Coexistence of Cerebral and Coronary Atherosclerosis in Acute Ischemic Cerebrovascular Disease Patients Registry

Study Overview
=================
Brief Summary
-----------------
Coexistence of Cerebral and Coronary Atherosclerosis in Acute Ischemic Cerebrovascular Disease Patients Registry (CoCCA) is a single-center observational registry of patients hospitalized for acute ischemic cerebrovascular disease (AICVD) with atherosclerotic changes in both cerebral and coronary arteries. This registry aims to establish quantified risk stratification and prognostic models, as well as suggest effective diagnostic and therapeutic strategies.

Detailed Description
-----------------
Atherosclerosis has exerted huge global burden as the common pathological process underlying ischemic heart disease and cerebrovascular disease. A substantial portion of acute ischemic cerebrovascular disease (AICVD) patients have both cerebral and coronary atherosclerosis, which is an omen of poor outcomes. But there is large evidence gap in these high-risk patients' prognosis-related factors, limiting the improvement of care quality. Coexistence of Cerebral and Coronary Atherosclerosis in Acute Ischemic Cerebrovascular Disease Patients Registry (CoCCA) is a single-center prospective observational registry of patients hospitalized for AICVD with atherosclerotic changes in both cerebral and coronary arteries. This registry aims to establish quantified risk stratification and prognostic models, as well as suggest effective diagnostic and therapeutic strategies. The clinical, imaging and laboratory information will be collected at the baseline. During an estimated 5-year follow-up, the vessel-related diagnostic or monitoring procedures, treatment, functional status and new vascular events will be recorded by web-based patients' self-reports, investigators' regular telephone visits.
