What Is Coronary Artery Disease (CAD)?

Coronary Artery Disease (CAD) is one of the leading causes of death in both men and women. It occurs when cholesterol-rich plaques accumulate along the inner lining of the coronary arteries—the blood vessels responsible for supplying oxygen to the heart muscle. As these plaques grow, blood flow is reduced, depriving the heart of oxygen and leading to chest pain (angina), heart attack, heart failure, abnormal heart rhythms (arrhythmias), or sudden cardiac death.

Although women typically develop CAD about 10 years later than men, it remains the number one killer of women. Younger women are particularly prone to coronary microvascular disease, where the smaller blood vessels of the heart are affected even without major cholesterol blockages. A decline in estrogen levels after menopause, combined with traditional risk factors, is believed to contribute to this condition.

Despite overall reductions in heart disease–related deaths over recent decades, the decline has been significantly less in women. Conditions such as coronary microvascular disease and stress-induced cardiomyopathy (broken heart syndrome) are more common in women than in men.

A major reason for poorer outcomes is lack of awareness. Many women ignore early warning signs due to family or work responsibilities and seek medical care only when symptoms become severe.

Risk Factors for Coronary Artery Disease

Risk factors are conditions or behaviors that increase the likelihood of developing heart disease or having a heart attack. The good news is that many of these factors can be controlled or modified.

Modifiable (Controllable) Risk Factors

• High blood pressure (Hypertension)
• Diabetes
• Smoking
• High cholesterol (Dyslipidemia)
• Obesity
• Physical inactivity
• Chronic stress
• Alcohol consumption

Non-Modifiable (Uncontrollable) Risk Factors

• Increasing age
• Female gender
• Family history of heart disease

Broken Heart Syndrome (Stress Cardiomyopathy)

Women are more susceptible to this condition, where intense emotional or physical stress can suddenly weaken the heart muscle. This condition, also known as Takotsubo cardiomyopathy, mimics a heart attack but is usually reversible with prompt care.

Women-Specific Risk Factors

Certain conditions unique to women can further increase heart disease risk:

• Menopause and hormonal changes
• Use of hormonal or birth control pills (especially in women over 35 who smoke or have a strong family history of CAD)
• Pregnancy-related complications such as gestational diabetes and preeclampsia
• Autoimmune diseases like lupus and rheumatoid arthritis

After menopause, the risk of heart disease rises significantly, likely due to hormonal changes, though the exact mechanism is not fully understood.

Symptoms of Coronary Artery Disease in Women

Recognizing symptoms early is critical to saving lives. Women often experience atypical symptoms, which makes diagnosis more challenging.

Common Symptoms

• Chest discomfort: pressure, heaviness, burning, or uneasiness
• Pain in the arms, neck, jaw, or teeth
• Shortness of breath
• Excessive sweating
• Rapid or irregular heartbeat
• Lightheadedness or dizziness
• Symptoms that worsen with walking or physical activity
• Recurrent or persistent discomfort
• Nausea, stomach pain, or vomiting

Because symptoms may not resemble classic chest pain, many women mistakenly ignore them.

Reducing the Risk of Heart Disease

Healthy Lifestyle Measures

• Follow a heart-healthy diet
• Engage in regular physical activity
• Maintain a healthy body weight
• Avoid smoking and alcohol
• Manage stress effectively
• Undergo regular health check-ups

Ideal body weight can be roughly estimated as:
Height (in cm) − 100

Healthy Diet Recommendations

• Eat plenty of fruits and vegetables
• Choose whole grains and high-fiber foods
• Include omega-3 rich foods such as fish, nuts, flax seeds, and olive oil
• Use healthy oils (sunflower, olive, rice bran, canola, gingelly)
• Limit oil intake to 500 ml per person per month
• Choose lean protein: skinless chicken, egg whites
• Reduce salt, sugar, and refined grains (maida)

Avoid

• Red meat (mutton, beef, pork)
• Deep-fried foods
• Bakery and processed foods
• Ghee, butter, cheese
• Coconut and coconut oil
• Foods high in saturated and trans fats

Physical Activity

• Walk briskly for 30–40 minutes daily
• Exercise helps:
  • Lower cholesterol and increase good cholesterol (HDL)
  • Control blood pressure and blood sugar
  • Maintain ideal body weight
  • Reduce dependency on medications

Smoking and Stress

• One in five deaths is linked to smoking
• Smoking is the leading preventable cause of death and damages every organ
• Chronic stress from family or workplace conflicts increases heart attack risk
• Stress management techniques include meditation, yoga, music, and reading

Prevention and Health Monitoring

• Health check-ups:
  • Every 2 years after age 30
  • Annually after age 40
• Maintain blood pressure below 140/80 mmHg
• Diabetics should monitor blood sugar regularly, including fasting blood sugar (FBS)

Treatment of Coronary Artery Disease

Advancements in heart care have significantly improved survival rates. If a patient reaches the hospital within the first hour of a heart attack, the blocked artery can often be opened using Primary Angioplasty.

Unfortunately, many patients delay seeking care, assuming symptoms are due to gas or indigestion. Any chest discomfort should be treated as an emergency. Immediate evaluation with an ECG is essential.

If you or a family member experiences symptoms suggestive of a heart attack, seek immediate care from experienced heart specialists at VishwaRaj Hospital. While effective treatments are available, prevention remains the most powerful strategy in reducing heart disease in women.
