Diabetes, particularly Type 2 diabetes (also known as maturity onset diabetes), is a prevalent medical condition with a significant impact on cardiovascular health. According to the recent ICMR-INDIAB-17 study published in The Lancet in 2023, the prevalence of Type 2 diabetes in India is around 11.4%, reflecting a broader global trend where diabetes affects approximately 100 million people in the country, making it the second most affected after China. The impact of diabetes on cardiovascular health is profound, as it considerably increases the risk of heart disease and stroke, even when glucose levels are well managed.
The Link Between Diabetes and Cardiovascular Disease
Increased Risk of Heart Disease
Diabetes elevates the risk of heart disease significantly. For individuals with Type 2 diabetes, the risk of experiencing a heart attack within ten years is approximately 20%. This risk is compounded by a phenomenon known as a “silent heart attack,” which occurs because diabetes can impair the nerves responsible for transmitting pain. As a result, individuals with diabetes may not experience the typical pain associated with a heart attack, making the condition more dangerous and difficult to diagnose.
Hypertension
High blood pressure (hypertension) is a major risk factor for cardiovascular disease and stroke. It often coexists with insulin resistance, a key factor in diabetes development. The combination of hypertension and diabetes further amplifies the risk of cardiovascular complications. Managing blood pressure effectively is crucial for reducing cardiovascular risk in diabetic patients.
Cholesterol and Triglycerides
Diabetes often disrupts cholesterol and triglyceride levels, leading to abnormal lipid profiles. Common issues include high levels of LDL (“bad”) cholesterol, low levels of HDL (“good”) cholesterol, and elevated triglycerides. This lipid imbalance, known as diabetic dyslipidemia or atherogenic dyslipidemia, contributes to the early onset of heart attacks and is closely linked with insulin resistance.
Obesity
Obesity is a significant risk factor for cardiovascular disease (CVD) and is strongly associated with insulin resistance. Excess weight can exacerbate the risk of developing heart disease by increasing insulin levels and decreasing insulin sensitivity. Weight loss is a key strategy for improving cardiovascular health, managing insulin levels, and reducing overall CVD risk.
Sedentary Lifestyle
Physical inactivity is another modifiable risk factor for both insulin resistance and cardiovascular disease. Regular physical activity, including moderate to vigorous exercises, can prevent or delay the onset of Type 2 diabetes, reduce blood pressure, and lower the risk of heart attack and stroke. Recommendations include at least 8,000 steps per day or engaging in other forms of exercise at least five days a week.
Poor Blood Sugar Control
Uncontrolled diabetes can lead to elevated blood sugar levels, which are harmful to blood vessels and the heart. Maintaining blood sugar levels within a healthy range is essential for minimizing cardiovascular risk and preventing long-term complications.
Smoking
Smoking significantly increases the risk of heart disease and stroke, compounding the cardiovascular risks associated with diabetes. Diabetic individuals who smoke face an even higher risk of cardiovascular events.
Managing Risk Factors
Effective management of diabetes and associated risk factors is crucial for preventing heart disease and related complications. Individuals with diabetes, especially those with additional risk factors such as hypertension, high cholesterol, or obesity, should work closely with their healthcare providers to monitor and control these factors.
Regular testing for cardiovascular risk factors, including blood pressure, cholesterol levels, and weight, is essential for early diagnosis and treatment. Addressing these risk factors proactively can help prevent or delay the onset of heart disease, stroke, chronic kidney disease, and other serious complications.
Conclusion
The association between diabetes and cardiovascular disease underscores the importance of comprehensive management of diabetes and its related risk factors. By addressing issues such as hypertension, abnormal cholesterol levels, obesity, physical inactivity, poor blood sugar control, and smoking, individuals with diabetes can significantly reduce their risk of heart disease and stroke. Early diagnosis and effective treatment are key to improving overall health outcomes and preventing serious cardiovascular complications.
