Risk of death and myocardial infarction in patients with peripheral arterial disease undergoing percutaneous coronary intervention (from the National Heart, Lung and Blood Institute Dynamic Registry).

Patients with peripheral arterial disease (PAD) undergoing percutaneous coronary intervention (PCI) are at high risk for adverse cardiovascular events. Trends over time in outcomes with advances in PCI and medical therapy are unknown. We evaluated 866 patients with PAD in the National Heart, Lung, and Blood Institute (NHLBI) Dynamic Registry undergoing PCI according to treatment eras: the early bare metal stent (BMS) era (wave 1, 1997 to 1998, n = 180), the BMS era (waves 2 and 3, 1999 and 2001 to 2002, n = 339), and the drug-eluting stent (DES) era (waves 4 and 5, 2004 and 2006, n = 347).

Coronary slow flow phenomenon and risk for sudden cardiac death due to ventricular arrhythmias: a case report and review of literature.

We report a case of coronary slow flow phenomenon (CSFP) in a patient who underwent coronary angiography due to anginal chest pain and recurrent syncope with complete normalization of flow after intracoronary adenosine. He was noted to have multiple episodes of nonsustained ventricular tachycardia on holter monitor and increased QTc dispersion on surface electrocardiogram (EKG). He responded very well to oral dipyridamole therapy with complete resolution of his symptoms and no episodes of ventricular tachycardia on the event recorder at 3 months.
