Cardiology

A Cardiologist is a doctor who specializes in preventing, diagnosing and treating various medical diseases and conditions related to heart and blood vessels, such as vascular diseases, heart attacks, congenital heart defects, heart rhythm disturbance, heart failures, coronary artery disease, etc. They are responsible for counselling and consulting the patients regarding maintaining cardiac fitness and management of cholesterol. 

1. Medications: Many heart conditions can be managed with medications. These drugs may include:

   • Beta-blockers: To reduce heart rate and blood pressure.

   • Angiotensin-converting enzyme (ACE) inhibitors: To relax blood vessels and lower blood pressure.

   • Antiplatelet agents: To prevent blood clots.

   • Statins: To lower cholesterol levels.

   • Diuretics: To reduce fluid buildup in the body.

2. Lifestyle Modifications: Making healthy lifestyle changes can significantly improve heart health. These changes may include:

   • Dietary Changes: Adopting a heart-healthy diet low in saturated fats, cholesterol, and sodium.

   • Regular Exercise: Engaging in regular physical activity to strengthen the heart and improve overall cardiovascular health.

   • Smoking Cessation: Quitting smoking to reduce the risk of heart disease.

   • Stress Management: Learning stress-reduction techniques, such as meditation and relaxation exercises.

3. Interventional Procedures: In some cases, minimally invasive procedures may be necessary. These include:

   • Angioplasty: A procedure to open blocked or narrowed arteries using a balloon-like device.

   • Stent Placement: After angioplasty, a stent (a small mesh tube) may be inserted to help keep the artery open.

   • Ablation: Used to treat arrhythmias by destroying abnormal heart tissue.

4. Surgical Procedures: For more severe heart conditions, surgery may be required. Common cardiac surgeries include:

   • Coronary Artery Bypass Grafting (CABG): Used to treat severe coronary artery disease by creating new routes for blood flow around blocked arteries.

   • Heart Valve Replacement or Repair: Necessary when heart valves become damaged or diseased.

   • Heart Transplant: Reserved for individuals with end-stage heart failure when other treatments are no longer effective.

5. Implantable Devices: Certain heart conditions may require implantation of devices like:

   • Pacemakers: Used to regulate abnormal heart rhythms by sending electrical impulses to the heart.

   • Implantable Cardioverter Defibrillators (ICDs): Monitors heart rhythms and delivers shocks to correct life-threatening arrhythmias.

6. Cardiac Rehabilitation: After treatment, cardiac rehabilitation programs can help individuals recover, regain strength, and learn how to manage their condition through exercise and education.

Common types of invasive cardiology:

• Angioplasty: When plaque clogs your arteries, it becomes difficult for blood to flow normally. Angioplasty inserts a tiny balloon into your clogged vein and pushes plaque against the walls, allowing for increased blood flow.
• Stenting: Stenting is usually done in conjunction with angioplasty. A cardiac stent is a small metal coil which permanently holds a clogged vein open.
