چکیده


مقدمه: بیماری‌های قلبی- عروقی اولین عامل مرگ و میر و مهم‌ترین عامل بستری در بیمارستان در افراد مسن می‌باشد. بنابراین، هدف این مطالعه تعیین میزان بقای کوتاه مدت از سکته‌ی قلبی حاد در بین افراد سالمند بر اساس سن و جنس می‌باشد.

روش‌ها: این مطالعه یک مطالعه‌ی هم‌گروهی مبتنی بر بیمارستان بود که در طی یک دوره‌ی 10 ساله، تمامی بیماران مبتلا به سکته‌ی قلبی حاد با سن بالاتر از 65 سال ساکن اصفهان و نجف‌آباد را مورد بررسی قرار داد. جهت تعیین و مقایسه‌ی میانگین سن بیماران بر اساس گروه‌بندی‌های مختلف، از آزمون آماری t و جهت تعیین میزان بقای بیماران از آزمون آماری Kaplan-Meier و آزمون Log-rank استفاده شد.

یافته‌ها: میزان بقای کلی 28 روزه‌ی بیماران با سن 65 سال و بالاتر، 5/85 درصد بود که این میزان برای مردان برابر با 7/86 درصد و برای زنان برابر با 5/83 درصد بود (001/0 ≥ P). میزان بقا در گروه‌های سنی 74-65 سال، 84-75 سال و 85 سال و بالاتر، به ترتیب برابر با 7/88، 3/81 و 6/75 درصد بود که این اختلاف از نظر آماری معنی‌دار بود (001/0 ≥ P).

نتیجه‌گیری: میزان بقا در زنان از مردان کمتر است و با افزایش سن نیز این میزان به طور مستمر کاهش می‌یابد. بنابراین توجه به زنان و به خصوص افراد با میانگین سنی بالاتر، در ارایه‌ی خدمات درمانی با توجه به خطر بیشتر مرگ و میر در آن‌ها، می‌تواند در بهبود پیامد بیماری مؤثر باشد.
