The heart is a muscular organ that depends on the coronary arteries to supply oxygen-rich blood continuously. But when these arteries narrow or become clogged, the heart muscle cannot receive enough blood flow, which can cause serious harm.
The accumulation of lipids, cholesterol, and other materials in the arterial walls—more commonly referred to as atherosclerosis—is the most frequent cause of heart obstruction. Heart attacks and other severe cardiovascular events may result from this decrease in the heart’s oxygen and nutrition supply.
Bad dieting, smoking, high blood pressure, diabetes, and even a lazy lifestyle are other risk factors that also influence the likelihood of a heart blockage. Early diagnosis and treatment of these blockages prevent further complications and bring about long-term health conditions in the heart.
