What is the long-term incidence of stroke or death in patients with TIAs, RINDs, and infarctions with minimum residuum?
Patients with TIAs, RINDs, and minor infarctions have a 14% cumulative incidence of stroke or death at 5 years, with disabling stroke being less frequent after minor infarctions than after TIAs or RINDs.
A group of patients with transient ischemic attacks (65 cases), reversible ischemic neurologic deficits (37 cases) and infarctions with minimum residuum (41 cases) was included in a prospective follow-up for a mean period of 5.2 years. Most of the patients were treated with acetylsalicylic acid or other antiplatelet agents, or with anticoagulants. Principal complications during follow-up were: cerebral infarction, 15 cases (10.4%); cerebral hematoma, 2 (1.3%); transient ischemic attacks, 17, (11.8%); reversible ischemic neurologic deficits, 9 (6.2%); myocardial infarction, 4 (2.7%); and death, 11 (7.6%). The cumulative incidence for stroke or death was 6.2% for the first year and 14% for the fifth year. There were no significant risk factors for the occurrence of stroke or vascular death on time-related multivariate analysis (Cox). Disabling stroke was less frequent after infarctions with minimum residuum than after transient ischemic attacks or reversible ischemic neurologic deficits.
