Frequent premature ventricular contractions (PVCs) may lead to a cardiomyopathy or worsen a pre-existing cardiomyopathy.

Since the initial description of variant angina by Prinzmetal in the late 1950s and the later confirmation of coronary artery spasm as its cause, clinicians have sought a means of reliably testing for this entity.
-
The transradial approach to cardiac catheterization has been steadily gaining ground over the past several years due to advantages over the femoral approach in terms of bleeding risk, vascular injury, procedural cost, and patient comfort.

Atrial fibrillation (AF) is common and catheter ablation has become widely available.

Stenosis of the left main coronary artery has traditionally been an indication for coronary artery bypass graft (CABG) surgery. However, recent studies have shown that percutaneous coronary intervention (PCI) of unprotected left main (ULM) lesions can achieve similar short- and medium-term results to CABG.

Statins have been used in an increasing number and variety of conditions. This large, 10-year cohort study from John Hopkins Neurology Department and Cardiac Surgery Group uses a post-hoc analysis to examine the issue of whether statin use prior to Coronary Bypass Graft Surgery (CABG) would decrease post-op morbidity, specifically stroke and encephalopathy, as well as cognitive decline.

The preoperative use of angiotensin-converting enzyme inhibitors (ACEI) with coronary artery bypass graft (CABG) surgery is controversial. Thus, these investigators from the United Kingdom performed a retrospective, observational study of patients undergoing isolated CABG who did not have cardiogenic shock.
