Why Indians Must Start Heart Checks in Their 40s

Heart disease in India is often thought of as something, which happens to the old. People who are 60-plus or those having a unhealthy lifestyle with a bad diet and a sedentary life. The father who ignored his blood pressure for a decade. But the research keeps pulling that age younger and a major study published just this year has made the case more clearly than ever that South Asians, including Indians, need to start checking their hearts in their 40s, not their 60s.

This isn't alarmism. It's data. And for a country and a diaspora where cardiovascular disease is already the leading cause of death, often striking people a full decade earlier than their Western counterparts understanding the timeline matters enormously.

Findings Of a New Study

A February 2026 study in the Journal of the American Heart Association revealed that South Asian adults were found to be developing risk factors for heart disease much earlier at mid-40s than white, Black, Chinese and Hispanic adults of the same age.

The health data for over 2700 adults aged 45 to 55 was analyzed by the researchers.1 The subjects were participants in two long-running national studies in the United States. They were participants in the MASALA Study that specifically looks at South Asians of Indian, Pakistani, Bangladeshi, Nepali and Sri Lankan origin.²

The numbers were surprising. At the age of 45, 30.7% South Asian men were prediabetic compared to 3.9% prevalence in comparable aged white men. In other words, nearly eight times more. At the same age, South Asian women had nearly twice the prediabetes prevalence as white, Chinese, Black and Hispanic women.

The blood pressure picture was equally concerning. South Asian men had a significantly higher prevalence of high blood pressure at 45, 25.5%, compared to white men at 18.4% and Chinese men at just 6.6%. For cholesterol and triglycerides, South Asian men were also higher than their Black peers - 78.2% versus 60.6%.

The Paradox

Here's what makes the findings so disquieting: This wasn't a story about an unhealthy population paying the price for poor choices. Despite having higher rates of heart disease risk factors, South Asian adults in the study also had the best quality diet among all groups, lower rates of alcohol use, and comparable physical activity levels.

So the usual explanations don't hold. These aren't people eating badly or living sedentary lives. They are, by measurable standards, living relatively healthier lives than their peers. And yet their heart disease risk factors are appearing earlier and clustering more densely.

There's something deeper behind it. Standard lifestyle advice does not cater for a biological and metabolic vulnerability. Studies have found that the risk of cardiovascular disease in South Asian adults is roughly double than Caucasian adults, while the average clinical presentation occurs at 53 years of age with a higher burden of arterial disease even in the absence of symptoms.

Why South Asians Are Physiologically Different

The excess risk in South Asians is not entirely explained by the usual suspects such as high cholesterol, smoking, obesity. There are several layers to this vulnerability that researchers have been piecing together over decades.

The first factor describes how people develop abdominal fat distribution despite maintaining their weight within normal limits. South Asians exhibit greater abdominal and internal fat accumulation than Western populations because their body mass index remains below the minimum threshold for fat assessment, which creates dangerous metabolic and cardiovascular health risks.

Standard BMI thresholds, which were developed largely on Western populations, miss this risk in South Asians who require screening because their risk matches that of other populations needing evaluation.

The high occurrence rate of insulin resistance together with type 2 diabetes leads to cardiovascular disease through various biological mechanisms which result in multiple body system failures that attack blood vessels and increase blood pressure and damage cholesterol levels and create arterial plaque build-up.

South Asians experience type 2 diabetes at rates, which exceed other ethnic groups by 50 percent while diabetes in this population leads to heart problems which develop at younger ages with more serious conditions.

A 2024 study published in the Journal of the American College of Cardiology added another dimension: South Asians appear to have lower levels of certain stem cells that repair blood vessels after injury. South Asian bodies possess a reduced ability to heal cardiovascular damage which leads to faster disease progression with more severe symptoms.³

The Screening Gap

Despite all of this evidence, South Asians are still largely screened for cardiovascular risk on the same timelines as everyone else. The standard recommendation to begin regular heart health checks in the 50s or later means South Asians are potentially missing a decade of intervention opportunity.

Senior study author Professor Namratha Kandula of Northwestern University said: "The earlier accumulation of health conditions that increase the chance of heart disease among South Asian adults signals the need for earlier screening, tailored prevention and prompt risk-factor management. If you are a South Asian adult, maintain a healthy lifestyle and get screened sooner, check blood pressure, glucose and cholesterol in early adulthood rather than waiting for symptoms."

This is the key shift that the research is pushing for. Not just knowing that the risk is higher, but acting on it years earlier than current guidelines suggest.

What Should You Do

The practical takeaway from all of this research is a recalibration of when to start paying attention and what to monitor.  

Blood pressure, blood glucose, and cholesterol should be checked from the late 30s for South Asians, rather than the mid-50s that general population guidelines often suggest.

The A1C test , which measures average blood sugar over three months and is a better predictor of prediabetes risk than a single fasting glucose reading, deserves particular attention given the dramatically elevated prediabetes rates found in the study.

 Waist circumference is a more meaningful indicator than body weight alone for South Asians. A person who looks lean by standard weight measures may be carrying metabolic risk in their abdominal profile that doesn't show up on a standard BMI calculation.

Indian and South Asian-specific BMI thresholds set lower than international standards exist for exactly this reason and are worth using.

Family history matters significantly. If a parent, uncle, or sibling has had a heart attack or been diagnosed with diabetes before age 55, the urgency of early screening escalates further.

The Risk is Embedded in Biology

Heart disease in South Asian communities often goes undiscussed until it becomes a crisis a sudden heart attack, a hospitalization, a death that comes too soon. Part of what drives this silence is the belief that heart disease is a consequence of obvious bad habits, and if someone isn't visibly overweight or obviously unhealthy, there's nothing to worry about.

The science says otherwise. The risk is embedded in the biology, in the metabolic tendencies that come with South Asian ancestry, and it begins accumulating earlier than families typically realize. Knowing that , and getting screened accordingly is the most straightforward intervention available.
