Scientists discover how a decades-old drug reduces the size of a heart attack
Scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have discovered a new mechanism of action of metoprolol, a drug that can reduce the damage produced during a heart attack if administered early. The team led by Dr. Borja Ibáñez, Clinical Research Director at the CNIC and cardiologist at the Fundación Jiménez Díaz University Hospital Health Research Institute (IIS-FJD), has identified the mechanism that explains why this drug is so beneficial: rapid administration of metoprolol during a heart attack directly inhibits the inflammatory action of neutrophils, a type of blood cell.
A Twitter poll found that most cardiologists have reported a 40% to 60% reduction in hospital admissions for heart attacks as the coronavirus pandemic continues to spread.

HOW to live longer: Prevent an early death by eating a healthy, balanced diet, and by doing regular exercise. But you could also increase your life expectancy and lower your risk of heart attack symptoms and signs and early death by adding this cheap snack to your daily routine.
In most cell therapies, the transplanted cells do not survive for long, or in large numbers. They produce beneficial effects, such as reduced inflammation or enhanced regeneration, via signaling that changes the behavior of native cell populations. Considerable effort is going into finding ways to make cells used in therapy survive for a longer period of time following transplantation. The approach taken here is to engineer a fraction of the transplanted cells to produce a growth factor that improves the survival of the others. The results are demonstrated in an animal model, showing a greater regeneration of heart muscle....
Since the onset of the novel coronavirus COVID-19, hospital emergency departments have seen a precipitous drop in the number of heart attack patients presenting for treatment. The big question is why? Are there really less heart attacks occurring, or are patients staying home, afraid to come to the hospital for fear of contracting the virus? There's good reason to believe that the latter may be the case, and the implications are extremely troubling.
Composed primarily of collagen and strengthened with cross-linked fibers, scar tissue that forms after a heart attack doesn ’t contract as well as healthy muscle tissue. It can therefore compromise the organ’s ability to pump blood, which may lead to heart failure, arrhythmias, and sudden cardiac death. Scientists who developed a therapy that targets such scar formation, or fibrosis, recently brought their strategy a step closer to the clinic. After demonstrating its effectiveness in rodents, their latest work—a randomized, double-blinded pig study—validates the approach in a large-animal model.
Conclusions: Our study results were not consistent with the hypothesis that PPI use increases MI risk among people without known heart disease.
Hypertension affects approximately 85 million Americans, or almost 1 in 3 adults. Black men have disproportionately higher rates of hypertension and are more likely to experience complications of hypertension, including stroke, myocardial infarction, and death. In addition, hypertensive black men are less likely to achieve optimal blood pressure (BP) than women and persons of other races. In light of this, we performed a literature search for articles published from January 1, 1966, to December 31, 2018, using terms including hypertension, blood pressure, black male, and African American male.
Cardiovascular diseases (CVDs) are a significant health burden with an ever-increasing prevalence. They remain the leading causes of morbidity and mortality worldwide. The use of medicinal herbs continues to be an alternative treatment approach for several diseases including CVDs. Currently, there is an unprecedented drive for the use of herbal preparations in modern medicinal systems. This drive is powered by several aspects, prime among which are their cost-effective therapeutic promise compared to standard modern therapies and the general belief that they are safe. Nonetheless, the claimed safety of herbal preparations ...
