Its devastating effects have resulted in the mobilization of major resources, both at the national, state, and individual levels. This mobilization has resulted in vaccination, personal preventive measures, and new therapies to combat this illness. As a result, the rates of new infections, hospitalizations, and deaths have greatly diminished, minimizing the associated morbidity and mortality. Purpose: What has not been appreciated is that a more serious epidemic has continued unabated in the United States and the Western world. This article emphasizes the importance of a national effort to eradicate cardiovascular disease. Methods: Cardiovascular disease has caused more deaths than COVID-19 in almost all months since the COVID-19 epidemic was first recognized in December 2020. In fact, cardiovascular disease has caused more deaths than either all cancers combined or infections for the last two decades. The tragedy of this truth is that effective therapy is currently available for preventing and reversing cardiovascular disease at a very low cost. What is required is a concerted effort and commitment by all legislative and medical organizations to allocate the resources to abolish asymptomatic cardiovascular disease. Results: Recognition and mobilization of resources to combat this epidemic are much overdue with the resultant savings of lives and billions of dollars. It is past time for the medical establishment to support the national identification of asymptomatic cardiovascular disease and initiate treatment before patients become symptomatic with this deadly disease. Conclusion: The national experience with COVID-19 has demonstrated what can be accomplished when a national concerted effort is made to address a devastating medical epidemic. This commitment is not only feasible for cardiovascular disease, but is also necessary for the benefit of all people in the world.展开更多

A popular NFL player, Damar Hamlin, safety for the Buffalo Bills, suffered a cardiac arrest on January 2, 2023. Due to prompt intervention and CPR, Hamlin survived the arrest and is playing again. This research sought to understand how people respond to this event on the internet. It also seeks to understand how this response can be used to raise CPR awareness. Design and Methods: Using Google Trends and Twitter data, we searched, downloaded, and retrospectively analyzed search interests relative to Hamlin’s cardiac arrest for a one-year duration. We searched for related keywords in the United States from March 2022 to March 2023, including “Damar Hamlin”, “sudden cardiac death”, “heart attack”, and “CPR”. Results: There was a significant rise in post-event Google searches that combined the terms “Damar Hamlin” and “SCD” (M = -28898.88, SE = 1537.66;t = 1.62, p Conclusion: Based on the analytics of these platforms, it can be concluded that there were active discussions and an awareness of life-saving skills such as CPR along with Hamlin’s cardiac event by his fans, as demonstrated by the data gathered from these platforms. This can provide us with valuable insight into human behavior and help us leverage this knowledge to promote health.展开更多
