The first study of COVID-19 vaccine effectiveness in a large population of adult heart-failure patients suggests that vaccinated participants are 82% more likely to live longer than their unvaccinated peers, according to an analysis presented over the weekend at the Heart Failure 2024 scientific congress of the European Society of Cardiology (ESC) in Lisbon, Portugal.

Post-COVID ‘heart failure pandemic’ possible: Japan researchers
After contracting COVID-19, patients may have higher risk of heart failure from persistent viral infection in their hearts, even without developing notable heart disease, according to study results announced by Japanese researchers on Dec. 23.
The team including researchers from Riken, Japan’s largest scientific institute, pointed out the possibility of a “heart failure pandemic” in the near future, and is stressing the need for countermeasures.

Why some doctors see COVID as a new risk factor for cardiovascular disease
The severity of the infection doesn’t seem to make a difference. These complications can occur even in people who have very mild symptoms. The big surprise is how much this can affect younger people. Studies are showing that even young, active people can experience heightened risk of these complications.
High blood pressure, high cholesterol, diabetes, obesity: These are some of the well-known risk factors that can put people at heightened risk for heart attack and stroke.
Now some health experts say COVID-19 should be added to that list.

コロナ感染、心不全のリスク高まる可能性 理研など研究
On December 23, a research team from Riken and other institutes announced the results of a study showing that after infection with the novel coronavirus, the heart may be persistently infected with the virus and the risk of heart failure may increase, even if the patient does not develop noticeable heart disease. The team points to the possibility of a sharp increase in the number of heart failure patients in the near future and calls for countermeasures to be taken.
Infection with the novel coronavirus occurs when a protruding “spike protein” on the surface of the virus binds to the ACE2 receptor on the surface of human cells. According to the team, the heart is more likely to express ACE2 compared to other organs. It has also been reported that some people infected with the novel coronavirus have reduced cardiac function, but the detailed mechanism is not known.

Even Mild COVID Can Increase the Risk of Heart Problems
Overall, the risk of any heart complication over the course of one year was 63 percent higher in people who had gotten COVID compared with those in the contemporary control group. At the end of a year, there were 45 additional cardiovascular events—such as stroke or heart failure—per 1,000 people among those who tested positive for COVID.
