Acute Coronary Syndromes

Acute coronary syndrome (ACS) is most commonly caused by a heart attack (myocardial infarction) where blood flow to the heart is suddenly blocked. This is usually caused by a blood clot from a ruptured coronary artery atherosclerotic plaque. Other causes include spontaneous coronary artery dissection (SCAD), which most commonly occurs in women. ACS is usually treated in a cath lab with angioplasty and the placement of a stent to prop the vessel open.

Cian McCarthy, MD, cardiovascular fellow, Massachusetts General Hospital, and a member of the National Cardiovascular Data Registry (NCDR) Chest Pain-MI registry steering committee, explains a study of the NCDR data showing only 33% of hospitals are using high-sensitivity troponin. However, he expects that to rise because of high sensitivity troponin (hs-cTn) being included in recent guidelines as a front-line test.

Former U.S. Surgeon General Jerome Adams (2017-2021) spoke at the opening session of the American Heart Association (AHA) 2022 Scientific Sessions last week and said cardiologists need to help end the COVID pandemic and tackle the even bigger epidemic of hypertension. He highlighted hypertension and called it a clear public health emergency, causing more than 670,000 U.S. deaths per year. #AHA22 #hypertension

Former surgeon general says cardiologists need to address hypertension and remaining COVID cases

Drinking coffee may increase the risk of coronary heart disease among men

Among women, on the other hand, drinking coffee may actual reduce the risk of CHD. The full meta-analysis, based on data from 32 different studies, was published in the American Journal of Cardiology.

Heart disease-related deaths increased due to COVID-19, undoing a decade of progress

American Heart Association President Michelle A. Albert, MD, urged physicians to seek out patients who may have not received medical care since the start of the pandemic. These patients could face an increased risk of cardiac complications.

A team of cardiologists and cardiac surgeons in Hong Kong has performed the first successful undermining iatrogenic coronary obstruction with radiofrequency needle procedure—or UNICORN for short—on a high-risk valve-in-valve transcatheter aortic valve replacement (TAVR) patient. The group wrote about their experience in Circulation: Cardiovascular Interventions, a journal launched and distributed by the American Heart Association.

Cardiologists make history, perform first UNICORN procedure during valve-in-valve TAVR

BASILICA was considered for the 67-year-old female patient, but UNICORN was seen as an overall better option. The full case study was published in Circulation: Cardiovascular Interventions.

American College of Cardiology shares expert analysis on treating ASCVD patients with multiple chronic conditions

The new guidance document was designed to help cardiologists and other clinicians deliver the best care possible when treating ASCVD patients who present with additional conditions that need to be considered. 

Leading cardiologists sound the alarm, say polypills could save millions of lives if made widely available

“This systemic failure is a global tragedy, as many premature deaths from CVD could be avoided,” one cardiologist said.
