While numerous factors can contribute to elevated blood pressure, a comprehensive review of studies conducted in 2018 reveals that hereditary elements may exert an influence of around 20 to 55 percent. Several of the genes associated with a predisposition to high blood pressure, heart disease, or stroke tend to be shared among individuals with blood relations. This article will explore steps to take if you have a familial history of heart disease, aiming to foster a lengthy and robust cardiovascular well-being.


Commencing with the fundamentals, high blood pressure presents a potentially life-threatening condition that can detrimentally affect the heart. On a global scale, this condition impacts approximately 1 billion individuals. Left unaddressed, high blood pressure escalates the likelihood of encountering heart disease and stroke.

In terms of global mortality, heart disease stands as the foremost cause. The umbrella term “heart disease” encompasses a range of cardiac disorders, each characterized by distinct symptoms and necessitating specific courses of action.

Understanding the significance of knowing your family history is crucial. High blood pressure frequently has a hereditary component, with an escalated risk for individuals whose parents are affected by it, particularly if both parents have the condition.

If there’s a blood relation, like a mother, father, sibling, or brother, who experienced high blood pressure before turning 60, you possess a family history of the condition. The intensity of the family history of high blood pressure becomes more pronounced with a higher count of family members encountering high blood pressure before reaching 60 years of age.

However, it’s important to grasp that having a family history of high blood pressure doesn’t definitively predict your own likelihood of developing it, but it does heighten your susceptibility.

Additionally, other risk factors for heart disease and stroke encompass elevated cholesterol levels, increased body fat, and heightened sensitivity to the blood pressure-elevating effects of salt. These factors can elevate your risk of future heart disease and stroke, irrespective of whether you currently have high blood pressure.

To assess your risk:

  1. Compile a list of family members.
  2. Initiate with immediate relatives such as parents, siblings, and, if desired, extend to more distant relatives like grandparents, aunts, and uncles.

What will I do if I have a Family history of heart disease

Keep a close watch on your blood pressure from the comfort of your home. Monitoring your blood pressure is the sole method to determine if you have high blood pressure. The onset of high blood pressure is often gradual, displaying no immediate warning signs or symptoms, which means many individuals remain unaware of their condition.

Taking blood pressure tests at home is also recommended. Tests conducted in a medical setting can be influenced by external factors like the stress of commuting and the anxiety associated with waiting at the doctor’s office. Home-based tests tend to be more relaxed and precise.

Cease smoking
Substantial evidence underscores the conclusion that cigarette smoking triggers a range of unfavorable cardiovascular events, and when combined with hypertension and dyslipidemia, it amplifies the risk of coronary heart disease.

Smoking leads to a swift surge in blood pressure and heart rate, and it’s linked to severe hypertension. The nicotine within cigarettes acts as an adrenergic agonist, inducing the release of local and systemic catecholamines and potentially vasopressin. These substances harm blood vessel walls, fostering atherosclerosis where arterial walls accumulate fat, causing narrowing. Smoking also heightens the likelihood of blood clotting and compels the heart to work more strenuously.

Moderate alcohol consumption
Excessive alcohol intake can elevate blood pressure to unhealthy levels. Consuming more than three drinks in a single session temporarily increases blood pressure, but repetitive episodes of binge drinking can lead to sustained elevations.

Alcohol triggers higher levels of the hormone renin in the bloodstream, causing blood vessels to constrict, resulting in a reduced diameter. Renin also reduces the body’s fluid elimination via urine. This combination of increased bodily fluid levels and narrowed blood vessels contributes to heightened blood pressure.

If possible, consider abstaining from alcohol, especially given your heightened risk of high blood pressure. Individuals with a family history of high blood pressure are more likely to experience detrimental health effects from alcohol consumption compared to those without such a history.

Reduce dietary sodium (salt) intake
Salt prompts the body to retain water. Overconsumption of sodium leads to excess water in the bloodstream, creating additional pressure on blood vessel walls and subsequently raising blood pressure.

Even a slight reduction in dietary sodium can yield heart health improvements and lower high blood pressure by approximately 5 to 6 mm Hg. The impact of sodium intake on blood pressure is particularly notable for individuals genetically predisposed to high blood pressure. As a general guideline, aim to restrict sodium intake to about one teaspoon per day or less.

To diminish sodium in your diet, opt for home-cooked meals. Preparing your own food allows you to regulate the quantity of salt in your dishes.

Adopt a nutritious diet
Although blood pressure-lowering medications are often effective, they might not address the root cause of the issue. Furthermore, regardless of their safety profile, all medications can potentially lead to undesired or unintended side effects.

Embracing a healthful diet serves as a robust initial approach to shield against high blood pressure. It proves to be an excellent primary strategy when blood pressure edges into unhealthy territory and complements medication effectively. Consuming a diet abundant in whole grains, fruits, vegetables, and low-fat dairy products, while minimizing saturated fat and cholesterol intake, can potentially reduce high blood pressure by up to 11 mm Hg.

Engage in regular physical activity
Consistent physical exercise can significantly lower elevated blood pressure. Sustaining an exercise routine is vital to prevent blood pressure from surging once more. Strive for a minimum of 30 minutes of moderate physical activity daily as a general guideline. Regular exercise not only helps prevent elevated blood pressure from escalating into hypertension but can also bring down blood pressure to safer levels for individuals already diagnosed with hypertension.
