Cocaine, amphetamines and cannabis could raise adolescents’ risk for acute myocardial infarction (AMI), in some cases increasing a teen’s odds for MI by up to seven times, according to research out of Shanghai Jiao Tong University School of Medicine in China.

Critical shortages of imaging equipment and qualified radiologists left an estimated 56,000 angina patients without access to potentially lifesaving computed tomography (CT) scans last year, the Royal College of Radiologists and British Society of Cardiovascular Imaging announced Nov. 8.

Poor health literacy could mean an increased risk of death for patients hospitalized with acute decompensated heart failure (ADHF), according to a study published in Mayo Clinic Proceedings Nov. 7.

A new study in JAMA Cardiology showed patients’ risk perceptions and willingness to accept therapy are influenced by the type of estimate they’re presented with and how that information is organized.

The FDA has approved canagliflozin (Invokana) to reduce the risk of major adverse cardiovascular events (MACE) including stroke, heart attack and cardiac death in patients with type 2 diabetes and established cardiovascular disease. It is the first oral diabetes medication to gain this indication, according to drug manufacturer Janssen Pharmaceutical Companies.

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.
