Heart Health Month

Cardiovascular disease is the biggest killer

February is American Heart Health Month.

Valeria Hegnauer, Nadiia Wyttenbach and Bracy Fertig take this opportunity to call attention to a reality that remains widely misunderstood: heart disease is the leading cause of death across both genders. 

Nadiia Wyttenbach completed her PhD on the molecular mechanisms of obesity and metabolic disorders. Bracy Fertig investigated cardiovascular health during her research doctorate. 

As molecular doctors, they are repeatedly struck by how unaware society remains of how deadly - yet largely manageable - this condition truly is.

Heart disease kills women at equal or higher rates than men

Yes, you are reading this correctly.

Using World Health Organization Global Health Estimates and aggregating mortality data across Europe and the United States over the past decade, cardiovascular illness accounts for 36% of all male deaths and 44% of all female deaths.

Let that sink in.

Nearly 1 in 2 female deaths are attributable to cardiovascular factors (not only heart disease, but also stroke and other cardiovascular conditions). No other risk factors come even close. 

The European contribution is particularly strong, with nearly 50% of female deaths in the region attributable to cardiovascular disease. In the US, cardiovascular mortality is slightly less dominant, although it is the leading cause of death. This difference is explained by shorter life expectancy in the United States and a more fragmented distribution of causes of death at younger ages, including more accidents, kidney failure largely driven by higher obesity rates, and a higher proportion of dementia-related deaths.

For many, these figures come as a shock. We are conditioned to believe that this is primarily a male disease. That assumption is simply wrong.

Cancer rightly commands attention and fear. Dementia is also widely discussed, particularly in women. Both concerns are valid. Yet the sheer magnitude of mortality driven by heart-related causes is staggering - and it receives nowhere near the same level of awareness, prevention, or early intervention.

Another uncomfortable truth: heart disease does not merely lead - it overwhelms every other major disease category, including cancer.

Why heart disease is so deadly: it kills silently and slowly, over decades

This condition is rarely sudden. It is usually the result of a slow, multi-decade process that unfolds quietly, frequently in connection to metabolic dysfunction: excess weight, elevated blood pressure, insulin resistance, abnormal lipids and cholesterol.

Symptoms often emerge late, once significant damage has already occurred.

High blood pressure alone can progress for years without obvious warning signs, while steadily harming blood vessels, kidneys, the heart itself. By the time a formal diagnosis is made, prevention has often given way to long-term management.

This long latency explains why mortality is so abrupt.

The female risk factor

In women, cardiovascular disease remains under-recognized, under-diagnosed, and under-treated - especially in early adulthood and midlife. When elevated blood pressure or pre-diabetes is finally identified, years or even decades of silent damage have often already taken place.

Cancer awareness campaigns have been effective. Cardiometabolic risk awareness, particularly for women, has not kept pace.

A multi-factorial disease

Sometimes, even patients who did everything right - ate well, exercised, and maintained a healthy lifestyle - still develop this illness. The disease is multifactorial, shaped by genetic predisposition, individual biological variation, and coexisting conditions. 

Hence, study your family history of all illnesses, and talk to your doctor early. 

That said, an unhealthy lifestyle, particularly physical inactivity, significantly increases the risk of cardiovascular events. Population-level studies suggest that exercise is one of the most effective protective tools for women in particular, yet there is a concerning trend of women exercising less than men.

Reduce your risk today

The most striking aspect of heart disease is not its scale, but how manageable it could have been for many patients.

Intense physical activity, alongside a healthy diet, is one of the most powerful interventions available. Evidence suggests that women may benefit even more than men from consistent exercise.

Maintaining a healthy weight, avoiding smoking, moderating alcohol consumption, managing blood pressure, and addressing metabolic risk early can materially change long-term outcomes.

Muscle mass - especially in large muscle groups - plays a critical role in metabolic regulation. Think of muscles as a sponge for blood sugar and lipids. Strength training is not optional. Lifting weights and training large muscles such as the quadriceps through full-body workouts delivers meaningful benefits. Do all kinds of exercise – weights, cardio, coordination. However, if you must choose, choose weights workout. 

For some individuals, genetic predisposition places them at exceptionally high risk—sometimes from early adulthood or even childhood. Understanding your family history of metabolic and cardiovascular conditions is therefore critical. Discuss it openly with your physician, commit to regular check-ups, and take medical guidance seriously.

With the rollout of effective weight-loss and anti-obesity therapies, including semaglutide and dual-receptor agonists, patients now have more tools than ever to reach a healthy weight and achieve meaningful cardiovascular benefits.

Heart disease remains the dominant cause of death in advanced economies, by a wide margin.

For policymakers, healthcare systems, investors, and individuals alike, the implication is clear: prevention and early intervention offer the single greatest opportunity to reduce mortality and long-term healthcare burden.

Your health cannot wait.
