Table 3. Numbers of cumulative major and minor cardiovascular events in patients with intermittent claudication during the prospective follow-up, shown for the first 5 years and the entire follow-up time.

	First 5 years of follow-up	Entire follow-up time
Major cardiovascular events	N of events = 25	N of events = 38
Fatal cardiovascular events (ICD10 Codes I00-I99)	8^b	13^b
Non-fatal myocardial infarction (MI)^a	14	21
Ischemic cerebral infarction^a	4	6
Minor cardiovascular events	N of events = 31	N of events = 38
Percutaneous transluminal coronary angioplasty (PTCA)^a	11	13
Aortocoronary bypass	9	10
Angiographically proven coronary stenosis (CAG) ≥ 50%^a	4	5
Transient ischemic attack (TIA)^a	6	9
Carotid endarterectomy (CEA)^a	1	1

^aTwo patients had a TIA (=first event) and an ischemic stroke (=second event), 1 patient had a CAG (=first event) and an ischemic stroke (=second event); 1 patient had a PTCA (=first event) and an ischemic stroke (=second event); 1 patient had a CEA (=first event) and a MI (=second event) and 1 patient had a TIA (=first event) and a MI (=second event): n = 6. In these patients, the first event was included in the minor and the second event in the major composite cardiovascular endpoint, respectively. ^bTwo patients (one within the first five years) suffered a fatal cardiovascular event and had a non-fatal event before and thus the non-fatal event was considered in the analysis of the major cardiovascular endpoint.
