Which condition is a group of cardiac disabilities due to insufficient oxygenated blood to the heart?

• A. Ischemic heart disease
• B. Myocardial infarction
• C. Angina pectoris
• D. Arrhythmia

Answer: (A)

Ischemic heart disease describes a group of heart problems caused by reduced blood flow and oxygen to the heart muscle, usually because the coronary arteries are narrowed or blocked. When the heart doesn’t receive enough oxygen, it can’t work as well, especially during activity, leading to various manifestations that stem from that same underlying issue. Angina pectoris appears as chest pain due to transient ischemia, while it serves as a symptom within this broader category. Myocardial infarction, on the other hand, is a specific event where prolonged lack of blood flow causes heart tissue damage or death. Arrhythmias are abnormalities in rhythm or electrical activity of the heart and aren’t defined by a shortage of oxygen to the heart muscle, although ischemia can contribute to rhythm problems. Because ischemic heart disease covers the broader set of disorders arising from insufficient oxygenated blood reaching the heart, it best fits the description.
