Characteristics of stroke inpatients in a single- center in Kunming: A multi-ethnic settlement with a northern sub-tropical low-latitude plateau mountain monsoon climate

Abstract

Objective: This study aimed to evaluate the characteristics of stroke inpatients in Kunming in southwest China. Methods: Basic demographic information and risk factors of stroke inpatients admitted to a first-rate tertiary referral hospital in Kunming from January 1, 2015, to September 15, 2022, were retrospectively analysed. In total, 7,108 stroke inpatients with ischemic stroke (IS), primary intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH) were included. Results: IS was the most common type of stroke (75.97%), followed by ICH (13.45%) and SAH (10.58%). There were significant differences among the three groups in sex, age, ethnic, residence, occupation, and medical expenses (P<0.05). There was also a statistically significant difference in the proportion of inpatients between the four seasons (P<0.05). Hypertension, dyslipidemia, and diabetes were common risk factors for stroke. There were significant differences in the incidence of smoking, alcohol use, hypertension, dyslipidemia, diabetes, atrial fibrillation, and pulmonary infection among the three stroke subtypes (P<0.05). Conclusion: Demographic information and risk factors were different among the three stroke subtypes. The number of hospitalized patients from all three groups varied slightly in different seasons in Kunming. Different types of cerebrovascular disease patients in the region have different characteristics from demographic information to risk factors.
