The Lancet Global Health, 2018
More than half of cardiovascular deaths in India — 53.4% — occur before the age of 70. In high-income countries cardiovascular disease is predominantly a condition of later life; in India it is substantially a condition of working age. The share of all Indian deaths attributable to cardiovascular causes rose from 15.2% in 1990 to 28.1%, nearly doubling within a single generation. Several factors are implicated: earlier onset of insulin resistance at lower body weights, higher average lipoprotein(a) in South Asian populations, high abdominal obesity prevalence at normal BMI, and screening frameworks calibrated to populations in which the disease arrives a decade later. The practical implication is that risk assessment based on age thresholds imported from Western guidelines will systematically start too late for Indian patients.
GBD India data published in The Lancet Global Health in 2018 found that 53.4% of Indian cardiovascular deaths occur before age 70, a markedly higher proportion than in high-income settings where the burden concentrates after 75.
The same analysis documents the trajectory: cardiovascular disease accounted for 15.2% of all Indian deaths in 1990 and 28.1% by 2016. That is a near-doubling of share within one generation, driven by urbanisation, dietary change and reduced physical activity rather than by any change in genetics.
Several mechanisms operate together. Insulin resistance appears at lower body-mass indices in South Asian populations, so a normal BMI is weaker reassurance. Abdominal obesity — the pattern that matters metabolically — is present in 39.5% of Indian adults. Lipoprotein(a), an inherited and non-modifiable risk factor, runs higher on average in South Asians.
Fatty liver, present in an estimated 38.6% of Indian adults, compounds the picture, and dyslipidaemia is near-universal at 81.2%. None of these produce symptoms in the years when intervention is most effective.
Age-based screening thresholds derived from Western cohorts start roughly a decade too late for this population. If half the cardiovascular deaths occur before 70, a risk assessment beginning at 50 has already missed much of the window in which the trajectory could have been altered.
The markers that move earliest are metabolic rather than lipid: fasting insulin and HOMA-IR shift years before glucose does, and ApoB and Lp(a) describe particle-level cardiovascular risk that a standard cholesterol panel does not capture.
Earlier than Western guidelines suggest. Given that over half of Indian cardiovascular deaths occur before 70 and metabolic dysfunction begins years before it is detectable on a glucose test, many clinicians argue for baseline metabolic and lipoprotein assessment from the thirties, particularly where there is a family history of early heart disease.
No. Insulin resistance and abdominal obesity are both common in Indians at BMIs considered normal by international standards — the "thin outside, fat inside" phenotype. Waist circumference and metabolic markers describe the risk better than BMI does.

The programme
Peak Brain draws a full blood and urine panel at your home, has a licensed physician read every marker together rather than one at a time, and turns what they find into a ranked 90-day protocol with a retest at the end.
