[Secondary stroke and its prevention in patients with arterial hypertension]
Insights
Regular medication for hypertension and thrombosis significantly reduces secondary stroke and cardiac infarction risk in patients with arterial hypertension. Adherence to treatment, especially after physician consultation and in rehabilitation centers, improves prognosis.
Area of Science:
- Neurology
- Cardiology
- Geriatrics
Background:
- Ischemic stroke is a significant health concern, particularly in patients with arterial hypertension and cerebral atherosclerosis.
- Secondary strokes carry a higher lethality and lead to more severe disability compared to initial events.
- Arterial hypertension is a major risk factor for both ischemic stroke and cardiac infarction.
Purpose of the Study:
- To analyze the incidence and outcomes of secondary ischemic stroke in patients with arterial hypertension and cerebral atherosclerosis.
- To evaluate the impact of regular antihypertensive and antithrombotic medication on morbidity and mortality in these patients.
- To identify prognostic factors influencing the course of ischemic stroke and associated cardiovascular events.
Main Methods:
- Analysis of 650 patients with ischemic stroke, arterial hypertension, and cerebral atherosclerosis.
- Follow-up studies of patients with secondary stroke (n=50) and primary stroke survivors (n=90) with arterial hypertension.
- Comparison of outcomes between patients receiving regular medication and those not adhering to treatment.
Main Results:
- Secondary ischemic stroke occurred in 25% of cases, with 1.5 times higher lethality and more severe disability than initial strokes.
- In a 1-year follow-up, secondary stroke patients had high rates of recurrent stroke (28%), cardiac infarction (8%), and mortality (22%).
- Regular antihypertensive and antithrombotic medication significantly reduced morbidity and mortality from stroke and cardiac infarction. Primary stroke survivors with regular treatment had significantly lower secondary stroke incidence (8.8%) and mortality (2.2%).
Conclusions:
- Secondary ischemic stroke is a serious complication in patients with arterial hypertension and cerebral atherosclerosis.
- Regular intake of antihypertensive and antithrombotic medications is a favorable prognostic factor, significantly reducing adverse cardiovascular events.
- Patient education and adherence to treatment, particularly in rehabilitative settings, are crucial for improving outcomes and reducing mortality.
Abstract:
An analysis of 650 patients (350 female and 300 male, mean age 70.7 +/- 8.1 years) with ischemic stroke on the background of arterial hypertension and cerebral atherosclerosis revealed that secondary ischemic stroke occurred in 25% of all the cases with lethality 1.5 times higher than in the initial stroke and more severe disability. Follow-up study of 50 patients with secondary stroke on the background of arterial hypertension during 1 year and 8 months showed high rates of stroke (28%) and cardiac infarction (8%) and mortality in both diseases of 22%. In the subgroup of patients, receiving regularly antihypertensive and antithrombotic medications, morbidity and mortality of ischemic stroke and cardiac infarction were significantly lower then in the subgroup without the regular treatment. A regular intake of antihypertensive and antithrombotic medications was considered as a favorable prognostic factor of the disease course. Follow-up (mean 1 year and 1 month) of 90 primary ischemic stroke survivors with arterial hypertension demonstrated significantly lower incidence of secondary stroke (8.8%) and mortality (2.2%). Cases of cardiac infarctions were not observed. Most of the patients began a regular intake of antihypertensive and antithrombotic drugs after physician's secondary consultations and explanations of regular treatment necessity. In rehabilitative centers, patients stick to regular treatment more often.
