Impact of COVID-19 infection on baseline autonomic symptoms in patients with preexisting postural tachycardia syndrome and orthostatic intolerance: A retrospective study.

Background: Postural orthostatic tachycardia syndrome (POTS) and dysautonomia following a SARS-CoV-2 infection have been recently reported. The underlying mechanism of dysautonomia is not well understood. The impact of this viral illness on the underlying autonomic symptoms has not been studied in patients with a pre-existing POTS diagnosis.

Prevalence of Heart Failure With Preserved Ejection Fraction in Patients Undergoing Atrial Fibrillation Ablation Based on Resting and Post-Tachycardia Pacing Left Atrial Pressure.

Atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) are frequent co-morbid conditions. In patients with symptomatic AF and preserved left ventricular ejection fraction the clinical diagnosis of HFpEF may be difficult, as history, examination, and echocardiography are not sensitive or specific. This study sought to assess the prevalence of HFpEF in patients undergoing AF ablation utilizing resting and post-tachycardia pacing left atrial pressure (LAP) measurements.

Low voltage area guided substrate modification in nonparoxysmal atrial fibrillation: A systematic review and meta-analysis.

Background: Low voltage areas (LVAs) on left atrial (LA) bipolar voltage mapping correlate with areas of fibrosis. LVAs guided substrate modification was hypothesized to improve the success rate of atrial fibrillation (AF) ablation particularly in nonparoxysmal AF population. However, randomized controlled trials (RCTs) and observational studies yielded mixed results.

Outcomes of Coronary Artery Bypass Grafting in Patients With Previous Mediastinal Radiation.

Studies have shown that patients with radiation therapy-associated coronary artery disease tend to have worse outcomes with percutaneous revascularization. Previous irradiation has been linked with future internal mammary artery graft disease. Studies investigating the outcomes of coronary artery bypass surgery (CABG) among patients with previous radiation are limited.

Short-term Outcomes of Hypertensive Crises in Patients with Orthostatic Hypotension.

Supine hypertension-orthostatic hypotension disease poses a management challenge to clinicians. Data on short term outcomes of patients with orthostatic hypotension (OH) who are hospitalized with hypertensive (HTN) crises is lacking. The Nationwide Readmission Database 2016-2019 was queried for all hospitalizations of HTN crises.

Role of Adjunctive Cryoballoon Left Atrial Posterior Wall Isolation in Non-paroxysmal Atrial Fibrillation: A Meta-analysis.

Progressive remodeling of left atrial posterior wall (LAPW) plays an important role in the pathology of persistent/ long-standing persistent atrial fibrillation. The role of pulmonary veins isolation (PVI) and adjunctive LAPW isolation using cryothermal energy in non-paroxysmal atrial fibrillation is yet to be established. The databases of Pubmed, EMBASE and Cochrane Central databases were searched from inception to April 2022.

Dirty Jobs: Macrophages at the Heart of Cardiovascular Disease.

Cardiovascular disease (CVD) is one of the greatest public health concerns and is the leading cause of morbidity and mortality in the United States and worldwide. CVD is a broad yet complex term referring to numerous heart and vascular conditions, all with varying pathologies. Macrophages are one of the key factors in the development of these conditions.

Outcomes and Resource Utilization of Atrial Fibrillation Hospitalizations With Type 2 Myocardial Infarction.

Scarce data exist on the prognostic impact of type 2 myocardial infarction (MI) in patients with AF. The Nationwide Readmission Database 2018 was queried for primary AF hospitalizations with and without type 2 MI. Complex samples multivariable logistic and linear regression models were used to determine the association between type 2 MI and outcomes (in-hospital mortality, index length of stay [LOS], hospital costs, discharge to nursing facility, and 30-day all-cause readmissions).

Coronary artery aneurysms: outcomes following medical, percutaneous interventional and surgical management.

Background: Coronary artery aneurysms (CAAs) are increasingly diagnosed on coronary angiography; however, controversies persist regarding their optimal management. In the present study, we analysed the long-term outcomes of patients with CAAs following three different management strategies.

Methods: We performed a retrospective review of patient records with documented CAA diagnosis between 2000 and 2005.

Effect of High-Density Lipoprotein Cholesterol Levels on Overall Survival and Major Adverse Cardiovascular and Cerebrovascular Events.

Several studies designed to augment high density lipoprotein (HDL) levels have so far been unsuccessful in reducing rates of major adverse cardiovascular and cerebrovascular events (MACCE). In this study, we report the effect of HDL-C levels on overall survival outcomes and rates of MACCE following percutaneous coronary intervention (PCI). We reviewed patients who underwent PCI at the Cleveland Clinic from 2005 to 2017 and followed them through the end of 2018.

Adverse clinical outcomes in patients undergoing both PCI and TAVR: Analysis from a pooled multi-center registry.

Background: There is a paucity of data regarding the optimum timing of PCI in relation to TAVR.

Objective: We compared the major adverse cardiovascular and cerebrovascular events (MACCE) rates among patients who underwent percutaneous coronary intervention (PCI) before transcatheter aortic valve replacement (TAVR) with those who received PCI with/after TAVR.

Methods: In this multicenter study, we pooled all consecutive patients who underwent TAVR at three high volume centers.

Drug-Eluting Stents Versus Bare-Metal Stents in Large Coronary Artery Revascularization: Systematic Review and Meta-Analysis.

Objectives: We aim to determine if drug eluting stents (DES) are better than bare-metal stents (BMS) in large coronary artery (diameter ≥ 3 mm) percutaneous coronary intervention (PCI).

Background: DES have become the standard of care for PCI in coronary artery disease (CAD). However, the superiority of DES over BMS in large vessel CAD is not clear and previous studies have shown conflicting results.

Safety and Long-Term Patency of Endovascular Therapy for Infrarenal Aortic Disease: Single-Center Experience and Review of the Literature.

Objectives: Endovascular therapy (EVT) has emerged as an alternative to surgery for the treatment of symptomatic infrarenal aortic stenosis (IAS). However, long-term outcomes with EVT are unknown.

Methods: We performed a retrospective review of patients with IAS treated with the endovascular approach at the University of Toledo Medical Center, Toledo, Ohio.

Outcomes of patients with severe tricuspid regurgitation and congestive heart failure.

Objectives: A substantial number of patients with severe tricuspid regurgitation (TR) and congestive heart failure (CHF) are medically managed without undergoing corrective surgery. We sought to assess the characteristics and outcomes of CHF patients who underwent tricuspid valve surgery (TVS), compared with those who did not.

Methods: Retrospective observational study involving 2556 consecutive patients with severe TR from the Cleveland Clinic Echocardiographic Database.
