Cardiovascular Health for Men Over 40
From the mid-thirties to the early forties, the cardiovascular risk profile in men shifts gradually. Blood pressure, fasting blood glucose, and cholesterol often rise imperceptibly – without noticeable symptoms. At the same time, testosterone levels slowly decline, abdominal fat increases, and vascular elasticity decreases. These changes are not random and not an inevitable fate. They are biologically well understood – and to a considerable degree modifiable.
What changes in the heart from age 40
Cardiovascular disease is the leading cause of death in men in Western countries. The risk rises markedly with age, but the critical juncture occurs earlier – in the years between 40 and 55.
Blood vessels and blood pressure
With increasing age, arterial walls lose elasticity. Collagen progressively replaces elastic fibres, and vascular stiffness increases. The result: systolic blood pressure rises and the heart must work against greater resistance. At the same time, sustained elevated blood pressure promotes atherosclerotic deposits – a mutually reinforcing process that builds over years, long before any symptoms become perceptible.
A review in the journal JACC (2024) shows that cardiovascular changes due to biological ageing processes are measurable from the fourth decade of life onwards, long before clinical symptoms appear.
Lipids and metabolism
The ratio of LDL to HDL deteriorates in many men from age 40 – often driven by reduced physical activity, altered caloric expenditure, and metabolic shifts. Elevated triglycerides, which frequently accompany increasing waist circumference and insulin resistance, are recognised as an independent cardiovascular risk factor. A meta-analysis in the European Heart Journal (2024) also shows that awareness of one’s personal cardiac risk value significantly improves readiness for lifestyle change and actual risk reduction.
Body weight and visceral fat
Abdominal fat is metabolically active. It produces pro-inflammatory cytokines, influences insulin sensitivity, and raises blood pressure. Waist circumference is now considered a more meaningful risk indicator than body weight alone. A waist circumference above 94 cm is associated with elevated cardiovascular risk in men – regardless of BMI.
From the clinic: Markus, 47, site manager: For a few weeks he has been experiencing a pressure sensation in his chest when climbing stairs quickly, which sometimes radiates into his left arm. He ignores it at first. BMI 29, smoker for 20 years, his father had a heart attack at 52. His GP orders an ECG, which shows signs of insufficient blood supply to the heart — an indication that the heart is not getting enough oxygen under exertion. Markus is referred directly to hospital. There, an examination of the coronary vessels reveals a narrowing in one of the heart's arteries, which can be successfully widened. Markus was fortunate that he finally told his GP about his symptoms.
What the evidence clearly shows
Exercise
Physical activity is the single most effective measure for cardiovascular prevention. A large meta-analysis of over 103 studies (International Journal of Behavioral Nutrition and Physical Activity, 2024) shows: regular leisure-time physical activity reduces the risk of cardiovascular disease, coronary heart disease, and stroke by around one fifth compared with physical inactivity. The effect is dose-dependent – even moderate amounts help, and the first step is the most important.
Particularly effective is the combination of endurance training – around 150 minutes of moderate intensity per week – and twice-weekly strength training. The latter improves insulin sensitivity, reduces visceral fat, and has a positive effect on blood pressure. Together, both are more than the sum of their parts.
Nutrition
The PREDIMED trial, one of the largest randomised dietary studies on cardiac health, shows: a Mediterranean diet reduces major cardiovascular events – heart attack, stroke, cardiovascular death – by nearly half compared with a low-fat diet. A 2024 meta-analysis of over 10,000 participants confirms this effect. Mediterranean nutrition means: plenty of vegetables, legumes, olive oil, and fish, with little red meat and processed foods.
Statins and medical prevention
According to current prevention guidelines, statin therapy for primary prevention can be recommended in men between 40 and 75 years of age with an estimated 10-year cardiac risk above ten percent. The decision depends on the individual risk profile – age, blood pressure, cholesterol, smoking status, and diabetes risk are incorporated into standardised risk calculators. This decision should be made together with a doctor who knows the personal risk profile.
Risk factors you should know
An elevated cardiovascular risk from age 40 is often the sum of several individually moderate factors. No single factor causes symptoms in the short term – but their combined effect over years is the primary driver of heart attack and stroke. These include high blood pressure (systolic above 130 mmHg or diastolic above 80 mmHg), elevated LDL cholesterol, fasting blood glucose above 100 mg/dl as a precursor to diabetes, a waist circumference above 94 cm, smoking, physical inactivity, a family history of heart disease (heart attack in father or brother before age 55), and sleep apnoea – a substantially underestimated risk factor that is frequently overlooked.
What you can do in everyday life
- • Know your risk profile: Blood pressure, fasting blood glucose, cholesterol, and waist circumference should be checked regularly from age 40 – at least every two years, and annually if anything is abnormal.
- •Exercise with structure: At least 150 minutes of moderate endurance activity per week plus twice-weekly strength training. Brisk walking counts.
- •Adjust your diet: Mediterranean nutrition as a guiding principle – more vegetables, legumes, and olive oil, less processed food and red meat.
- •Keep an eye on waist circumference: Visceral fat responds well to the combination of exercise and dietary change – and is a more important indicator than body weight alone.
- •Take sleep seriously: Poor sleep raises cortisol and blood pressure on a sustained basis. If you snore and feel persistently exhausted despite sufficient sleep, sleep apnoea should be ruled out.
