Frequently Asked Questions

How can preventive cardiology help me avoid a future heart attack?

By managing risk factors through lifestyle, medications, and regular check-ups, preventive cardiology aims to reduce the likelihood of plaque buildup and blockages. 

What are the common risk factors for developing coronary artery disease?

High blood pressure, high cholesterol, smoking, diabetes, obesity, physical inactivity, and a family history of heart disease.

How do doctors decide whether a patient needs open-heart surgery or minimally invasive procedures?

The choice depends on the specific condition, anatomical complexity, overall health, and the potential benefits and risks of each approach. 

What lifestyle changes can help prevent coronary artery disease?

Maintain a healthy diet, exercise regularly, avoid smoking, control blood pressure and cholesterol, manage stress, and maintain a healthy weight.

How often should someone with risk factors get screened for heart disease?

Typically, adults over 40 (or earlier if there are risk factors) should have regular check-ups, including blood pressure, cholesterol, and blood sugar assessments, tailored to individual risk profiles.

Can adult congenital heart disease be completely corrected with modern treatments?

Many congenital defects can be effectively corrected or managed with minimally invasive procedures and advanced surgical techniques, allowing patients to lead healthier lives.

When should I consider advanced interventions for blockages that don’t respond to standard treatments?

If medications or basic procedures fail to relieve symptoms or if the blockage is heavily calcified or complex, advanced techniques like rotational atherectomy or specialized stenting may be required.

What are the signs and symptoms of complex coronary artery disease?

Symptoms may include chest pain (angina), shortness of breath, fatigue, dizziness, or episodes of irregular heartbeat. Sometimes, there are no symptoms until a heart attack occurs.
