RESUMEN
OBJECTIVE: Coronary artery calcification (CAC) is one of the paramount hurdles for percutaneous coronary intervention (PCI) since it impedes stent delivery and complete expansion. This study intended to evaluate the short-term clinical and procedural outcomes comparing rotational atherectomy (RA) and orbital atherectomy (OA) in patients with heavily calcified coronary lesions undergoing PCI. Design: This systematic review and meta-analysis included all head-to-head published comparisons of coronary RA versus OA. Procedural endpoints and post-procedural clinical outcomes (30 days/in-hospital), were compared. RevMan 5.3 software was used for data analysis. Results: Seven retrospective observational investigations with a total of 4623 patients, including 3203 patients in the RA group and 1420 patients in the OA group, were incorporated. Compared with OA, the RA group was associated with a higher incidence of myocardial infarction at short-term follow-up (OR: 1.56, 95% CI: 1.07-2.29, p = .02, I2 = 0%). No difference was noted among other short-term post-procedural clinical outcomes including all-cause mortality, target vessel revascularization, or major adverse cardiac events. Among procedural complications, RA was associated with reduced coronary artery dissection and arterial perforation. Increased fluoroscopy time was observed in the RA cohort as compared with OA (MD: 4.78, 95% CI: 2.25-7.30, p = .0002, I2 = 80%). Conclusion: RA was associated with fewer vascular complications, but at a cost of higher incidence of myocardial infarction and higher fluoroscopy time compared with OA, at short term follow-up. OA is a safe and effective alternative for the management of CAC.

BACKGROUND: With rising trends of prediabetes in the geriatric population, we aim to assess the impact of alcohol use disorder (AUD) on the outcomes of patients with prediabetes. METHODS: Hospitalisations amongst the patients (≥65 years) with prediabetes were identified with a diagnosis of AUD and in-hospital stroke using the National Inpatient Sample database (2007-2014). We compared demographics, comorbidities, all-cause mortality, stroke rate and resource utilisation in the elderly prediabetes patients with vs without AUD. Primary outcomes of interest were all-cause mortality and stroke rate, whereas secondary outcomes were the length of stay (days), disposition and resource utilisation in the AUD cohort as compared to the non-AUD cohort. RESULTS: We had a total of 1.7 million hospitalisations amongst elderly patients with prediabetes, 2.8% (n = 47 962) had AUD. The AUD cohort was more often younger (71 vs 77 years), male (74.1% vs 43.5%) and nonelectively (84.5% vs 78.3%) admitted than non-AUD cohort. The AUD cohort more often consisted of African Americans (9.0% vs 6.6%) and Hispanics (5.3% vs 5.1%) than non-AUD cohort. The AUD cohort showed higher rates of smoking, drug abuse, chronic obstructive pulmonary disease, coagulopathy, peripheral vascular disease and fluid-electrolyte disorders whereas a lower rate of cardiovascular risk factors than non-AUD cohort. All-cause mortality (4.4% vs 3.9%) and stroke (5.5% vs 4.8%, aOR 1.33, 95% CI 1.28-1.39) were significantly higher in the AUD cohort with prolonged stay, higher charges and frequent transfers than non-AUD cohort. CONCLUSION: AUD in the elderly prediabetes patients increases the stroke risk by up to 33% which can adversely influence the survival rate and healthcare infrastructure.

Typical takotsubo cardiomyopathy (TCM) is a reversible form of myocardial injury that presents with a characteristic ballooning abnormality of the left ventricular apex. Typical TCM has been associated with myocardial bridging; however, mid-ventricular variant TCM has not. We describe a rare case of mid-ventricular variant TCM with a coexisting left anterior descending artery myocardial bridge and discuss management strategies. Furthermore, we propose potential pathophysiological mechanisms that may contribute to the symptomatic presentation of both conditions as a manifestation of common etiological factors.
RESUMEN
INTRODUCTION: Long-term follow-up results of various trials comparing Zotarolimus eluting stents (ZES) with Everolimus eluting stents (EES) have been published recently. Additionally, over the last decade, there have been new trials comparing the ZES with various commercially available EES. We aim to conduct an updated meta-analysis in light of new evidence from randomized controlled trials (RCTs) to provide comprehensive evidence regarding the temporal trends in the clinical outcomes. METHODS: A comprehensive literature search was conducted across PubMed, Cochrane, and Embase. RCTs comparing ZES with EES for short (<2 years), intermediate (2-3 years), and long-term follow-ups (3-5 years) were included. Relative risk was used to pool the dichotomous outcomes using the random effects model employing the inverse variance method. All statistical analysis was conducted using Revman 5.4. RESULTS: A total of 18 studies reporting data at different follow-ups for nine trials (n = 14319) were included. At short-term follow-up (<2 years), there were no significant differences between the two types of stents (all-cause death, cardiac death, Major adverse cardiovascular events (MACE), target vessel myocardial infarction, definite or probable stent thrombosis or safety outcomes (target vessel revascularization, target lesion revascularization, target vessel failure, target lesion failure). At intermediate follow-up (2-3 years), EES was superior to ZES for reducing target lesion revascularization (RR = 1.28, 95% CI = 1.05-1.58, p < 0.05). At long-term follow-up (3-5 years), there were no significant differences between the two groups for any of the pooled outcomes (p > 0.05). CONCLUSION: ZES and EES have similar safety and efficacy at short, intermediate, and long-term follow-ups.

