Acute Coronary Syndrome

Though it’s been linked tenuously in the past to psychological stressors and genetics, the majority of cases of spontaneous coronary artery dissection (SCAD) can’t be traced back to a concomitant arteriopathy, inflammatory disorder or evident risk factor, according to research published in the American Journal of Cardiology Oct. 29.

Patients with normal arteries upon coronary CT angiography (CTA) experienced either death or myocardial infarction at a rate of 0.04 percent per year, according to a study with 10 years of follow-up published in JACC: Cardiovascular Imaging.

The majority of ST-segment elevation myocardial infarction (STEMI) patients in the Midwest live within an hour of their nearest percutaneous coronary intervention (PCI)-capable hospital and are able to undergo primary PCI within two hours of an MI, researchers reported in the American Journal of Cardiology.

Colder temperatures, stronger winds and fewer hours of sunlight could all raise a person’s risk of myocardial infarction, researchers reported in JAMA Cardiology.

Patients evaluated for chest pain in busier emergency departments experience lower rates of death or hospitalization for acute coronary syndrome (ACS) at both 30 days and one year, according to a study published Oct. 23 in Circulation: Cardiovascular Quality and Outcomes.

Canada legalized recreational cannabis countrywide Oct. 17, triggering a national response that’s resulted in near-depletion of the country’s legal marijuana supply. But, as Canadians begin to embrace the new policy, local physician Taylor Lougheed, MD, MSc, suggests heart patients might want to consider their cardiovascular health before lighting up.

Certain antiphospholipid antibodies were detected more often after heart attacks than for age-matched controls, suggesting the markers could be used to identify patients at high risk of myocardial infarction, according to a study published Oct. 22 in the Annals of Internal Medicine.

Coronary artery calcium (CAC) is predictive of all-cause and cardiovascular mortality across all racial and ethnic groups, according to a study published in the Journal of the American Heart Association—but the risk of those outcomes is significantly higher across all CAC scores for black and Hispanic patients than for whites and Asians.

The FDA rejected Norvartis’ bid to expand the indications for canakinumab to include cardiovascular risk reduction among heart attack survivors, Reuters reported Oct. 18.

Patients with heart disease should aim to be physically active seven minutes for every 20 they’re sedentary to prolong life and prevent further cardiovascular damage, according to research presented at the 2018 Canadian Cardiovascular Congress in Toronto.

A novel risk score incorporating patient demographics and clinical characteristics known ahead of hospital discharge can accurately identify CVD patients at low and high risk for 90-day readmission after an initial acute MI (AMI), according to research published in the October edition of Circulation: Cardiovascular Quality and Outcomes.
