The burden of alcohol-related cardiovascular complications in young and middle-aged adults: rising burden of atrial fibrillation and hypertensive heart disease.

BACKGROUND AND AIMS: The burden of alcohol-related complications is high and rising. However, there are notable deficiencies in comprehensive epidemiological study focusing on cardiovascular complications from alcohol, especially among young and middle-aged adults. We thus aimed to determine the burden of these conditions in young and middle-aged adults globally. METHODS AND RESULTS: We used data from the Global Burden of Disease Study 2019 and analysed the mortality and disability-adjusted life years of alcohol-associated cardiovascular complications in young and middle-aged adults. The findings were classified by sex, region, country, and Sociodemographic Index (SDI). The highest age-standardized death rates (ASDR) were observed in stroke 0.84 (95% UI 0.60-1.09), followed by alcoholic cardiomyopathy 0.57 (95% UI 0.47-0.66) per 100,000 population. The overall burden of alcohol-associated cardiovascular complications decreased globally but increased in atrial fibrillation and hypertensive heart disease. Regionally, most regions underwent a decrease in ASDR, but an increase was observed in Southeast Asia (+2.82%), Western Pacific (+1.48%), low-middle (+1.81%), and middle SDI (+0.75%) countries. Nevertheless, the ASDR and ASDALYs were highest in Europe. CONCLUSIONS: The impact of alcohol-associated atrial fibrillation and hypertensive heart disease has increased over the last decades. Regarding region, the burden in Europe and the rising burden in Asia, require immediate public health policy to lessen these cardiovascular complications from alcohol in young and middle-aged adults.

The Association and Utility of Left Ventricular End-Diastolic Pressure in Predicting the Development of and in Managing Contrast-Induced Nephropathy in Patients Undergoing Coronary Angiography.

Contrast-induced nephropathy (CIN) is a significant complication in patients undergoing coronary angiography, and its development is associated with increased morbidity and mortality. Left ventricular end-diastolic pressure (LVEDP) provides one index of left heart filling status. An elevated LVEDP can reflect volume overload or abnormal diastolic function and indicates a cardiac disorder. Data on the association between an elevated LVEDP and CIN are limited and have had conflicting results. We systematically searched the databases PubMed, Embase, and Scopus for full-text articles from database inception to May 2022. Studies were included if they evaluated the association between a high LVEDP and the incidence of CIN in patients undergoing coronary angiography. The study was registered in the PROSPERO CRD42022334070. A second search in PubMed identified randomized controlled trials using LVEDP to guide fluid administration during coronary procedures. Four studies were identified that used LVEDP to classify patients into groups to determine the association between the level and the development of CIN. In these studies, 240 patients of 2441 patients (9.8%) developed CIN. One study found no association between LVEDP levels and the development of CIN. Two studies found an increased frequency of CIN in patients with elevated levels using 2 cutoff points for LVEDP, ≥20 mm Hg and >30 mm Hg. One study found that lower LVEDP levels (5-14 mm Hg) were associated with the development of CIN. Three randomized control trials used LVDEP levels to manage fluid administration in patients undergoing coronary procedures; only one study found that the use of these levels to guide fluid administration resulted in better outcomes. In patients undergoing coronary angiography, an elevated LVEDP was not consistently associated with increased risk of CIN, and using LVEDP levels to guide fluid administration during these procedures did not always improve outcomes in comparison to other protocols. The use of LVEDP levels can help classify patients with cardiac disorders but does not necessarily provide an adequate description of the hemodynamic patterns in these patients to predict or prevent CIN in patients undergoing angiography.

Omeprazole Induced Rapid Drug Reaction with Eosinophilia, Systemic Symptoms, and Cross-Reactivity in Delayed-Type Hypersensitivity Associated with Proton-Pump Inhibitors: A Case Report and Literature Review.

