About the Health Information

Across the world, cardiovascular disease continues to be a major cause of death, and it often develops without obvious early warning signs. Symptoms usually surface only after the disease has advanced, making early detection essential.

Cardiac screening plays a vital role in detecting problems early, reducing risks, and guiding lifestyle or medical management to protect your heart health.

Cardiac screening involves a series of tests designed to evaluate heart function and identify risks for conditions like:

• Coronary artery disease
• Arrhythmias (irregular heart rhythms)
• Structural abnormalities
• Stroke and heart attack risk factors

Because heart disease often develops unnoticed, screening is essential for individuals with risk factors.

Although many heart conditions cause no symptoms initially, certain signs should raise concern, such as:

• Chest pain or pressure
• Shortness of breath
• Palpitations or irregular heartbeat
• Dizziness or fainting
• Fatigue with minimal effort

Doctors usually advise cardiac screening for people with risk factors like:

• Family history of heart disease
• High blood pressure or cholesterol
• Diabetes or obesity
• Smoking habits
• Sedentary lifestyle
• Men above 40 years or women above 50 years

A combination of inherited traits, daily habits, and underlying health conditions contributes to the development of heart disease:

• Age: Older adults face higher risks.
• Genetics: Family history increases vulnerability.
• Lifestyle: Unhealthy diet, smoking, alcohol, and inactivity.
• Medical conditions: Diabetes, hypertension, and high cholesterol.
• Other factors: Obesity, stress, poor sleep, and inflammatory diseases.

Depending on your profile, a cardiologist might suggest tests such as:

• Physical exam – Pulse, blood pressure, heart sounds
• Electrocardiogram (ECG/EKG) – Detects arrhythmias or prior heart attacks
• Echocardiogram – Ultrasound of heart structure and function
• Stress test – Heart performance under exercise conditions
• Blood tests – Cholesterol, blood sugar, C-reactive protein, troponins
• Coronary calcium scan – CT scan to detect early coronary artery disease
• Holter monitor – 24/48-hour tracking of heart rhythm

Lifestyle Modifications

• Prioritize a diet rich in produce, whole grains, and lean sources of protein to support heart health
• Aim for about 30 minutes of moderate physical activity most days of the week
• Maintain a healthy body weight
• Avoid smoking and limit alcohol
• Manage stress and ensure proper sleep

Medical Management

• Medications for blood pressure, cholesterol, or diabetes
• Monitoring and treating arrhythmias
• Interventions such as angioplasty, stenting, or bypass surgery, when necessary

• Schedule regular cardiac check-ups based on your risk profile
• Adopt and maintain healthy lifestyle habits
• Report new symptoms to your doctor without delay

Cardiac screening is a life-saving preventive measure. By detecting issues early and adopting healthier habits, you can reduce your chances of serious complications like heart attacks or strokes.

If you’re at risk, talk to your cardiologist about scheduling a comprehensive heart screening today.
