What often results from inadequate oxygen to the myocardium?

• A. Reversible injury
• B. Ischemia
• C. Cardiac arrest
• D. Heart failure

Answer: (B)

The correct answer is ischemia, which refers to a condition where there is insufficient blood flow to the heart muscle, leading to a lack of oxygen (O2) supply to the myocardium. This inadequate oxygen delivery can occur due to factors such as narrowed coronary arteries, blood clots, or other obstructions in blood flow. Ischemia can manifest as chest pain or angina and, if prolonged, can lead to more severe outcomes, including myocardial infarction (heart attack). When the heart muscle does not receive enough oxygen, it cannot function optimally, affecting its ability to pump blood effectively. If the ischemic condition is resolved quickly, it can lead to reversible injury and restore function to the affected myocardium. However, persistent ischemia can progress to more severe conditions, but the initial response to inadequate oxygen is primarily ischemia.
