Effectiveness of Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting in Patients With End-Stage Renal Disease.

The optimal coronary revascularization strategy (coronary artery bypass grafting [CABG] or percutaneous coronary intervention [PCI]) in patients with end-stage renal disease (ESRD) remains uncertain. We performed an updated systematic review and meta-analysis of observational studies comparing CABG and PCI in patients with ESRD using a random-effects model for the primary outcome of long-term all-cause mortality. Our review registered through PROSPERO included observational studies published after 2011 to ensure overlap with previous studies and identified 7 new studies for a total of 23.

Spontaneous Coronary Artery Dissection with Cardiac Tamponade.

Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome. Clinical presentation ranges from chest pain alone to ST-segment-elevation myocardial infarction, ventricular fibrillation, and sudden death. The treatment of patients with spontaneous coronary artery dissection is challenging because the disease pathophysiology is unclear, optimal treatment is unknown, and short- and long-term prognostic data are minimal.

Comparing Anxiety and Depression in Patients With Takotsubo Stress Cardiomyopathy to Those With Acute Coronary Syndrome.

Purpose: To determine whether anxiety or depression is associated with takotsubo stress cardiomyopathy (TSCM).

Methods: A retrospective case-control study was conducted among 73 TSCM cases and 111 acute coronary syndrome (ACS) controls matched for age, sex, and cardiac catheterization date. The study was conducted between May 1, 2009, and February 28, 2010.