Background. Coronavirus 2019 (COVID-19) was initially identified approximately in December 2019 at Wuhan, China, as patients presented with vague prodromal and respiratory symptoms. With the developing investigation of its clinical manifestation, cardiac symptoms have been widely reported including acute coronary syndromes, myocarditis, arrhythmias, heart failure, and cardiac arrest. Case Summary. An 84 year-old male with history of coronary artery disease, hypertension, and hyperlipidemia presented to an outside urgent care with prodromal symptoms. The patient had received the second Pfizer vaccine three months prior. This presentation, he was found to be COVID-19 positive as well as bradycardic with a complete AV block. He was transferred to a tertiary center for further evaluation and management. However, after transfer, the patient refused further invasive cardiac interventions and after medical therapy was discharged home in complete AV block. Discussion. We report a novel case of a Pfizer-vaccinated patient whose initial presenting symptoms of COVID-19 included a complete AV block as well as the challenges and difficulties in approaching such patients. Although this patient's etiology of his complete AV block may result from multiple factors, given the acuity in setting of concurrent COVID-19 infections, top differentials include viral myocarditis, COVID-19-induced Takotsubo cardiomyopathy complicated by a complete AV-block, or a direct conduction pathway infection. Management of patients should focus on a multidisciplinary approach, and prevention is critical via vaccination.
RESUMEN
BACKGROUND: Studies have suggested that atrial fibrillation (AF) in patients with rheumatic diseases (RD) may be due to inflammation. AIM: To determine the highest association of AF among hospitalized RD patients and to determine morbidity and mortality associated with AF in hospitalized patients with RD. METHODS: The National inpatient sample database from October 2015 to December 2017 was analyzed to identify hospitalized patients with RD with and without AF. A subgroup analysis was performed comparing outcomes of AF among different RD. RESULTS: The prevalence of AF was 23.9% among all patients with RD (n = 3949203). Among the RD subgroup, the prevalence of AF was highest in polymyalgia rheumatica (33.2%), gout (30.2%), and pseudogout (27.1%). After adjusting for comorbidities, the odds of having AF were increased with gout (1.25), vasculitis (1.19), polymyalgia rheumatica (1.15), dermatopolymyositis (1.14), psoriatic arthropathy (1.12), lupus (1.09), rheumatoid arthritis (1.05) and pseudogout (1.04). In contrast, enteropathic arthropathy (0.44), scleroderma (0.96), ankylosing spondylitis (0.96), and Sjorgen's syndrome (0.94) had a decreased association of AF. The mortality, length of stay, and hospitalization costs were higher in patients with RD having AF vs without AF. Among the RD subgroup, the highest mortality was found with scleroderma (4.8%), followed by vasculitis (4%) and dermatopolymyositis (3.5%). CONCLUSION: A highest association of AF was found with gout followed by vasculitis, and polymyalgia rheumatica when compared to other RD. Mortality was two-fold higher in patients with RD with AF.
