Correlation Between Relative Handgrip Strength Index as well as Chronotropic Response Index and Heart Rate Recovery Index

Abstract

Introduction: This study evaluated the relationship between relative handgrip strenght index (rHGSi) as well as chronotropic response index (Cri) and heart rate recovery index (HRRi), which are the prognostic parameters of treadmill exercise.Patients and Methods: In total, 490 patients who were recommended to undergo the exercise electrocardiographic test were recruited in this study. The participants were divided into two groups based on both Cri (normal and low CRi groups) and rHGSi (high and low rHGSi groups). Results:The treadmill exercise time, peak heart rate, and metabolic equivalents were higher in the high rHGSi group than in the low rHGSi group. In addition, the 1 st minute HRRi and Cri were higher in the high rHGSi group than in the low rHGSi group. The treadmill exercise time, basal and peak heart rate, metabolic equivalents, and 1 st minute HRRi were significantly lower in the low CRi group than in the normal Cri group. rHGSi was considered an independent predictor of low chronotropic response index. Based on a bivariate analysis, a statistically significant positive correlation was observed between Cri and rHGSi. Similarly, there was a positive association between rHGSi and 1 st minute HRRi. Conclusion:rHGSi might be a practical and effective tool in cardiovascular risk stratification.

“…Aynı zamanda Kİ ile KHR arasında anlamlı ilişki gördük. Öztürk ve arkadaşları yaptıkları çalışmada bizim çalışmamıza benzer şekilde Kİ ve KHR arasında pozitif yönde anlamlı ilişki buldular [14]. Bir başka çalışmada Jae ve arkadaşları, orta yaşlı insanlarda düşük kronotropik indeksin iskemik inme riskini arttırdığını öne sürdüler [15].…”
