Beta blockers not needed after heart attack if other medications taken


Beta blockers are not needed after a heart attack if heart-attack survivors are taking ACE inhibitors and statins, new research suggests. The study is the first to challenge the current clinical guideline that heart-attack survivors should take all three drugs — beta blockers, ACE inhibitors and statins — for the rest of their lives.

Re-interventions are common in long-term survivors of childhood heart operation


Among patients who undergo childhood heart surgery for the severe birth defect single-ventricle disease, two-thirds of survivors require a surgical or catheter-based procedure within 20 years. Pediatric cardiology researchers note that doctors should counsel families about the likelihood of re-interventions.

Researchers closer to uncovering a new feature in heart failure


Each cell in the average human body contains 23 pairs of chromosomes, with four telomeres on each pair. Telomeres cover the end of the chromosome, protecting it from deterioration or fusion with adjacent chromosomes. While there is a length range for classifying a healthy telomere, researchers found, for the first time ever, that people with heart failure have shorter telomeres within the cells that make up the heart muscle (known as cardiomyocytes).

Uncovering the mechanism behind heart failure, mortality in sepsis


Of the nearly 1 million people in the US who are affected by sepsis annually, almost one-fifth die. Cardiovascular complications account for approximately 80 percent of those deaths. Now, researchers describe the mechanism underlying the loss of energy from heart dysfunction in sepsis, opening the way for the development of a new therapy that could save thousands of lives annually.

Emoji fans take heart: Scientists pinpoint 27 states of emotion


The Emoji Movie, in which the protagonist can’t help but express a wide variety of emotions instead of the one assigned to him, may have gotten something right. A new study challenges a long-held assumption in psychology that most human emotions fall within the universal categories of happiness, sadness, anger, surprise, fear and disgust.
