Coronary Artery Disease (CAD)
Introduction
Homeostasis in coronary arteries is maintained by zinc (Zn) and nitric oxide (NO) since
they are tightly coordinated (Rehman and Rehman, 2019). Zn ions are responsible for
dimerization of endothelial nitric oxide synthase. Thus, NO is generated causing rapid
mobilization of endothelial Zn stores to produce labile Zn, necessary for the action of NO in
vasodilation and vascular cytoprotection (Zalewski, et al. 2018).
Summary
CAD begins with atherosclerosis, an inflammatory state of medium-sized arteries
accelerated by factors like increased blood pressure, genetics, diabetes, and high cholesterol
(Klabunde, 2017). Coronary atherosclerosis causes the inner walls of the coronary arteries to
thicken hence narrowing their lumen (Ambrose and Singh 2015). Atherosclerosis is
characterized by a build-up of fats, fibrous materials and inflammatory particles in the arterial
walls (Sayols-Baixeras, et al. 2014). CAD has got various medications in its name with
Acetylsalicylic acid (ASA) as one of the main ones. ASA is found in painkillers like Aspirin
(Institute for Quality and Efficiency in Health Care, 2017), a nonsteroidal anti-inflammatory
drug (NSAID).
Conclusion
ASA in aspirin inhibits production of prostaglandin hence its analgesic effects.
Prostaglandin cause contraction in muscles, dilation, and constriction of blood vessels, lead to
elevated blood pressure and contributes to inflammation (Fritzel, 2019). ASA in aspirin gets
absorbed in the gastrointestinal tract after ingestion and then distributed to all body tissues. All

doses of the drug can be administered orally and intravenously (Chýlová, et al. 2015). Aspirin is
associated with side effects like gastrointestinal ulcerations, heartburn, bleeding, headache and
gastritis (Cunha 2019). Various health benefits are attributed to frequent physical exercise thus,
is a recommended prevention of primary and secondary CV. However, athletes experience
clinical events like acute myocardial infarction and sudden cardiac death (Dores, et al. 2018).
Thus, since CAD is a neurohormonal imbalance, it can be managed.
