چکیده

مقدمه: مطالعات متعددی در جوامع مختلف دو شاخص تعداد ضربان قلب در دقیقه‌ی اول بعد از پایان تست ورزش (1 Minute Heart Rate Recovery یا HRR) و ظرفیت ورزش (Exercise Capacity یا EC) را به عنوان پیش‌گویی کننده‌های بروز حوادث قلبی نشان داده است. مطالعه‌ی حاضر جهت مقایسه‌ی این دو شاخص در افراد با و بدون سندرم متابولیک در شهرستان اصفهان انجام گرفت.روش‌ها: این مطالعه بر روی 254 نفر از افراد غیر مبتلا و 216 فرد مبتلا به سندرم متابولیک از مطالعه هم‌گروهی اصفهان انجام شد. اطلاعات دموگرافیک، دور شکم، فشار خون، قد و وزن افراد ثبت شد. تری‌گلیسرید سرم و قند خون ناشتا، کلسترول تام، HDL و LDL افراد نیز اندازه گیری شد. تست ورزش بر اساس پروتکل استاندارد  Bruceانجام گردید و تعداد ضربان قلب در دقیقه‌ی اول و ظرفیت ورزش تعیین و ثبت شد. داده‌ها به کمک نرم‌افزار آماری 15SPSS و بااستفاده از روش Generalized linear model با تعدیل بر اساس سن تجزیه و تحلیل شد.یافته‌ها: تعداد ضربان قلب در دقیقه‌ی اول در گروه غیر مبتلا بیشتر از گروه مبتلا به سندرم متابولیک بود (007/0 = P) اما در هر دو گروه میزان تعداد ضربان قلب در دقیقه‌ی اول طبیعی بود (بیشتر از 18 ضربان در دقیقه). میزان ظرفیت ورزش در گروه مبتلا به سندرم متابولیک به طور معنی‌داری کمتر از گروه غیر مبتلا بود (022/0 = P).نتیجه‌گیری: با توجه به یافته‌ها، این مطالعه توجه پزشکان و برنامه‌ریزان بهداشتی جامعه‌ی ما را به ارتباط قوی‌تر ظرفیت ورزش با سندرم متابولیک در مقایسه با تعداد ضربان قلب در دقیقه‌ی اول معطوف می‌دارد؛ نیاز به تعیین نقطه‌ی معیار جدید جهت تعداد طبیعی ضربان قلب در دقیقه‌ی اول نیز وجود دارد.

چکیده [English]

Background: Many studies showed that heart rate recovery (1 min) and exercise capacity at exercise test are both strong predictors of cardiovascular events in various populations. This study compared heart rate recovery (1min) and exercise capacity in individuals with and without metabolic syndrome in Iranian community.Methods: This cross-sectional study was performed on 470 individuals aged ≥ 35 years who followed in Isfahan Cohort Study. A questionnaire including questions on demographic and lifestyle information as well as weight, height, blood pressure, and waist circumference was completed. Triglyceride, fasting blood glucose (FBS), total cholesterol, HDL, and LDL levels were measured as well. All subjects performed a symptom limited exercise test under the standard Bruce protocol. Heart rate recovery (1 min) and exercise capacity were calculated. Data were analyzed by generalized linear model SPSS15 software.Finding: The prevalence of diabetes mellitus, hypertension, and dyslipidemia were higher in individuals with metabolic syndrome (P = 0.001). Heart rate recovery (1 min) was in normal range in individuals with and without metabolic syndrome (> 18 bpm) but in subjects without metabolic syndrome it was higher (41.48 versus 37.07; P = 0.007). There was no difference between men and women in individuals with and without metabolic syndrome (P = 0.645 and 0.39 respectively). Exercise capacity was lower in individuals without metabolic syndrome (P = 0.022).Conclusion: Our findings suggested that among exercise capacity and heart rate recovery, this is exercise capacity which has a stronger relationship with metabolic syndrome in our community. Also, it seems that there is a need for reconsideration on heart rate recovery threshold.
