High blood pressure impacts about 45% of adults in the United States. Back in the 1970s, only around half of those with the condition knew they had it. Presently, 54% of people recognize that they have high blood pressure, 40% are receiving treatment, and 21% have their condition under control. Consequently, researchers are warning health care providers that this “silent killer” continues to pose a significant threat. It is recommended that healthy adults maintain a systolic blood pressure of 130 mmHg or lower and a diastolic pressure of 80 mmHg or lower.
Cardiovascular disease is the top preventable cause of early death and disability both in the U.S. and worldwide. It includes conditions such as heart attacks and strokes, resulting in over 900,000 deaths annually in the U.S. and around 10 million deaths globally.
Uncontrolled high blood pressure is a significant risk factor for both heart attacks and strokes. To prevent and manage cardiovascular disease, individuals are encouraged to adopt healthier lifestyles, including improved diet and increased physical activity, alongside proven drug therapies.
In a commentary featured in The American Journal of Medicine, researchers from Florida Atlantic University’s Schmidt College of Medicine warn that uncontrolled hypertension is a prevalent and serious health issue affecting patients today.
Dr. Stacy Rubin, the senior author and assistant professor of medicine at FAU Schmidt College of Medicine, stated, “Healthcare providers must recognize that uncontrolled hypertension is one of the most common, sobering, and growing conditions among their patients. It is crucial that they focus on managing blood pressure since sudden cardiac death accounts for half of all cardiovascular disease-related fatalities, and roughly 25% of these cases are the first warning sign. Additionally, for 76% of stroke patients, the stroke is the initial symptom they experience.”
The authors emphasize that managing hypertension is both effective and theoretically straightforward. Before the Hypertension Detection and Follow-Up Program, a pivotal study from the 1970s in the U.S., only about half of patients knew they had high blood pressure. Among those, only 50% received treatment, and only half of that group received effective treatment—resulting in only 1 out of every 8 patients effectively being treated.
Today, statistics show that 54% of patients are aware of their high blood pressure, 40% are being treated, and 21% have their condition controlled. Many countries around the globe have established guidelines emphasizing the importance of stringent blood pressure management. According to the latest recommendations from the American Heart Association and the American College of Cardiology, healthy adults should maintain a systolic blood pressure below 130 mmHg and a diastolic pressure under 80 mmHg.
Dr. Panagiota “Yiota” Kitsantas, co-author and chair of the Department of Population Health and Social Medicine at FAU Schmidt College of Medicine, noted, “With these new definitions, hypertension now affects approximately 45% of the adult population in the U.S. Another clinical concern is metabolic syndrome, characterized by central obesity, elevated triglycerides, low levels of HDL cholesterol, high fasting blood sugar, and high blood pressure.”
The authors warn that metabolic syndrome is a significant risk factor for heart attacks and strokes, particularly in the U.S., which has the highest obesity rates in the world.
Dr. Charles H. Hennekens, co-author and the first Sir Richard Doll Professor of Medicine, emphasizes that “For those with metabolic syndrome, we recommend angiotensin-converting enzyme (ACE) inhibitors or their newer, more potent variants, the receptor blockers, as the initial choice of medication. These medications are beneficial for reducing risks associated with heart attacks, strokes, and kidney disease, all of which are significant complications of untreated hypertension.”
Making healthy lifestyle changes—such as losing weight, increasing physical activity, and reducing salt intake—has proven effective in managing blood pressure. For individuals whose blood pressure exceeds 130/80, combining these lifestyle modifications with medications can successfully lower blood pressure. Medications are generally recommended for individuals whose blood pressure remains above 140/90 despite lifestyle changes.
The authors advise that both healthcare providers and patients should understand that blood pressure can vary from day to day and throughout the day. Consequently, managing treatment can be complex, necessitating that providers create tailored approaches for each patient. Additionally, patients should actively monitor their blood pressure levels. For this reason, the American Heart Association and the American College of Cardiology endorse the use of the Omron blood monitor for home blood pressure measurements.
Dr. Hennekens further suggests, “Healthcare providers should encourage their patients to measure their blood pressure each morning and evening and to adjust their medication doses based on the average of three readings taken five minutes apart.” While uncontrolled hypertension remains prevalent both in the U.S. and globally, diligent attention to these aspects by healthcare providers can significantly reduce the impact of this “silent killer.”
