Does Coronary Heart Disease Affect Lifespan?

Coronary heart disease (CHD) can significantly impact lifespan. In some cases, patients may collapse suddenly and pass away before receiving medical help. These tragic events are often linked to a type known as sudden cardiac death due to CHD. This form of heart disease leads to fatality within an hour of symptom onset, primarily due to severe cardiac arrhythmias such as ventricular tachycardia or ventricular fibrillation. Without prompt medical intervention, these rhythm disturbances can be fatal within minutes.

Other Forms of Coronary Heart Disease and Their Impact

Beyond the sudden death variant, other types of CHD also play a role in reducing life expectancy. For instance, angina caused by coronary artery disease can lead to repeated episodes of chest pain. Over time, frequent angina can weaken the heart muscle, reduce the number of healthy cardiac cells, and even cause myocardial hibernation — a state where heart tissue remains alive but functions poorly. This condition can ultimately progress to heart failure.

Heart Failure and Long-Term Risks

Chronic heart damage from recurring angina or untreated episodes can significantly impair the heart's ability to pump blood efficiently. As heart function declines, patients may experience fatigue, shortness of breath, and fluid retention, all of which signal worsening heart failure and a higher risk of mortality.

Acute Myocardial Infarction: A Major Threat

Another critical form of CHD is acute myocardial infarction, commonly known as a heart attack. This condition is a leading cause of both sudden death and long-term mortality. When a coronary artery becomes completely blocked, the heart muscle is deprived of oxygen, leading to tissue death. Without immediate treatment, the consequences can be fatal or leave the individual with lasting heart damage that increases the risk of future cardiac events.

In conclusion, coronary heart disease unquestionably affects lifespan. Whether through sudden cardiac arrest, progressive heart failure, or acute heart attacks, CHD remains a major contributor to mortality worldwide. Early diagnosis, lifestyle changes, and appropriate medical care are essential for improving prognosis and extending life expectancy.
