Active cardiac conditions

Condition	Examples
Unstable coronary syndromes	Unstable or severe angina—CCS class III or IV^*
Unstable coronary syndromes	Recent MI^†

Decompensated heart failure	NYHA functional class IV Worsening heart failure New onset heart failure

Significant arrhythmias	High-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 disease	Severe aortic stenosis: mean pressure gradient >40 mm Hg, aortic valve area <1.0 cm² or symptomatic
Severe heart valve disease	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.
