Stroke is a serious but infrequent complication of PCI, increasing the risk of stroke by 17 times. Patients suffering this complication have higher morbidity and mortality rates.
 
Materials and methods
Demographic, procedural, and stroke features of a population of 24 patients with stroke occurring within 30 days after PCI for myocardial infarctions (MI) is described. Data was retrospectively collected from the Centro Cardiovascular Universitario of the Hospital de Clí­nicas in Montevideo, Uruguay between 2008-2017.
 
Results
54.2% of patients were man. Cardiac risk factors were present in the studied population, such as cigarette smoking (70.8%), hypertension (79.2%), diabetes (16.7%), and dyslipidemia (45,8%). 37.5% percent had prior stroke. 66.7% presented NSTEMI. 70.8% had ischemic stroke, the rest where transient ischemic attacks. 62% occurred in the first 48 hours after PCI, having this group a higher percentage of ATC and longer procedures. 79.2% were anterior brain circulation strokes. In three patients Tissue Plasminogen Activator was used for stroke treatment. NIHSS median was 4 (p25: 2 p75: 8) in NSTEMI and 8 (p25: 3 p75: 20) in STEMI (p=0.20). 79% of patients had complications during the hospitalization, and 5 died.

Conclusions 
Stroke after PCI was most frequent during the first 48 hours, in the majority affecting the anterior brain circulation. STEMI was associated with stroke severity. The overall of patients suffered a high number of complications. Some coronary procedure features were more frequent in strokes appearing in the first 48 hours, but larger studies are required to evaluate this association.
