Abstract:
Coronary artery disease (CAD) mortality differs in men and women, leading to the speculation that differences in sex steroids contribute to risk. Controlled clinical trials have shown that estrogen replacement is not cardioprotective in certain women, and recent cross-sectional studies associate low testosterone with a greater incidence of CAD in men. Testosterone has demonstrated effects on insulin resistance, obesity, myocardium, coagulation, inflammation, vasodilation, and endothelial function. Imbalance of sex steroids contributes to adverse cardiac effects in men.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
