Objective: To determine the incidence of stroke, overall and by sub-types, in Peru between 2017 and 2018. Materials and Methods: Analysis of hospital morbidity data obtained from SUSALUD (open data). Using the ICD-10 codes, the following were studied: subarachnoid hemorrhage (I60), atraumatic intracerebral hemorrhage (I61), cerebral infarction (I63), and unspecified stroke (I64). The crude and age-standardized incidence was calculated according to the population of the World Health Organization and using the national projected population number of people according to year, age and sex as the denominator. Results: In 2017, a total of 10,570 stroke cases were recorded, whereas, in 2018, there were 12,835 cases. Ischemic events were more frequent in both years. Regardless of stroke subtype and year, men were more affected than women. In the 35+ year-old population, an increase in the crude incidence of total stroke was observed between 2017 and 2018, from 80.9 to 96.7 per 100,000 person-years. The age-standardized incidence showed the same trend, but in a greater magnitude: from 93.9 to 109.8 per 100,000 person-years. Ischemic stroke was the one that increased the most, with an age-standardized rate in people aged 35+ years of 35.2 in 2017 and 46.3 per 100,000 person-years in 2018. Conclusions: The incidence of stroke is high in Peru. Ischemic cases are the most frequent and they disproportionately affect men. Our results suggest the need for a surveillance system to robustly quantify the incidence of these cases and understand their determinants.
