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.

TCT 2017: 6-month DAPT regimen non-inferior to recommended 12 months in STEMI patients

Six months of dual antiplatelet therapy (DAPT) was found to be non-inferior in ST-elevation myocardial infarction (STEMI) patients to the internationally recommended 12-month regimen in a pioneering trial presented at the 29th annual Transcatheter Cardiovascular Therapeutics (TCT) conference in Denver.

TCT 2017: ‘Landmark study’ could change practice for acute MI coupled with cardiogenic shock

DENVER — Patients with acute MI complicated by cardiogenic shock demonstrated significantly higher 30-day survival rates with culprit lesion PCI versus multivessel PCI, according to a new study that challenges current guidelines.

Women more likely to die within a year of heart attack than men

New research published in PLOS One this October reports not only do more women statistically die of acute myocardial infarction (AMI) than men, but they see dramatically increased mortality in the first year after their heart attack.

Lipoprotein(a) not linked to increased CVD risk in ACS patients after all

Although the atherogenic lipoprotein(a) [Lp(a)] has been associated with incident cardiovascular disease, its concentration doesn’t predict the risk of ischemic cardiovascular events following acute coronary syndrome (ACS) in patients receiving other therapies, a study published in JAMA Cardiology reports.

Rebound hyperthermia dangerous for the neurological health of comatose heart patients

Postcardiac arrest patients who experience rebound hyperthermia (RH) after targeted temperature management (TTM) therapy could be at a greater risk for developing neurological disabilities, a study published in Therapeutic Hypothermia and Temperature Management states.

Non-MI patients with elevated cardiac troponin remain at increased risk

Any detectable level of high-sensitivity cardiac troponin T (hs-cTnT) measured in an emergency department (ED) was associated with worse long-term survival—even when not accompanied by acute conditions known to impact troponin levels—according to a Swedish study published in the Journal of the American College of Cardiology.

Half of smokers continue the habit after a cardiovascular event

Half of habitual smokers who experience myocardial infarction (MI), stroke or other adverse cardiovascular events continue to smoke cigarettes after hospitalization, a study from South Korea has found.

Diabetes may affect heart attack symptoms, delay diagnosis

Diabetics may feel less pain during a heart attack than other people, leading to inaccurate self-diagnoses and delays in seeking treatment, according to a small qualitative study published online in BMJ Open.
