Background and Purpose:
CVA refers to a sudden decrease in cerebral functioning due to disordered supply of blood to brain tissues. cerebrovascular disease stand third to cardiac and cancerous diseases in mortality rates in developing countries. Their total prevalence are 794 in 100/000.in the united states,750/000 experience a new or recurrent CVA every year. Around 1/3 of ischemic strokes occur due to cardiogenic emboli. Risk factors to CVA include cardiac disorders(MI, emboli, arrhythmia, Coronary artery disorders, left ventricular hyperfrophy, congested cardiac deficiency),diabetes, atherosclerotic cerebral vessels, hypertension, polysythemia , hyper cholesterolemia, smoking, contraceptives, emotional stress, obesity, CVA familial history, age and race. Regarding the high CVA risks and causes and high cost of treatment and care, mortality and debilities, obtaining statistical data on CVA cardiac risk factors seems necessary for planning to prevent CVA and its consequences, as today in developed countries extensive planning is carried out for the prevention of CVA. Method:
This descriptive analytical study started with 152 CVA admissions in 2005-2006 at vasei Hospital in Sabzevar/Iran. A questionnaire in four parts-demographic and medical history ,tests, cerebro-nervous diagnostic procedures and cardiac diagnostic procedures-was given for data collection. After a definite CVA diagnosis and excluding cortical atrophy and non CVA samples,100 CVA cases were investigated.
Data were analyzed in spss using descriptive statistics Results:
43 men and 57 women were studied.84%were over 60 years old with a mean age of 69.95 years.52 were rural and 48 urban dwellers. Highest incidence related to the ranges 75-84 and 65-74 years.78% had a history of hypertension.70% indicated changes in arrhythmia and blook in EKG.87% of CVA were ischemic.26% had cardiomegaly.39% had a systolic blood pressure of over140 and 18% diastolic blood pressure of over 40.
ECO results indicated that 49% of the patients suffered from hypokinesia in various cardiac sites.Also,60% showed EF less than 40.But 21% suffered from cardiac valvular disorders. The prevalence of disorders in left ventricular functioning and ischemic cardiac diseases were 31% and 22% respectiuely
