After 20 years of practicing cardiology, I've seen firsthand how heart disease affects families and communities. What strikes me most is that so many cases could have been prevented with the right knowledge and early action. I want to share what I've learned from treating thousands of patients and what I wish everyone knew about protecting their heart health.
What I've Learned About Heart Disease
Heart disease isn't just one condition—it's a family of problems that can affect your heart and blood vessels in different ways. As the leading cause of death worldwide, it touches almost every family, but here's what gives me hope: most forms are preventable, and when caught early, they're highly treatable.
I've seen patients in their 30s with advanced heart disease and patients in their 80s with hearts that look like they belong to someone decades younger. The difference often comes down to lifestyle choices and early intervention.
Why This Matters to Me
These statistics always hit close to home: heart disease is the leading cause of death globally, affecting both men and women. But what gives me hope is that many risk factors are within our control, and early detection truly can save lives. I've seen it happen time and time again in my practice.
Types of Heart Disease
Coronary Artery Disease (CAD)
- Most common type of heart disease
- Occurs when arteries become narrowed or blocked
- Can lead to heart attack
- Often caused by atherosclerosis
Heart Attack (Myocardial Infarction)
- Occurs when blood flow to heart is blocked
- Can cause permanent heart damage
- Requires immediate medical attention
- Survival depends on quick treatment
Heart Failure
- Heart cannot pump blood effectively
- Can be acute or chronic
- Leads to fluid buildup in body
- Requires ongoing management
Arrhythmias
- Irregular heart rhythms
- Can be too fast, too slow, or irregular
- Some are harmless, others life-threatening
- May require medication or devices
Valvular Heart Disease
- Problems with heart valves
- Can be congenital or acquired
- May require surgery
- Can lead to heart failure
Risk Factors
Non-modifiable Risk Factors
- Age (risk increases with age)
- Gender (men at higher risk, women after menopause)
- Family history of heart disease

- High cholesterol
- Diabetes
- Smoking
- Obesity
- Physical inactivity
- Poor diet
