Cardiovascular Diseases

Cardiovascular diseases are disorders of the heart and blood vessels. These diseases can lead to serious health problems. Understanding them can help in prevention and treatment.

Heart Attack

A heart attack occurs when blood flow to the heart is blocked. This blockage can damage or destroy part of the heart muscle. Symptoms include chest pain, shortness of breath, and nausea. Immediate medical attention is crucial.

Stroke

A stroke happens when blood supply to the brain is interrupted. This interruption can cause brain cells to die within minutes. Symptoms include sudden weakness, confusion, and difficulty speaking. Quick treatment can save lives and reduce disability.

Hypertension

Hypertension, or high blood pressure, forces the heart to work harder. This condition can lead to heart attack, stroke, and other problems. It’s often called the “silent killer” because it shows no symptoms. Regular check-ups can help detect and manage it.

Cardiovascular Disease	Key Symptoms	Action
Heart Attack	Chest pain, shortness of breath, nausea	Seek immediate medical attention
