Cardiac screening can help detect heart disease early.
Heart disease remains the leading cause of death worldwide, but many cases can be prevented with early detection and lifestyle changes. Our cardiology team explains what you need to know to protect your heart health.
Understanding Heart Disease
Heart disease refers to several types of heart conditions, with coronary artery disease being the most common. This occurs when the arteries that supply blood to the heart become hardened and narrowed due to plaque buildup (atherosclerosis).
Key Fact
About 80% of premature heart disease and stroke can be prevented through healthy lifestyle behaviors.
Warning Signs to Watch For
Many people don't experience symptoms until they have a heart attack or other serious event. However, some early warning signs include:
- Chest pain or discomfort (angina)
- Shortness of breath
- Pain, numbness, or coldness in legs/arms
- Pain in neck, jaw, throat, upper abdomen or back
- Fatigue, lightheadedness or dizziness
Risk Factors
Some risk factors for heart disease can't be changed, but many can be managed:
Non-Modifiable Risks
- Age (men over 45, women over 55)
- Family history of heart disease
- Post-menopausal status
Modifiable Risks
- High blood pressure
- High cholesterol
- Smoking
- Diabetes
- Obesity and physical inactivity
Prevention Strategies
Our cardiology team recommends these evidence-based strategies to reduce your risk:
1. Know Your Numbers
Regular check-ups to monitor blood pressure, cholesterol levels, and blood sugar are essential. Adults should have these checked:
- Blood pressure: At least every 2 years if normal
- Cholesterol: Every 4-6 years for adults 20+
- Blood sugar: Starting at age 45, or earlier if overweight
2. Adopt Heart-Healthy Eating
The Mediterranean diet has been shown to reduce heart disease risk by 30%. Focus on:
- Plenty of vegetables, fruits, and whole grains
- Healthy fats like olive oil and nuts
- Lean proteins including fish and poultry
- Limiting red meat, sugar, and processed foods
When to See a Cardiologist
Consider scheduling a cardiology consultation if you:
- Have a family history of heart disease
- Experience chest pain or shortness of breath
- Have multiple risk factors (high BP, cholesterol, etc.)
- Are planning to start an exercise program after being sedentary
3. Get Regular Exercise
Aim for at least 150 minutes of moderate-intensity exercise weekly. Even short bouts of activity provide benefits. Our cardiac rehab team recommends:
- Brisk walking (3-4 mph)
- Swimming or water aerobics
- Cycling (stationary or outdoor)
- Strength training 2x/week
4. Manage Stress
Chronic stress may contribute to heart disease risk. Effective stress management techniques include:
- Mindfulness meditation
- Deep breathing exercises
- Regular physical activity
- Adequate sleep (7-9 hours nightly)
Diagnostic Tests
If heart disease is suspected, your doctor may recommend one or more of these tests:
| Test | Purpose |
|---|---|
| Electrocardiogram (ECG) | Records electrical signals in your heart |
| Echocardiogram | Ultrasound of your heart's structure and function |
| Stress Test | Measures heart function during exercise |
| Cardiac Catheterization | Checks for blocked arteries |
Treatment Options
Treatment depends on the type and severity of heart disease but may include:
- Lifestyle changes: Diet, exercise, smoking cessation
- Medications: To control risk factors or symptoms
- Medical procedures: Angioplasty, stenting, bypass surgery
- Cardiac rehabilitation: Supervised exercise and education
