Predictors of impaired heart rate variability and clinical outcome in patients with acute myocardial infarction treated by primary angioplasty

Abstract

Our study shows that, in AMI patients treated by primary PCI, a delay in coronary revascularization and AMI extension are key factors for determining depressed HRV.

Effects of percutaneous coronary intervention on the ambulatory blood pressure of patients with hypertension and coronary heart disease

“…PCI can effectively relieve stenosis in the coronary artery and remove the occlusion of coronary arteries in a timely manner so as to achieve myocardial reperfusion and reduce myocardial ischemia. Consequently, myocardial function is restored, the sympathetic activity is reduced, and the vagal tone is increased; these phenomena all lead to improved [8,13,14]. In this study, we monitored the HRV of each patient and found no significant difference between the HRV indices at the before and after PCI.…”

Improvement of heart rate variability after decreased insulin resistance after sleeve gastrectomy for morbidly obesity patients

“…With the development of computer-based analytical tools, researchers can perform in-depth assessments of HRV, including the analysis of both linear and nonlinear parameters [25]. Previous studies have noted that decreased HRV is associated with poor outcomes in patients with cardiac diseases [26][27][28]. Currently, HRV analysis is considered to be a well-developed measure of cardiovascular disease outcomes and a useful tool for understanding the status of the ANS.…”

“…Currently, the HRV indexes have been used to understand various conditions, such as coronary artery disease [54][55][56][57], cardiomyopathy [26.58], arterial hypertension [29,[59][60][61], myocardial infarction [62][63][64], sudden death [65], chronic obstructive pulmonary disease [2,66,67], renal failure [68], heart failure [69], diabetes [70], stroke [71], Alzheimer's disease [72] leukemia [73], obstructive sleep apnea [74], epilepsy [75], headache [76], among others.…”

“…Table 2 shows studies using HRV in various physiological and pathological conditions. Carnethon et al [56] Novais et al [29] Menezes et al [60] Terathongkum et al [61] Takahashi et al [55] Bittencourt et al [26] Pecyna [63] Carney et al [54] Limongelli et al [58] Karas et al [59] Larosa et al [62] Javorka et al [38] Catai et al [7] Weerapong et al [41] Mello et al [37] Paschoal et al [72] Sin DD et al [66] Kudaiberdieva et al [65] Lopes et al [71] Neves et al [73] Furuland et al [68] Lopes et al [79] and Paschoal et al [80] observed that the aging process causes a depletion of vagal tone and consequent increase in sympathetic activity, therefore older individuals have a lower HRV. In 2006, Rajendra Acharya et al [4] observed that HRV is lower with age and the variation is greater in women.…”
