Аннотация
BACKGROUND: It has been clearly demonstrated that hypertension and one of its main evoked effects, cardiac hypertrophy, are independent risk factors for ischemic stroke. However, the ischemic brain lesions can further be affected by a second wave of injury characterized by hemorrhagic transformation (HT) of the primary ischemic lesion, which significantly aggravates the clinical outcome. So far, the risk factors that could affect such a transition in hypertensive patients are still unclear.
METHODS: In this study, we investigated whether in hypertensive patients the concomitant presence of cardiac hypertrophy can affect the transition of ischemic brain lesions toward HT.
RESULTS: Our analysis was focused on a population of hypertensive patients admitted to our Acute Stroke Unit. The hypertensives with acute ischemic stroke suffering of HT were 18% of the sample. In these latter, the prevalence of cardiac hypertrophy was significantly lower than in those spared by HT as also shown by the levels of left ventricular mass index (LVMI) that were significantly higher in patients spared by HT. More important, cardiac hypertrophy was protective even from symptomatic HT.
CONCLUSION: Here we show that hypertensive patients with cardiac hypertrophy have less probability to develop HT during an acute episode of ischemic stroke. These results could help to identify patients with lower risk of spontaneous HT and that could have better beneficial effects from thrombolytic therapy during acute ischemic stroke.