Background: Omeprazole, a proton pump inhibitor (PPI), is a widely used and generally safe agent for treating acid-related gastrointestinal conditions. However, drug reaction with eosinophilia and systemic symptoms (DRESSs) syndrome has been reported. Objectives: To report a case of omeprazole-induced rapid DRESS syndrome and to review the literature. Methods: Descriptive analysis of one new case and a case series from literature review. Results: We report a case of 82-year-old woman presenting with rapid-onset of DRESS syndrome. The condition was initially suspected to be caused by antibiotic, but the definite diagnosis was eventually omeprazole-induced DRESS syndrome as suggested by the enzyme-linked immune absorbent spot (ELISpot) assay along with the clinical picture. Previous literatures regarding cases of PPI-induced DRESS syndrome were pooled for descriptive analysis. Among 21 PPI cases pooled, esomeprazole was the most commonly implicated PPI (52.4%), followed by pantoprazole (19.1%), and omeprazole along with lansoprazole (both 14.3%). The issue of cross-reactivities amongst PPIs remains uncertain. Nonetheless, in situations in which a PPIs are deemed necessary, a prudent approach could be considering a switch to an alternative agent with distinct chemical structure. Conclusion: PPI is commonly used safely as an agent for acid-related gastrointestinal conditions. However, PPI-induced rapid DRESS syndrome can occur, particularly with prior exposure history. ELISpot is an in vitro test, useful in identifying the culprit agent in patients with delayed-type hypersensitivity reaction.

Periodontal disease and risk of atrial fibrillation or atrial flutter: A systematic review and meta-analysis.

Background: We conducted a study to evaluate the risk of atrial fibrillation (AF) and atrial flutter (AFL) in periodontal disease (PD) patients. Methods: Cohort studies that evaluate the risk of AF or AFL in PD patients were included. The risk was expressed in the pooled odd ratio (OR) with 95% confidence interval (CI). Results: A total of four cohort studies were included. We found that patients with PD have a significantly higher risk of AF/AFL compared to those without PD with the pooled OR of 1.33 (95% CI 1.29-1.38; p = 0.357, I 2 = 3.0%). Conclusions: PD increases the risk of AF and AFL.

Pulmonary artery aneurysm in a young female with Takayasu arteritis.

Key Clinical Message: In suspected cases of systemic vasculitis, imaging studies should include the pulmonary artery. This is a rare case of Takayasu arteritis with a large pulmonary aneurysm. Medical management is the first line and vascular intervention if fails prior. Abstract: Takayasu arteritis (TA) should be suspected in young women presented with hypertension, carotidynia, and claudications. Pulmonary artery involvement is frequent, occurring in 20%-50% of patients with TA. However, this case highlights the rare presentation of TA with a large pulmonary aneurysm and minimal aortic involvement. Medical management including immunosuppressive agents and biological therapies remains an important role, with vascular intervention remains as an option if medical therapy failed.

An enigmatic presentation of Escherichia coli endocarditis: Emphasizing the role of brain magnetic resonance imaging.

Key Clinical Message: Infective endocarditis should be considered in any febrile individual with acute onset neurological symptoms. If suspicion is high, a negative brain computed tomography does not virtually exclude embolism, and magnetic resonance imaging is warranted. Abstract: A diagnosis of infective endocarditis (IE) is often delayed, particularly in those infected with unusual organisms. Hereby, we report a case of a female patient presented with dysarthria, confusion, and altered mental status after being treated for Escherichia coli bacteremia. Computed tomography of the brain was unrevealing; however, scattered embolic phenomena were visualized on magnetic resonance imaging (MRI). The case underscores the importance of clinical awareness, particularly in the setting of unusual microorganisms, and the role of brain MRI in the diagnosis of IE.

Accidentally discovered non-communicating membranous ventricular septal aneurysm in a middle-aged male patient.

Membranous interventricular septal (MIVS) aneurysm is a rare often asymptomatic, accidentally discovered congenital anomaly, which might be complicated with right ventricular obstruction, rupture, thromboembolism, and conduction abnormalities.

Ivabradine effects in hospitalized acute heart failure patients: a single center retrospective study.

BACKGROUND: An increased heart rate (HR) is deleterious in patients with decompensated heart failure. Ivabradine, an HR lowering agent which acts by inhibiting the If current in the sinoatrial node, is indicated for chronic heart failure with reduced ejection fraction. However, data regarding the safety and efficacy of ivabradine in acute decompensated heart failure is limited. This retrospective observational study aimed to investigate the effects of ivabradine on morbidity and short-term mortality of hospitalized patients with acute decompensated heart failure. METHODS: A total of 998 patients with acute decompensated heart failure on top of a chronic status from 1/5/2014 to 1/5/2019 who were already on guideline-directed treatment including a beta-blocker were included. Patients were divided into two groups, the first group (No-ivabradine) where patients continued the same dose of beta-blocker alone while the second group (ivabradine group) ivabradine 5 mg BID was added in addition to the same dose of beta-blocker. Patients with hemodynamic instabilities were excluded from the study. Propensity matching was performed to exclude confounding factors. RESULTS: There was no significant difference between groups regarding baseline patient characteristics, laboratory, and echocardiographic data. There were significant differences between groups regarding average HR (87 ± 15 and 90 ± 12 bpm in ivabradine and control groups, consecutively, P = 0.0006*) and length of hospital stay (5.3 ± 2.3 and 7.7 ± 5.6 days in ivabradine and control groups, consecutively, P < 0.0001*). However, there were no differences in rehospitalization and mortality rates at 1 month and 6 months. CONCLUSION: In a retrospective cohort study aimed to investigate the effects of ivabradine on morbidity and short-term mortality of hospitalized patients with acute decompensated heart failure. Ivabradine was associated with significantly lower average HR and length of hospital stay. However, there was no benefit in the reduction of rehospitalization and mortality rates at 1- and 6-month follow-ups.

