analysis associated with mortality showed diabetes mellitus (odds ratio 2.7, p = 0.029) and hypertension (odds ratio 3.4, p = 0.11). In the multiple logistic regression analysis, factors' age (OR 1.095, estimate coefficient 0.091, standard error 0.028, p-value <0.05) and admission duration (OR 0.906, estimate coefficient -0.099, standard error 0.028, p-value <0.05) were significantly associated with mortality. Based on the fitted model, older people are more likely to be deceased than younger people. The log odds for mortality increase by 0.091 units for each year. During hospital admission, 24.43% of patients developed acute COVID-19 infection, with an in-hospital casefatality rate of 13.89%. During hospital stay, COVID-19 patients had a significant QTc (.43 +/- 0.04, p'0.001). Patients admitted to Non-ICU had lower QTc (.44 +/- 0.045) compared to ICU patients (.45 +/- .05). Conclusion(s): Myocardial injury and significant cardiovascular risk factors increased mortality among critically-ill COVID-19 patients. Hence, aside from risk factor modification, emphasis on cardiovascular protection should also be considered during treatment for COVID-19.
ABSTRACT
Introduction: Few studies have evaluated the impact of COVID-19 on interstitial lung diseases (ILDs). Our aim was to compare outcomes in patients with fibrotic-ILDs (F-ILDs) and non-fibrotic-ILDs (NF-ILDs) after COVID-19. Method(s): We reviewed patients with ILD followed in a Portuguese university hospital. Patients' features and COVID- 19 outcomes were compared between F-ILDs and NF-ILDs groups. We used Kaplan-Meyer analysis to estimate overall survival (OS) and cox-proportional-hazards regression models to identify factors associated with OS. Result(s): A total of 103 patients (49.5% were male;mean age of 61.5+/-14.5 years) were included. The most prevalent ILDs were sarcoidosis (26.2%), HP (14.6%), CTD-ILD (14.6%), OP (8.7%), IPF (7.8%) and unclassifiable idiopathic interstitial pneumonia (7.8%). 47.6% of patients had F-ILD, and they had a higher prevalence of dyslipidemia (p=0.006) and immunosuppressive therapy (p<.001). Regarding the severity of COVID-19, 64.7% had mild, 11.7% moderate and 24.3% severe disease. There was a higher proportion of severe disease among F-ILDs patients (34.7% vs 14.8%, p=0.019). Post-COVID-19 mortality (median follow-up of 44 weeks) was significantly higher in FILD than NF-ILD cases (30.6% vs 5.6%, p=0.001). The median OS was significantly lower for patients who had severe disease (18.0 vs 45.5 weeks;p<.001) and F-ILD (41 vs 45 weeks;p=0.001). According to multivariate analysis, F-ILD (HR:4.00, p=0.042) and severe disease (HR:6.98, p=0.008) were the factors associated with worse OS. Concluding: In our analysis, COVID-19 was associated with worse outcomes in patients with F-ILDs and severe COVID-19, regardless of cardiovascular risk factors.
ABSTRACT
Microparticles (MPs) are vesicles of less than 1 mum in diameter (submicron vesicles) shed from plasma membranes to cell activation, injury, and apoptosis response. They consisted of membrane proteins and cytosolic material from the cell they originated. These vesicles are vital mediators of pathological and physiological cellular processes. Polycystic ovary syndrome (PCOS) is a regular endocrine, menstrual and metabolic condition that affects 10-15% of females in their reproductive period. Numerous researches have described the association between low-grade chronic inflammation and PCOS;however, the relation is not well understood. Chronic low-grade inflammation is reflected as a risk factor for cardiovascular disease, atherosclerosis, and endothelial dysfunction, and it is linked to abdominal obesity and insulin resistance (IR). MPs may be useful biomarkers for the early detection of cardiovascular disease and thrombosis in PCOS patients. In March 2020, the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) became pandemic, wreaking havoc on healthcare systems worldwide and the global economy. Obesity, diabetes, and cardiovascular disease have all been linked to COVID-19 increased risk of infection. PCOS patients have recently been identified as an underserved and potentially high-risk demographic for COVID-19 problems. This article tried to review and present recent studies that explored the role of microparticles in polycystic ovarian syndrome.Copyright © 2022 International Journal of Pharmaceutical Research and Allied Sciences.

ABSTRACT
Background Prior Coronavirus Disease 2019 (COVID-19) infection has been associated with endothelial injury and coronary microvascular dysfunction (CMD). We aimed to assess if there was an association between SARS-CoV-2 variants and the magnitude of CMD. Methods A prospective cohort of consecutive patients undergoing clinically indicated positron emission tomography (PET) myocardial perfusion imaging were included. Cases that had a polymerase chain reaction (PCR)-confirmed prior COVID-19 infection matched 1:3 on clinical and cardiovascular risk factors to controls with no prior COVID-19. Variants were estimated by the temporal prevalence at time of diagnosis based national reporting. Myocardial flow reserve (MFR) was determined by PET and CMD was defined as MFR<2. Results A total of 282 cases were matched to 869 controls;mean (+/-SD) age 65 (+/-12), 48% female. Most patients with prior COVID-19 infection were diagnosed when the Alpha/Beta variants were dominant (60.6% Alpha/Beta, 19.9% Omicron, 19.5% Delta). The highest rate of CMD was seen with patients diagnosed during the Delta dominance (56.4% Delta, 50% Omicron, 48.5% Alpha/Beta vs 27.7% controls, P for trend<0.001). Conclusion Our analysis shows the magnitude of COVID-19-associated CMD may differ based on the SARS-CoV-2 variant. [Formula presented]Copyright © 2023 American College of Cardiology Foundation
