South Asians face a higher risk of heart disease than many other populations, but understanding the unique factors at play can help reduce that risk. That was the focus of the American Heart Association’s latest Community Conversations on South Asian Heart Health webinar, where Dr. Romit Bhattacharya, a cardiologist at Massachusetts General Hospital and medical director of the OurHealth study, shared insights on heart disease prevention tailored to the South Asian community.
During his presentation, Dr. Bhattacharya addressed a stark reality: while South Asians make up about 25% of the world’s population, they account for 60% of global cardiovascular disease cases. Despite this, they remain underrepresented in cardiovascular research, leaving gaps in understanding their specific risks and needs.
One of the biggest concerns, he explained, is that traditional risk calculators often underestimate cardiovascular disease risk in South Asians. While standard markers such as cholesterol levels, blood pressure, and diabetes are important, they don’t fully capture why South Asians tend to develop heart disease earlier and more aggressively.
The Role of Genetics, Lifestyle, and Misinformation
Dr. Bhattacharya highlighted both genetic predisposition and lifestyle changes as key factors. South Asians often develop high cholesterol and diabetes at younger ages, sometimes without obvious signs like obesity. This means early screening and proactive management are critical, he said.
At the same time, modern lifestyle shifts—less physical activity, more processed foods, and increased urbanization—have amplified health risks. He noted that previous generations benefited from naturally active daily routines and home-cooked meals, while today’s sedentary jobs and convenient, calorie-dense foods have changed the equation.
The session also tackled common myths about heart health. Dr. Bhattacharya debunked the idea that high cholesterol is “normal” if it runs in the family, explaining that while genetics play a role, lifestyle and medication can significantly reduce risk. He also addressed misconceptions about ghee, warning that despite its cultural significance, it remains high in saturated fat, which contributes to plaque buildup in arteries.
Small Changes, Big Impact
The good news, Dr. Bhattacharya emphasized, is that even small lifestyle adjustments can have a major impact on heart health. He encouraged South Asians to:
- Increase physical activity, even with just 10–15 minutes of daily movement
- Swap refined carbs for whole grains and reduce saturated fats
- Prioritize good sleep, which is now recognized as a crucial factor in heart health
- Get screened for cholesterol, blood pressure, and diabetes earlier than guidelines suggest
He also urged South Asians to participate in clinical research to help improve understanding of their unique cardiovascular risks.
The webinar concluded with a Q&A session with Dr. Ami Bhatt, a cardiologist and member of the American Heart Association’s Board of Directors in Greater Boston, where attendees asked about early cholesterol management, the role of statins, and whether South Asians should automatically be placed on cholesterol-lowering medication.
The Community Conversations on South Asian Heart Health series will continue on March 25, with the next session focusing on mental health and its connection to heart disease. Register here.
