Association between hypertension and stroke recurrence in Sultan Agung Islamic Hospital Semarang

Introduction: Recurrent strokes can occur immediately, months, or years after the first attack. One of the most common risk factors for this occurrence is hypertension. This study aims to determine the relationship between hypertension and the occurrence of recurrent strokes. Methods: This observational analytical study uses a case-control study approach with a sample size of 70 patients, divided into 35 patients in the case group and 35 patients in the control group which were selected using a total sampling technique. Data were collected through the patient medical records at Sultan Agung Islamic Hospital Semarang and then analyzed using the Chi-Square test and Odds Ratio (OR) to determine the relationship between the risk of hypertension and the occurrence of recurrent stroke. Result: The research results show that in the case group, 30 patients (85.7%) experienced recurrent strokes with hypertension, and 5 patients (14.3%) experienced recurrent strokes without hypertension. The hypothesis test results in this study obtained a p-value of 0.029 (p<0.05) and OR = 3.545 (CI 95% = 1.102 – 11.411). Conclusion: Hypertension has a significant relationship with the occurrence of recurrent stroke, with a risk of 3.545 times higher for experiencing recurrent stroke compared to stroke patients without hypertension. Therefore, patients with hypertension require hypertension management to prevent recurrent stroke events.
