Classification Identifies Four Stages of Heart Attack

Relying on more than 50 years of data on acute MI with reperfusion therapy, the society has identified the following four stages of progressively worsening myocardial tissue injury:

  1. Aborted MI (no or minimal myocardial necrosis).

  2. MI with significant cardiomyocyte necrosis but without microvascular injury.

  3. Cardiomyocyte necrosis and microvascular dysfunction leading to microvascular obstruction (that is, "no-reflow").

          Cardiomyocyte and microvascular necrosis leading to reperfusion hemorrhage.

Scientific news

  • Prenatal Exercise Cuts Common Pregnancy Complications Moderate-intensity physical activity during pregnancy is known to be safe for the mother and foetus, but does it reduce the risk for medical complications? A new up-to-date review summarises the data, including seven meta-analyses, which establishes that prenatal exercise prevents hypertension disorders in pregnancy (HDP), including gestational diabetes mellitus (GDM). These are the most common medical complications of pregnancy, affecting up to 15% of pregnant women.
  • Heart Failure, Not Stroke, Most Common Complication of A-Fib The lifetime risk of atrial fibrillation (AF) increased from 2000 to 2022 from one in four to one in three, a Danish population-based study of temporal trends found.
  • Incremental value of machine learning for risk prediction in tetralogy of Fallot Machine learning (ML) can facilitate prediction of major adverse cardiovascular events (MACEs) in repaired tetralogy of Fallot (rTOF). We sought to determine the incremental value of ML above expert clinical judgement for risk prediction in rTOF.
  • Can Treating Depression Mitigate CVD Risk? Depression is linked to a significantly increased risk for cardiovascular disease (CVD), particularly in women, new data from a large retrospective cohort study show. Researchers suggest that screening and treating patients for depression may lead to a decreased incidence of CVD.
  • Gout Increases the Risk for a Wide Range of Cardiovascular Diseases People with gout are 58% more likely to develop cardiovascular disease (CVD), according to a new analysis. This increased risk was observed across 12 different cardiovascular conditions, including heart failure, arrhythmias, and valve diseases.
