TL;DR: The Percutaneous Transluminal Coronary Angioplasty Registry of the National Heart, Lung, and Blood Institute reopened at its previous sites to document changes in angioplastic strategy and outcome in August 1985 and the in-hospital outcome in the new cohort was better.

TL;DR: LV diastolic filling, evaluated noninvasively by radionuclide angiography, is abnormal in a high percentage of patients with CAD at rest independent of LV systolic function or previous myocardial infarction.

TL;DR: The results support the relative safety of PTCA as a method of nonsurgical myocardial revascularization in carefully selected patients and nonfatal complications were significantly influenced by the presence of unstable angina and initial lesion severity > 90% diameter stenosis.

TL;DR: Baseline patient factors independently associated with increased occlusion rates included triple-vessel disease, high risk status for surgery, and acute coronary insufficiency, while Lesion characteristics showing significant positive association included severe stenosis before PTCA, diffuse or multiple discrete morphology, thrombus, and collateral flow from the lesion.

TL;DR: LV diastolic filling is abnormal in a high percentage of patients with HCM, and verapamil normalizes or improves these abnormalities without altering systolic function, and this mechanism may contribute to the clinical improvement of many HCM patients during verAPamil therapy.
