COVID-19 Survivors Face Doubled Risk of Heart Attacks and Strokes for Years to Come!

A groundbreaking study has unveiled a chilling reality for COVID-19 survivors: individuals infected with the virus during the early days of the pandemic may face a staggering double the risk of heart attacks, strokes, or premature death for up to three years after their illness, even if they never experienced severe symptoms. This alarming revelation underscores the long-term health implications of the virus and the urgent need for ongoing medical awareness.

The research, published in the American Heart Association journal "Arteriosclerosis, Thrombosis, and Vascular Biology," reveals that hospitalization for COVID-19 equated to a significant increase in coronary artery disease risk. Remarkably, this heightened risk applies to individuals without any prior cardiovascular issues, placing them at greater risk than those with a history of heart disease who did not contract COVID-19. The study's authors have pointed out a notably increased risk among those with non-O blood types, marking a significant interaction between genetics and the virus that may lead to heart-related events.

Dr. Hooman Allayee, a co-senior author of the study and professor at USC's Keck School of Medicine, emphasized that the dangers extend well beyond the initial infection phase. "Our findings indicate that even those with mild cases are not exempt from long-term cardiovascular complications," he stated. The lingering impacts of COVID-19 on the vascular system are becoming increasingly evident, especially as some individuals continue to suffer from long-term symptoms or "long COVID."

Previous studies had already shown that up to a quarter of COVID-19 patients hospitalized could suffer cardiovascular consequences, including heart attacks, heart failure, and strokes. Additionally, genetic factors play a significant role, as people with type O blood appear to have a lower risk of infection and subsequent cardiovascular problems compared to those with A, B, or AB blood types.

The current study analyzed health data from over 10,000 participants from the UK Biobank, focusing on individuals who tested positive or were hospitalized for COVID-19 from February to December 2020. The researchers tracked heart attacks, strokes, and deaths for approximately three years post-infection. The results were startling: patients who had COVID-19 were twice as likely to suffer major cardiovascular events, while those hospitalized faced nearly four times the increased risk compared to COVID-negative individuals.

Despite the study being observational rather than randomized, experts are taking the findings seriously. Dr. Sandeep Das, a cardiologist at UT Southwestern Medical Center, noted, "While we can't definitively state causation, the association highlighted by this research warrants serious consideration, particularly regarding the role blood type may play in cardiovascular vulnerability post-COVID-19."

The implications for public health are profound. As the world adjusts to a new normal, there is a growing urgency to devise treatment strategies not only for those currently suffering from acute COVID-19 but also for those who have survived but are at increased risk of serious health issues. The study raises important questions about whether individuals who were hospitalized for COVID-19 should be treated with preventive measures akin to those for patients with a history of heart disease, like antiplatelet medications.

Dr. Allayee raised a thought-provoking question: "Should we begin treating these patients, especially those without cardiovascular history, with medications like aspirin to mitigate their elevated risks?"