RESUMEN
Background Systemic Sclerosis (SSc) is associated with chronic inflammation which leads to macrophage activation and thus vascular insult and fibrosis. Macrophage activation is shown to precede Takotsubo syndrome (TTS) which may be a common pathophysiologic link to SSc. Methods We queried the National Inpatient Sample (2008-2014) for adult SSc-related hospitalizations and TTS using relevant International Classification of Diseases Clinical Modification, 9th Revision codes. We assessed the prevalence and trends in TTS during this time. We further assessed demographics, comorbidities, and outcomes were in SSc with and without TTS. The primary outcomes of the analysis were all-cause mortality and in-hospital complications including cardiac arrest and acute myocardial infarction (AMI), arrhythmias, and venous thromboembolism, and stroke. Results A total of 213,728 SSc-related hospitalizations were found, of which 357 experienced TTS (0.2%) with rising trends in TTS from 2008-2014 (0.06% to 0.3%, relative increase of 24%, ptrend<0.001). The TTS cohort was older (median age 68 vs 62 years), with 92.8% females and 80.1% white adults with TTS (p<0.001). Co-morbidities were higher in the TTS cohort including hypertension (62.2% vs. 51.5%, p<0.001), dyslipidemia (41.5% vs. 22.8, p<0.001), smoking (28.9% vs. 20.1%, p<0.001), peripheral vascular disease (17.8% vs. 9.1%, p<0.001), uncomplicated diabetes (18.1% vs. 11.9%, p<0.001). The all-cause in-hospital mortality (11% vs. 4.6%; adjusted odds ratio=1.82, 95% confidence interval: 1.21-2.72, p<0.005), cardiovascular complications like AMI (29% vs. 2.9%,p<0.001), arrhythmias (38.9% vs. 21.5%, p<0.001), and median length of stay [6 vs. 4 days] were significantly higher in the TTS cohort as compared to the non-TTS cohort. Conclusion This analysis revealed a nearly 10 times higher prevalence of TTS in SSc-related hospitalizations compared to the general inpatient population. Concomitant TTS occurrence in SSc-related hospitalizations led to nearly two times higher odds of all-cause mortality. Cardiovascular co-morbidities in SSc may increase the risk of TTS and worsened outcomes.
RESUMEN
BACKGROUND: Studies comparing characteristics and in-hospital outcomes for heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF) for hospitalisations undergoing percutaneous coronary intervention (PCI) for ST-segment elevated myocardial infarction (STEMI) remain limited. AIM: This sought to investigate characteristics and in-hospital outcomes for HFpEF and HFpEF hospitalisations undergoing STEMI-PCI. METHODS: The National inpatient sample database from years 2012 to 2014 was queried and appropriate International Classification of Disease, Ninth Revision, Clinical Modification codes were utilised to identify study cohorts. A total of 400,590 hospitalisations underwent STEMI-PCI, of which, 31,180 presented with acute heart failure (89.3% with acute HFrEF and 10.7% with acute HFpEF). The HFpEF cohort was older (65.6 vs. 69.9 years), consisted of more females (35% vs. 48.7%), and presented with significantly higher comorbidities as demonstrated by higher Charlson's Comorbidity Index ≥ 3 (59.6 vs. 68%) (P < 0.001 for all). However, lower in-hospital mortality (9.2% vs. 8.0%, P = 0.04) was observed with HFpEF hospitalisations, which accompanied by lower mechanical circulatory support (MCS) device (20.3 vs. 12.3%, P < 0.001) use after propensity score matching. These translated to lower median hospitalisation cost ($28,116 vs. $27,823, P < 0.001) with HFpEF without significant change in median length of hospitalisation stay (6 vs. 6 days, P = 0.08). CONCLUSIONS: This study highlights the distinct risk profile for hospitalisations with HFpEF undergoing STEMI-PCI. HFpEF hospitalisations are associated with the lesser need for MCS, lower in-hospital mortality, and ultimately lower hospitalisation cost compared to HFrEF.

INTRODUCTION: In frontotemporal dementia (FTD) and Alzheimer's disease (AD), central autonomic structures get affected early. An insight into autonomic functions in these patients is likely to be of diagnostic importance and thus help in prognosticating and also probably explain unexplained sudden death in some of these patients. OBJECTIVES: The objective of this study is to identify autonomic dysfunction prevailing in patients. Then, if there is dysfunction, is the pattern same or different in these two conditions. And if different it will serve as an additional biomarker for specific diagnosis. PATIENTS AND METHODS: There were 25 patients and 25 controls and six patients and three controls in AD and FTD groups, respectively. The participants who were recruited were assessed for heart rate variability and conventional cardiac autonomic function testing. The parameters were analyzed using LabChart version 7 software and compared with control population using appropriate statistical methods using SPSS version 22 software. RESULTS: The mean overall total power was low in the FTD group (P < 0.001), and there was significant reduction in the standard deviation of normal-to-normal intervals and root mean square of successive differences (P < 0.001) with elevated sympathovagal balance in the FTD group (P = 0.04). Patients with AD also showed sympathetic dominance, but there was in addition parasympathetic suppression unlike in the FTD group. CONCLUSION: This study reveals autonomic dysfunction in patients with FTD and AD. Both conditions show sympathetic dominance, probably consecutive to the involvement of central autonomic regulatory structures as a shared domain. It remains to be confirmed if these findings are the cause or effect of neurodegeneration and might open up newer territories of research based on the causal role of neurotransmitters in these regions and thus lead to novel therapeutic options such as yoga. The presence of parasympathetic suppression in AD in addition helps differentiate these two conditions.
