بررسي ارتباط بين شدت درد قفسه سينه با شاخص‌هاي فيزيولوژيك در بيماران مبتلا به بيماري شريان كرونر

Relationship between chest pain severity and physiological indexes in patients with coronary artery disease

زمینه و هدف: ارزیابی درد قفسه سینه عاملی مهم در بیماری عروق كرونر می‌باشد. از این‌روی این مطالعه با هدف تعیین ارتباط بین شدت درد قفسه سینه با شاخص‌های فیزیولوژیك در بیماران مبتلا به بیماری شریان كرونر انجام شد. روش بررسی: مطالعه به صورت توصیفی تحلیلی روی 80 بیمار بستری در بخش مراقبت ویژه قلبی بیمارستان دكتر مفتح ورامین در محدوده زمانی فروردین تا شهریور ماه سال 1393 انجام شد. در این مطالعه، ارتباط بین شدت درد قفسه سینه بیماران و شاخص‌های فیزیولوژیك مورد بررسی قرار گرفت. یافته‌ها: میانگین سنی بیماران 79/13±13/60 سال بود. میانگین شدت درد در بیماران برابر با 14/2±51/6 بود. یافته‌های مطالعه ارتباط معناداری بین میانگین شدت درد و شاخص‌های فیزیولوژیك بیماران نشان نداد (05/0

Background: Coronary artery disease is considered as main factor for patients’ hospitalization. Chest pain is the most common symptoms of patients and its assessment is an important factor in coronary artery disease. So, this study aimed to determine the relationship between the severity of chest pain with physiological indexes in patients with coronary artery disease. Methods: This study was a descriptive-analytical design that performed on 80 patients with that were hospitalized in coronary care unit of Shahid Mofatteh Hospital in Varamin city, Iran, from March to September, 2014. In this study, the relationship between the chest pain severity and blood pressure, pulse rate, respiratory rate, O2 saturation and ST segment alterations were assessed. Finally, the gathered data were analyzed by descriptive and inferential statistics. Results: The mean of chest pain severity was 6.51±2.14 in patients. Patients’ age was between 26 to 85 years old and the mean of age was 60.79±13.79 and there was no significant correlation between age and chest pain severity (P=0.985). Also male and female patients were equal. There was no significant difference between chest pain severity of men and women (P=0.471). The findings of study showed no correlation between chest pain severity and heart rate (r=-0.174 and P=0.122), respiratory rate (r=-0.013 and P=0.909), O2 saturation (r=0.051 and P=0.651), ST segment alterations (r=0.07 and P=0.539). Also, there was no significant difference between chest pain severity and systolic pressure (P=0.353), diastolic blood pressure (P=0.312) and body mass index (P=0.256) among patients. Conclusion: In this study, there were not enough evidences for relation between chest pain and physiological indexes in patients with coronary artery disease. So performing more studies in another settings and conditions recommended.
