Objectives: Using 2 sequential studies in HOPE (Heart Outcomes Prevention Evaluation) study-type patients, the aims of this study were: 1) to test the hypothesis that ramipril improves platelet nitric oxide (NO) responsiveness: and 2) to explore biochemical and physiological effects of ramipril in a cohort selected on the basis of platelet NO resistance.
Background: Ramipril prevents cardiovascular events, but the bases for these effects remain uncertain. NO resistance at both the platelet and vascular levels is present in a substantial proportion of patients with diabetes or ischemic heart disease and is an independent risk factor for cardiovascular events.
Purpose: The A-HeFT trial demonstrated incremental survival with hydralazine/isosorbide dinitrate combination in African-American patients with chronic heart failure (CHF). It has been suggested that hydralazine might enhance nitric oxide (NO)-mediated effects of organic nitrates by decreasing superoxide (O (2) (-) ) formation, one of the factors inducing NO resistance. We evaluated whether hydralazine therapy potentiates nitrate-induced vasodilation and inhibition of platelet aggregation by ameliorating NO resistance.

Background: The CSFP is characterized by delayed vessel opacification on angiography (Thrombolysis In Myocardial Infarction [TIMI]-2 flow) in the absence of obstructive epicardial coronary disease and is often associated with recurrent chest pain.
Methods: A total of 10 CSFP patients (46 +/- 9 years) underwent angiography before and 30 min after 50 mg mibefradil; off-line blinded analysis of angiographic data included comparisons of epicardial vessel diameter, TIMI flow grade and TIMI frame count.
