Exclusion criteria
Exclusion criteria: A potential subject who meets any of the following criteria will be excluded from participation in this study: - Presence of an absolute contra-indication for the performance of exercise (see also SOP Inspanningstest Department of Physiology): - Acute myocardial infarction (3-5 days) - Unstable angina - Uncontrolled arrhythmias causing symptoms or hemodynamic compromise - Active endocarditis - Acute myocarditis or pericarditis - Symptomatic severe aortic stenosis - Uncontrolled heart failure - Acute pulmonary embolus or pulmonary infarction - Thrombosis of lower extremities - Suspected dissecting aneurysm - Uncontrolled asthma - Pulmonary oedema - Respiratory failure - Acute noncardiopulmonary disorder that may affect exercise performance or be aggravated by exercise (i.e. infection, renal failure, thyrotoxicosis) - Mental impairment leading to inability to cooperate - Use of medication that alters the effect of cardioprotection: • ß-blockers • Calcium Channel blockers • Nitrates • Opioids • Anti-platelet agents (e.g. paracetamol) • Statins and anti-hyperlipidaemic drugs • Anti-diabetic treatment
