Risk Profiling for Patients With Isolated or Combined Coronary and Cerebral Ischemia, and Current Management Status

Background: most of available data are designed to show risk profile of either coronary or cerebral ischemia, few data compared both risk profiles or tried to outline risk factors for combined ischemia. The aim is to compare risk profile of isolated coronary, cerebral ischemia or combined disease to find out specific profile for each territory affection. Current management of risk factors will be documented to find out any unmet needs specially for sicker patients with combined ischemia. Material and methods: 3 groups of patients representing coronary, cerebral and combined ischemia.will be studied. Documentation of coronary ischemia will be either by history of coronary care unit admission, ECG documenting an infarction or ischemia, other noninvasive testing, previous coronary intervention or coronary artery bypass grafting. Documentation of cerebral ischemia will be by history, examination for a neurological deficit or any imaging modality documenting cerebral ischemia (brain CT, MRI or duplex whether for extra or intracranial vessels). Risk factor analysis will be for the known risk factors like, age, sex, family history, smoking, recurrent events (like more than one coronary event), sedentary life, waist/hip ratio, BMI, diabetes(history, duration, current medication and current control status, HbA1c), hypertension (history, duration, current drug treatment and current control status). hypercholesterolemia (history, duration, drug treatment and control with current evaluation of LDL, HDL, TG, ApoB/ApoA), hs-CRP, presence of AF( drug treatment). Full patient data will be obtained in a Case Report Form (CRF) based format. CRF format will be designed by the steering committee. Investigators at clinics or centers who agree to share, will be committed to fulfill this CRF and send electronic form to central workstation for database saving. Filling the CRF will be based on a single interview between the investigator and the patient, and any missing data or investigation that mandates another interview will be allowed to complete the CRF within a period of 30 days. Center or investigator agreement will be signed first to be involved in the study and to receive the CRF. All patients will sign a written consent to share in the study. Data analysis will be presented as mean or numbers (%). The significance of relation between qualitative variables will be analysed by chi-square test or Fisher's exact test as indicated. The distribution of means among groups will be analysed by student t testor ANOVA as appropriate. Correlation between quantitative variables will be studied by correlation coefficient. Independent predictors of primary outcomes will be analysed by logistic regression analysis and cox regression analysis as indicated. .
