Black women, High Blood Pressure, Heart Disease: What We Don’t Know is Killing Us.

Black Women, High Blood Pressure, Heart Disease:

What We Don’t Know Is Killing Us.

The larger population of black women are unaware of the risks that cardiovascular disease (CVD) poses. According to the American Heart Association (AHA), only 36% of black women are aware that it is our greatest health risk and our number one killer. One of the known leading risk factors to CVD is hypertension or high blood pressure. Of the 36% who know, few are taking the necessary steps to reduce these risks. Thanks to the corona virus pandemic, normal day-to-day activities have been dramatically altered or reduced, stress and anxiety levels as well as sedentary behaviors have increased; risk factors that can trigger a cardiac event. In addition, annual check-ups where doctors will check for signs of risk factors, have also been neglected.


We all hear that having high blood pressure is bad. What isn’t as well-known is how having high blood pressure impacts overall cardiac health. The American Heart Association states that “58% of black women in the US have high blood pressure and death from high blood pressure-related causes are nearly double that of white women and more than twice the rate for Hispanic women.” There are a number of reasons that exist for having high blood pressure, ranging from salt sensitivity to family history. However, behaviors which contribute to high blood pressure such as unhealthy eating habits, remaining sedentary and being overweight or obese, can be self corrected. Participating in physical activity, making changes to dietary habits and taking steps to reduce stress are a few examples. Several studies have expressed that estimated cardiovascular benefits from interventions and modified behaviors can completely eliminate hypertension or uncontrolled hypertension from the population. And yet studies also show that black women are less likely to participate or make these changes. Why is that? Awareness and knowing your numbers may be key to altering perceptions of the impact of CVD.


What exactly is blood pressure and the importance of knowing your numbers

The phrase “Know your numbers” has become part of the lexicon when discussing CVD and heart health. I conducted a random survey with a few of my female friends and colleagues and asked 2 questions, “What is high blood pressure and why is having high blood pressure bad?” Everyone knew a little something but most did not know the critical reasons why high blood pressure is a catalyst to CVD. 

Blood pressure is an important diagnostic tool used to detect possible risk factors. Blood pressure measures the force of blood passing through arterial walls, determining the diameter and elasticity, and with which the heart needs to push it through the circulatory system (aorta, ventricles, arteries, veins and capillaries) to complete a cycle. For most adults, normal blood pressure is defined as 120/80 (systolic/diastolic) with at risk for high blood pressure and high blood pressure 120-139/80-89 and 140/90 respectively. This emphasizes that knowing your numbers becomes important in managing CVD risk. Overtime, high blood pressure can cause damage to arterial walls by weakening them and/or causing aneurysms which can lead to strokes. Think of this as a rusting pipe that begins to wear down overtime and eventually bursts causing a massive flood. Also, the narrowing of the walls caused by a buildup of plaque deposits, reduces elasticity and restricts blood flow. This stresses the heart, requiring an increased workload to move the blood, eventually wearing it down and possibly resulting in a heart attack. Knowing your numbers can determine whether you are at risk for heart disease and dictate how it should be managed. Understanding blood pressure in addition to knowing the numbers that define it, helps guide decision making and behavioral changes necessary to manage it as well as preserve and extend life.


Lack of Awareness in Communities of Black Women

As cardiovascular disease is the leading killer of black women, factors like an inherent distrust of the medical community based on historical cases like the Tuskegee experiment and/or receiving unequal and often biased treatment from medical professionals when seeking care. When our blood pressure is taken with high results, recommendations for management often come in short form; that the patient should exercise more, that they should eat better and depending how high the pressure is measured, placed on medication. What does exercise more mean? What does eat better mean? A next step would be to not only recommend these changes but to educate these patients on what these changes mean. However, so much can be done in one medical visit and why it is so important to find ways to spread awareness because the numbers suggest that current efforts have not been as effective in communities of black women. The need for advocacy dedicated to these populations by persons who look like themselves (#RepresentationMatters) can provide a lifeline when it comes to educating and bringing awareness to the black community in an effort to mitigate future risks. 


What’s next?

High blood pressure and its implications are preventable or manageable. Scheduling a medical check up to learn your number and behavioral and lifestyle changes are good first steps. Education which promotes ways to make small changes to diet, like increasing servings of fruits and vegetables, eating foods low in sodium and saturated fats, as well as adding regular physical activity can effectively reduce high blood pressure and CVD which leads to death in so many black women. Learning how to modify behaviors to other known risk factors that contribute to high blood pressure like smoking, alcohol consumption, stress levels and inadequate sleep should also be performed. Also purchasing a personal blood pressure monitor for home use between doctor visits is a way to be aware of and be active in developing and maintaining healthy heart habits. The hope is in building more awareness of high blood pressure and its effect on heart disease risk in black women and how the prevention and mitigation of these risk factors will ultimately decrease the mortality rates through cardiovascular disease.
