Active cardiac conditions

Unstable coronary syndromesUnstable or severe angina—CCS class III or IV*
Recent MI
Decompensated heart failure
  • NYHA functional class IV

  • Worsening heart failure

  • New onset heart failure

Significant arrhythmiasHigh-grade atrioventricular block
Mobitz II atrioventricular block
Third degree atrioventricular heart block
Symptomatic ventricular arrhythmias
Supraventricular arrhythmias including atrial fibrillation with uncontrolled ventricular rate: HR >100 beats/min at rest
Symptomatic bradycardia
Newly recognised ventricular tachycardia
Severe heart valve diseaseSevere aortic stenosis: mean pressure gradient >40 mm Hg, aortic valve area <1.0 cm2 or symptomatic
Symptomatic mitral stenosis: progressive dyspnoea on exertion, exertional presyncope or heart failure
  • * May include ‘stable’ angina in patients who are unusually sedentary.

  • The American College of Cardiology National Database Library defines recent MI as >7 days but ≤1 month within 30 days.

  • CCS, Canadian Cardiovascular Society grading for angina pectoris; HR, heart rate; MI, myocardial infarction; NYHA, New York Heart Association.
