Looking Beyond Lifestyle: Understanding Inherited Heart Risk

Heart disease does not always result from lifestyle choices alone. Family history and inherited factors can influence cardiovascular risk, sometimes even when cholesterol levels and other routine health measurements appear normal.

How does family history influence heart risk?

A family history of early cardiovascular disease can indicate an increased risk. Having a first-degree relative — a parent or sibling — who developed cardiovascular disease before age 55 in men or 65 in women is recognized as a cardiovascular risk-enhancing factor [1].

This association may reflect inherited tendencies towards high cholesterol, high blood pressure, diabetes, and other risk factors, alongside shared lifestyle habits. Family history does not mean heart disease is inevitable, but it can help identify people who may benefit from earlier risk assessment and preventive care.

What is Lipoprotein(a) [Lp(a)]?

Lipoprotein(a), or Lp(a), is a cholesterol-carrying particle in the blood that resembles LDL cholesterol but contains an additional protein called apolipoprotein(a). Its level is largely determined by genetics, and elevated Lp(a) is associated with an increased risk of atherosclerotic cardiovascular disease, including heart attack and stroke [2].

Importantly, Lp(a) can be elevated even when LDL cholesterol is within the recommended range. This means a routine lipid profile may not reveal the full picture of inherited cardiovascular risk.

Why should you consider Lp(a) testing?

Lp(a) is particularly relevant for people with a family history of premature heart disease or known elevated Lp(a). Major cardiovascular guidelines identify levels of 50 mg/dL or 125 nmol/L and above as a risk-enhancing factor [1, 2]. These units are not directly interchangeable using a single fixed conversion.

Because Lp(a) levels are largely inherited and generally remain relatively stable throughout life, measuring them can help identify an additional risk factor that may otherwise go unnoticed. A healthcare professional can advise whether testing is appropriate and how the result should be interpreted alongside other risk factors.

Understand your inherited risk. Take informed action.

Family history and Lp(a) are important pieces of the cardiovascular risk picture, but neither determines an individual’s future on its own. Understanding them alongside blood pressure, cholesterol, blood sugar, lifestyle and medical history can help guide a more informed prevention plan.

HeartIQ Score Application, developed by leading cardiologists in Kerala, brings together relevant health history, lifestyle factors and blood biomarkers, including Lipoprotein(a) [Lp(a)], to support cardiovascular risk assessment. By connecting risk assessment with online doctor consultations and personalized guidance, HeartIQ Score helps users better understand their cardiovascular risk and make informed decisions about preventive care.

From risk assessment to informed action — a pathway to better understand your heart health and take appropriate preventive steps.
