Dr. Rituparna Baruah, Senior Consultant Interventional Cardiologist, Apollo Hospitals, Guwahati says, “Heart attacks are frequently caused by coronary artery disease. With this condition, a substance called plaque has built up on the walls of the arteries through a process called atherosclerosis. The coronary arteries narrow as plaque builds. A blood clot can form when plaque within a coronary artery breaks or form ulcers. This blood clot can obstruct blood flow through the coronary arteries, resulting in a heart attack.”
“Heart failure can have various causes. Chronic diseases that weaken or damage the heart are frequently the cause of systolic failure. Coronary artery disease, damage from a previous heart attack, arrhythmias, and heart valve issues are a few examples. Diastolic failure can occur because of disorders that require your heart to work harder to pump blood. When this happens, the heart tissue can harden. High blood pressure, diabetes, and obesity are all causes of diastolic failure. Left-sided heart failure is frequently the cause of right-sided heart failure. As the left side of your heart weakens, blood backs up in the right side, making it work harder,” he adds.
