Heart care
Cardiology cares for the heart and blood vessels. Cardiologists diagnose and treat heart disease, high blood pressure, irregular heartbeat and heart failure, and help prevent heart attacks and strokes.
What it treats
- Chest pain and heart attacks
- High blood pressure and high cholesterol
- Irregular or fast heartbeat (arrhythmia)
- Heart failure and swelling of the feet
- Heart valve disease
- Heart care after angioplasty or bypass surgery
When to see a doctor
- Chest pain or pressure (for sudden or severe pain, call emergency services at once)
- Breathlessness on walking or climbing stairs
- Fainting, palpitations or a family history of heart disease
In an emergency call 108 or 112 in India, or 911 in the United States.
Good to know
- Common tests: ECG, echocardiogram (echo), treadmill test (TMT), lipid profile
- Stopping smoking and walking 30 minutes a day protect the heart
- Take heart medicines every day, even when you feel well
