Panel: Genetic predisposition to hypertension

Why it matters

Arterial hypertension can remain asymptomatic for a long time. Persistently elevated blood pressure places additional strain on the blood vessels and heart and, over time, may damage the brain, kidneys and retina. Hypertension is also associated with a higher risk of heart attack, stroke, heart failure and kidney failure. Blood pressure is influenced by lifestyle, age, metabolic health, underlying medical conditions and inherited factors. Genetic testing helps assess inherited characteristics of the mechanisms that control vascular tone and circulation.

The physician interprets the results alongside blood pressure measurements, laboratory tests, family history and other risk factors. This helps determine whether closer monitoring is required and supports an individual approach to cardiovascular disease prevention.

Blood pressure monitoring is particularly important when planning and managing pregnancy. Hypertension is an important risk factor for pre-eclampsia and may be associated with impaired placental blood flow, foetal growth restriction, premature birth and other complications. Information about an inherited tendency towards elevated blood pressure can complement the overall assessment of a woman’s cardiovascular risks when preparing for pregnancy and during antenatal care.

How genetics influences blood pressure

Blood pressure depends on the ability of blood vessels to constrict and relax, the way the body regulates fluid volume and the function of hormonal systems that control circulation. Some of these processes are influenced by genetics. The ACE, AGT and AGTR1 genes are involved in the renin-angiotensin system, which affects vascular tone and fluid and electrolyte balance. NOS3 is responsible for the production of nitric oxide, which is essential for relaxation of the vascular wall. GNB3 is involved in intracellular signal transmission. Analysis of these genes helps assess inherited characteristics of different blood pressure control mechanisms and complements standard cardiovascular diagnostics.

Genetic factors in cardiovascular health

Modern cardiology considers inherited factors as one component of cardiovascular risk. Arterial hypertension may develop through a combination of genetic predisposition, age, lifestyle, dietary habits and metabolic disorders. If hypertension has already been diagnosed, laboratory tests help assess the patient’s current health and identify associated changes. Genetic testing serves a different purpose by providing information about inherited characteristics of the mechanisms involved in blood pressure control. During a consultation with a cardiologist, blood pressure measurements, laboratory test results, medical history and genetic findings are assessed together. This comprehensive approach supports more personalised monitoring, prevention and long-term management of cardiovascular risks.
