Left ventricular hypertrophy: a comparison among Kurdish patients with first-ever ischemic versus first-ever hemorrhagic stroke.

BACKGROUND AND AIM Left ventricular hypertrophy (LVH) has been proposed to be associated with an increased risk of stroke. We compared the prevalence of LVH among patients with first-ever ischemic versus first-ever hemorrhagic strokes. MATERIAL AND METHODS This observational study, which was conducted at the Sulaimaniya general teaching hospital from November 2009 to March 2012, involved 100 consecutive patients with their first-ever stroke. Fifty patients had ischemic stroke while the rest (n = 50) developed hemorrhagic stroke. The presence of LVH was detected using transthoracic echocardiography and a comparison with respect to its prevalence between the 2 aforementioned groups was made. RESULTS The mean age of patients in the hemorrhagic group was 61.7 +/- SD 11.2 years while in the ischemic group it was 63.9 +/- SD 6.1 years. Out of 100 patients, 66 (66%) patients were males (31 in the hemorrhagic group and 35 in the ischemic group) while the rest (n = 34; 34%) were females (19 in the hemorrhagic group and 15 in the ischemic one). Ninety one (91%) patients were hypertensive (47 in the hemorrhagic group and 34 in the ischemic group). Fifty three (53%) out of 100 patients demonstrated LVH (31 in the hemorrhagic group and 22 in the ischemic group). A head-to-head comparison between the two groups with respect to gender demonstrated no statistically significant difference in terms of the presence of LVH among patients with hemorrhagic versus ischemic strokes; males (P value < 0.26; 95% CI 3.4-39.3); females (P value < 0.43; 95% CI 16.7-43.8). However, a univariate analysis after correction for age and gender revealed a statistically significant difference between these groups (P-value < 0.001; 95% CI 2.7-46.2). CONCLUSION LVH was more common in Kurdish patients with first-ever hemorrhagic stroke than in those who had sustained their first-ever ischemic stroke. Further analytic studies are required to clarify the prevalence of LVH in patients with ischemic stroke.
