A weak heart is typically caused by a condition called heart failure, which occurs when the heart is unable to pump enough blood to meet the body’s needs. Some common causes of heart failure and a weak heart include:
- Coronary artery disease: This occurs when the blood vessels that supply the heart muscle with oxygen and nutrients become narrowed or blocked, leading to a decrease in blood flow to the heart and a weakened heart muscle.
- High blood pressure: Chronic high blood pressure can cause the heart to work harder than it should, leading to a weakened heart muscle.
- Diabetes: Diabetes can damage the blood vessels and nerves that control the heart, which can lead to heart failure.
- Cardiomyopathy: This is a disease that affects the heart muscle, causing it to become weak and unable to pump blood effectively.
- Valvular heart disease: This occurs when one or more of the heart valves do not function properly, leading to a weakened heart.
- Infections or inflammation of the heart: This can damage the heart muscle and lead to heart failure.
- Congenital heart defects: These are defects in the heart that are present at birth and can cause a weakened heart over time.
- Lifestyle factors: Unhealthy lifestyle habits such as smoking, excessive alcohol consumption, and a sedentary lifestyle can also contribute to a weak heart over time.