Ivabradine effects on COVID-19-associated postural orthostatic tachycardia syndrome: a single center prospective study.

BACKGROUND: A wide range of cardiac arrhythmias were reported in the setting of active infection or as a complication of COVID-19. The main pathophysiology can be attributed to dysautonomia or autonomic nervous system dysfunction. Postural orthostatic tachycardia syndrome (POTS) is a complex, multisystemic disorder affecting usually younger age with tachycardia at rest or with minimal effort being the main symptom. Data regarding the safety and efficacy of ivabradine in POTS treatment is limited to small studies and case reports. METHODS: This prospective observational study included a total of 55 COVID-19-associated POTS patients after the exclusion of other causes of tachycardia. Ivabradine 5 mg twice daily was initiated. Re-assessment of patients' symptoms, heart rate, and heart rate variability (HRV) parameters' changes after 3 days of ivabradine therapy was done. RESULTS: The mean age of the included patients was 30.5±6.9 years with 32 patients being males (58.2%). 43 of 55 (78%) of the included patients reported significant improvement of the symptoms within 7 days of ivabradine therapy. 24-hour heart rate (minimum, average, and maximum) was significantly lower (p-value < 0.0001*, = 0.001*, < 0.0001* consecutively) with a significant difference in HRV time-domain parameters (SDNN, rMSSD) (p-value < 0.0001*) after ivabradine therapy. CONCLUSION: In a prospective study that evaluated the effects of ivabradine in post-COVID-19 POTS, patients treated with ivabradine reported improvement of their symptoms within 7 days of ivabradine treatment with a significant reduction of 24-hour average, minimum, and maximum heart rate, and improvement of HRV time domains parameters. Ivabradine might be a useful option to relieve symptoms of tachycardia in COVID-19 POTS. Further research is required to confirm the safety and efficacy of ivabradine in POTS treatment.

High-risk phenotypes of arrhythmic mitral valve prolapse: a systematic review and meta-analysis.

BACKGROUND: Mitral valve prolapse (MVP) is associated with aggravated risk of ventricular tachycardia (VT), ventricular fibrillation (VF) and sudden cardiac death (SCD). There is a lack of specific guideline recommendation regarding risk stratification and management, despite multiple proposed high-risk phenotypes. We performed systematic review and meta-analysis to evaluate high-risk phenotypes for malignant arrhythmias in patients with MVP. METHODS: We comprehensively searched the databases of MEDLINE, SCOPUS, and EMBASE from inception to April 2023. Included studies were cohort and case-control comparing between MVP patients with and without VT, VF, cardiac arrest, ICD placement, or SCD. Data from each study were combined using the random-effects. Pooled odds ratios (OR) and 95% confidence intervals (CI) were calculated. RESULTS: Nine studies from 1985 to 2023 were included involving 2,279 patients with MVP. We found that T-wave inversion (OR 2.52; 95% CI: 1.90-3.33; p < 0.001), bileaflet involvement (OR 2.28; 95% CI: 1.69-3.09; p < 0.001), late gadolinium enhancement (OR 17.05; 95% CI: 3.41-85.22; p < 0.001), mitral annular disjunction (OR 3.71; 95% CI: 1.63-8.41; p < 0.002), and history of syncope (OR 6.96; 95% CI: 1.05-46.01; p = 0.044), but not female (OR 0.96; 95% CI: 0.46-2.01; p = 0.911), redundant leaflets (OR 4.30; 95% CI: 0.81-22.84; p = 0.087), or moderate-to-severe mitral regurgitation (OR 1.24; 95% CI: 0.65-2.37; p = 0.505), were associated with those events. CONCLUSION: Bileaflet prolapse, T-wave inversion, mitral annular disjunction, late gadolinium enhancement, and history of syncope are high-risk phenotypes among population with MVP. Further research is needed to validate the risk stratification model and justify the role of primary prophylaxis against malignant arrhythmias.

