Diabetes is a chronic condition that affects millions of people worldwide, but its impact on heart health is often underestimated. High blood sugar levels can lead to serious cardiovascular complications, increasing the risk of heart attacks, strokes, and other heart diseases. Dr. Tanmai Yermal, a leading Consultant Interventional Cardiologist in Kharadi, Pune, explains the connection between diabetes and heart disease and provides essential strategies to prevent complications.
How Does Diabetes Affect Heart Health?
Diabetes significantly increases the risk of developing heart-related conditions. Here’s how:
1. Increased Risk of Atherosclerosis
High blood sugar levels can damage blood vessels over time, leading to the buildup of fatty deposits (plaque) in the arteries. This condition, called atherosclerosis, narrows the arteries and restricts blood flow to the heart, increasing the risk of heart attacks and strokes.
2. High Blood Pressure and Cholesterol
People with diabetes are more likely to have high blood pressure (hypertension) and abnormal cholesterol levels, both of which contribute to heart disease. Elevated LDL ("bad") cholesterol and decreased HDL ("good") cholesterol further accelerate plaque formation in the arteries.
3. Increased Risk of Heart Failure
Diabetes can weaken the heart muscle, making it harder for the heart to pump blood effectively. This condition, known as heart failure, leads to symptoms like shortness of breath, fatigue, and swelling in the legs.
4. Damage to Small Blood Vessels (Diabetic Cardiomyopathy)
Apart from affecting large arteries, diabetes also damages the tiny blood vessels that supply oxygen and nutrients to the heart muscle. This can lead to diabetic cardiomyopathy, a condition that increases the risk of heart failure.
Warning Signs of Heart Problems in Diabetic Patients
People with diabetes often have silent heart disease, meaning they may not experience typical symptoms like chest pain. Instead, they may notice:
- Shortness of breath
- Fatigue or weakness
- Swelling in the legs or ankles
- Irregular heartbeat
- Dizziness or fainting
If you experience any of these symptoms, consult a cardiologist immediately.
Ways to Prevent Heart Complications in Diabetics
Managing diabetes effectively can reduce the risk of heart disease. Here are some essential steps to protect your heart:
1. Control Blood Sugar Levels
Keeping blood sugar levels within the target range helps prevent damage to blood vessels. Regular monitoring and following a prescribed diabetes treatment plan are crucial.
2. Maintain Healthy Blood Pressure and Cholesterol
- Aim for a blood pressure below 130/80 mmHg
- Keep LDL cholesterol low and HDL cholesterol high
- Follow a heart-healthy diet rich in fiber, vegetables, and lean proteins
3. Adopt a Heart-Healthy Diet
A diabetes-friendly diet also benefits heart health. Focus on:
- High-fiber foods like whole grains, fruits, and vegetables
- Lean proteins such as fish, chicken, and legumes
- Healthy fats from nuts, seeds, and olive oil
- Limiting sugar, salt, and processed foods
4. Exercise Regularly
Physical activity improves blood sugar control and heart health.
- 150 minutes of moderate exercise per week (like brisk walking or cycling)
- Strength training twice a week
- Avoid prolonged sitting—stay active throughout the day
5. Quit Smoking and Limit Alcohol
- Smoking damages blood vessels and worsens diabetes complications
- Alcohol can raise blood sugar and blood pressure, increasing heart disease risk
6. Manage Stress and Get Enough Sleep
- Chronic stress increases blood sugar and blood pressure
- Practice meditation, deep breathing, or yoga to reduce stress
- 7-8 hours of quality sleep helps regulate heart and metabolic health
7. Take Medications as Prescribed
- Medications for diabetes, blood pressure, and cholesterol help prevent complications
- Follow doctor’s advice on aspirin or other heart-protective drugs
Regular Heart Checkups for Diabetic Patients
Diabetes increases the risk of silent heart disease, making regular cardiovascular checkups essential. Dr. Tanmai Yermal recommends:
- Annual cholesterol and blood pressure checks
- ECG (Electrocardiogram) and stress tests if symptoms arise
- Echocardiography to check heart function
- Coronary angiography if high-risk factors are present
Diabetes and heart disease are closely linked, but proper management can prevent serious complications. By controlling blood sugar, adopting a heart-healthy lifestyle, and undergoing regular heart checkups, individuals with diabetes can significantly reduce their risk of heart problems. Under the guidance of an experienced interventional cardiologist like Dr. Tanmai Yermal, you can take proactive steps toward a healthier heart and a better quality of life.
