Effect of combined antihypertensive and cholesterol lowering treatment on the arterial elasticity in middle-old-aged hypertension patients

Abstract

Objective: To explore the prehospital first-aid mode of acute cardiovascular events, management and patient prognosis. Methods: 378 patients with acute cardiovascular diseases were continuously registered at the emergency department. The patients were divided into two groups according to the different ways of prehospital care, one group included 194 patients who received first-aid care after calling ‘120’, another was a self-aid group consisting of 184 patients whom were taken to hospital by their relatives. The proportion of subjects had higher than high school education level and better knowledge for cardiovascular disease in first-aid group was higher than self-aid group (51.3 vs 28.6%, 81.0 vs 58.7%, both Pb0.05). Firstaid group received a variety of prehospital treatment, but self-aid group not. At hospital two groups were treated according to our standard procedure, then registered, and a questionnaire was taken. All patients were followed up at the end of first and third months. Results: The major cardiovascular events was myocardial infarction (58.8%) among 378 patients, there were statistically significant differences between twogroups in self-aid response time, first disposal time and prehospital rescuing time, respectively [(31.5±5.4) min vs (87.6±8.5) min, (46.1±6.9) min vs (153.9±13.4) min, (61.5±80) min vs (1539±13.4) min, all Pb0.01], but no difference in-hospital rescuing time [(29.5±5.1)min vs (32.7±4.6)min, PN0.05]. Mortality rate was lower in first-aid group than self-aid group at the end of first and thirdmonths (2.6 vs 7.6%, 4.6 vs 9.2%, both Pb0.05). Conclusion:A perfect prehospital emergency management and process can significantly reduce initial disposal time and out-hospital rescuing time of cardiovascular events, and improved the prognosis. The educational level and health knowledge of patients and their families are related to the treatment mode.