Gut Microbiota-Mediated Pharmacokinetic Drug-Drug Interactions between Mycophenolic Acid and Trimethoprim-Sulfamethoxazole in Humans.

Mycophenolic acid (MPA) and trimethoprim-sulfamethoxazole (TMP-SMX) are commonly prescribed together in certain groups of patients, including solid organ transplant recipients. However, little is known about the pharmacokinetic drug-drug interactions (DDIs) between these two medications. Therefore, the present study aimed to determine the effects of TMP-SMX on MPA pharmacokinetics in humans and to find out the relationship between MPA pharmacokinetics and gut microbiota alteration. This study enrolled 16 healthy volunteers to take a single oral dose of 1000 mg mycophenolate mofetil (MMF), a prodrug of MPA, administered without and with concurrent use of TMP-SMX (320/1600 mg/day) for five days. The pharmacokinetic parameters of MPA and its glucuronide (MPAG) were measured using high-performance liquid chromatography. The composition of gut microbiota in stool samples was profiled using a 16S rRNA metagenomic sequencing technique during pre- and post-TMP-SMX treatment. Relative abundance, bacterial co-occurrence networks, and correlations between bacterial abundance and pharmacokinetic parameters were investigated. The results showed a significant decrease in systemic MPA exposure when TMP-SMX was coadministered with MMF. Analysis of the gut microbiome revealed altered relative abundance of two enriched genera, namely the genus Bacteroides and Faecalibacterium, following TMP-SMX treatment. The relative abundance of the genera Bacteroides, [Eubacterium] coprostanoligenes group, [Eubacterium] eligens group, and Ruminococcus appeared to be significantly correlated with systemic MPA exposure. Coadministration of TMP-SMX with MMF resulted in a reduction in systemic MPA exposure. The pharmacokinetic DDIs between these two drugs were attributed to the effect of TMP-SMX, a broad-spectrum antibiotic, on gut microbiota-mediated MPA metabolism.

Association between elevated CHA2DS2-VASC score and contrast-induced nephropathy among patients undergoing percutaneous coronary intervention: a systematic review and meta-analysis.

BACKGROUND: Promising results with the CHA2DS2-VASc risk score (CVRS) have been reported for the prediction of contrast-induced nephropathy (CIN). The aim of this study is to consolidate all the data available and examine the association between elevated CVRS and the incidence of CIN in patients undergoing percutaneous coronary intervention (PCI). METHODS: We systematically searched PubMed, Embase, and Scopus for abstracts and full-text articles from inception to May 2022. Studies were included if they evaluated the association between a high CVRS and the incidence of CIN in patients undergoing PCI. Data were integrated using the random-effects, generic inverse variance method of DerSimonian and Laird. Prospero registration: CRD42022334065. RESULTS: Seven studies from 2016 to 2021 with a total of 7,401 patients were included. In patients undergoing PCI, a high CVRS (≥2: Odds ratio [OR]:2.98, 95% confidence interval [95% CI] 2.25-3.94, p < .01, I2 = 1%, ≥3: OR 4.46, 95% CI 2.27-8.78, p < .01, I2=56% and ≥4: OR:2.75, 95% CI 1.76-4.30, p < .01, I2 = 11%) was significantly associated with an increase incidence for CIN. Subgroup analyses were done in patients with acute coronary syndrome, and association with CIN remained statistically significant (≥2: OR 2.93, 95% CI 2.11-4.07, p < .01, I2=22%and ≥4: OR:2.24, 95% CI 1.36-3.69, p < .01, I2 = 0%,). CONCLUSION: In patients undergoing PCI, an elevated CVRS is associated with an increased risk for CIN. More rigorous studies are needed to clarify this association and to identify strategies to reduce CIN.

CARDIOGENIC SHOCK ASSOCIATED WITH ACUTE NOROVIRUS GASTROENTERITIS: WHAT IS NEEDED TO PROVE CAUSALITY?

