Recent studies, including one led by researchers at Beth Israel Deaconess Medical Center (BIDMC), suggest that cytomegalovirus (CMV)—a prevalent viral infection—may be a contributing factor to high blood pressure, a major risk factor for heart disease, stroke, and kidney disease. Infection-induced stress on the heart, particularly due to COVID-19, can result in elevated heart rate and fluctuating blood pressure, which may exacerbate cardiac issues, especially in individuals with pre-existing conditions. Additionally, research indicates a potential link between COVID-19 infection and new-onset high blood pressure, particularly in adults with pre-existing heart conditions or those who are older, Black, or male. The SARS-CoV-2 virus, responsible for COVID-19, can infect heart muscle and blood vessel cells, leading to direct damage or indirect harm through coagulation and blocked arteries. Despite vaccination efforts, high blood pressure remains a significant risk factor for severe COVID-19 outcomes. Furthermore, hypertension exacerbates stress on various organs, and medications are often necessary to manage its adverse effects. Lifestyle changes, alongside medications, can reduce hypertension, thus decreasing the risk of strokes and heart attacks.