Acute myocarditis is a well-recognized condition attributable to a variety of viral illnesses. Common viral aetiologies include enteroviruses including coxsackie, adenovirus, influenza, echovirus, parvovirus B19 and herpesvirus. A high index of suspicion, early diagnosis, and prompt management with supportive anti-failure measures, and in selected cases immunosuppressive therapies including high-dose steroids, might be considered for better outcomes. The authors report a case of sudden onset of acute heart failure complicated by cardiogenic shock caused by viral myocarditis in a patient who initially presented with norovirus gastroenteritis. She had no previous cardiac history or significant cardiovascular risk factors. Prompt medical management for cardiogenic shock for norovirus-induced myocarditis was started, her symptoms gradually improved, and she was discharged safely on regular follow-up. LEARNING POINTS: Viral myocarditis exhibits a wide spectrum of symptoms ranging from non-specific prodromes such as fatigue and myalgia to chest pain, life-threatening arrhythmias, fulminant heart failure, or even sudden cardiac death.Common viral aetiologies for myocarditis include enteroviruses including coxsackie, adenovirus, influenza, echovirus, parvovirus B19 and herpesvirus.A high index of suspicion, early diagnosis, and prompt management with supportive anti-failure measures, and in selected cases immunosuppressive therapies including high-dose steroids, might be considered for better outcomes in cases of acute myocarditis.

A Systematic Review and Meta-Analysis of Posttransplant Anemia With Overall Mortality and Cardiovascular Outcomes Among Kidney Transplant Recipients.

Introduction: Posttransplant anemia is a common finding after kidney transplantation. A previous meta-analysis reported an association between anemia and graft loss. However, data on cardiovascular outcomes have not yet been reported. Objective: We conducted an updated meta-analysis to examine the association between posttransplant anemia and outcomes after transplantation including cardiovascular mortality in adult kidney transplant recipients. Methods: We comprehensively searched the databases of MEDLINE and EMBASE from inception to November 2021. Data from each study were combined using the random-effects model. Generic inverse variance method of DerSimonian and Laird was employed to calculate the risk ratios and 95% CIs. Results: Seventeen studies from August 2006 to April 2019 were included (16 463 kidney transplantation recipients). Posttransplant anemia was associated with overall mortality (pooled risk ratio = 1.72 [1.39, 2.13], I2 = 56%), graft loss (pooled risk ratio = 2.28 [1.77, 2.93], I2 = 94%), cardiovascular death (pooled risk ratio = 2.06 [1.35, 3.16], I2 = 0%), and cardiovascular events (pooled risk ratio = 1.33 [1.10, 1.61], I2 = 0%). Early anemia (≤6 months), compared with late anemia (>6 months), has higher risk of overall mortality and graft loss with a pooled risk ratio of 2.63 (95% CI 1.79-3.86; I2 = 0%) and 2.96 (95% CI 2.29-3.82; I2 = 0%), respectively. Discussion: In addition to increased risk of graft loss, our updated meta-analysis demonstrated that posttransplant anemia was significantly associated with poor outcomes after kidney transplantation including overall mortality, graft loss, cardiovascular death, and cardiovascular events. Future studies are required to assess the effects of treatment strategies for posttransplant anemia on posttransplant outcomes including cardiovascular mortality.

Transient diabetes insipidus after vasopressin discontinuation in cystic fibrosis with septic shock.

Central diabetes insipidus (DI) is an uncommon condition caused by reduced or lack of vasopressin secretion from the posterior pituitary gland, typically caused by gland destruction. Several other causes for central DI have also been proposed. Here we present a case of transient central DI after discontinuation of vasopressin used for septic shock without evidence of overt pituitary damage in a cystic fibrosis patient. The serum sodium concentration peaked at 137 mmol/L in the setting of polyuria within 3 days of vasopressin discontinuation without other identified alternative etiologies. Sodium levels and urine output trended down dramatically with desmopressin administration.

The usefulness of initial serum ferritin level as a predictor of in-hospital mortality in STEMI.

Several studies have shown that elevated serum ferritin level is associated with a higher risk of coronary artery disease. Recently, it has been shown that high serum ferritin levels in men are independently correlated with an increased risk of cardiovascular mortality. This study aimed to investigate the possible correlation between the initial serum ferritin level and in-hospital mortality in patients presenting with ST-elevation myocardial infarction (STEMI). This retrospective cohort study included 890 patients who presented with acute STEMI and underwent successful primary percutaneous coronary intervention (PPCI) according to the standard techniques during the period from 1 May 2020 to 1 May 2021. At the time of admission, an initial serum ferritin level was measured in all patients. Comparison between initial ferritin levels was made between two groups: died and survived. Propensity matching was performed to exclude confounding factors effect. Forty-one patients had in-hospital mortality. There was no significant difference between both groups regarding baseline clinical characteristics. Initial serum ferritin levels were higher in deceased patients, even after propensity matching. In conclusion, even after propensity matching, initial ferritin levels were significantly higher in patients who died after being admitted for STEMI.
