Amlodipine is a classical drug with varied properties extending from control of blood pressure to as an antianginal and anti atherosclerotic agent. Amlodipine is a longer acting dihydropyridine calcium channel blocker, effective for 24 hours BP control and cause no BP variability. It is a powerful, well-tolerated, and safe antihypertensive agents that is widely used either alone or as a key component of combination therapy for hypertension. Its effective BP reduction has shown proven benefits in cardiovascular event reduction that is supported with strong evidences from large randomised controlled trials...

Quantification of spatial and temporal variations in premature mortality attributable to PM2.5 has important implications for air quality control in South and Southeast Asia (SSEA). The number of PM2.5 -induced premature deaths during 1999-2014 in SSEA was estimated using an integrated exposure-response model based on 0.01° × 0.01° satellite-retrieved PM2.5 data, population density, and spatially and temporally variable baseline mortality data. The results showed extremely high premature death rates in North India and Bangladesh...

PURPOSE: Previous studies have suggested that extreme endurance exercise may induce cardiac micro-damage that could lead to subsequent myocardial fibrosis. Soluble suppression of tumorigenicity (sST2) is a cardiac biomarker for assessment of myocardial fibrosis, inflammation and strain. We evaluated baseline and exercise-induced sST2 concentrations in a heterogeneous cohort of marathon runners to identify predictors for sST2 concentrations. METHODS: Ninety-two runners supplied demographic data, health status, physical activity levels and marathon experience...

Processing of sound signals is an important factor for conscious human communication and such sound signals may be assessed through cortical auditory evoked potentials. Heart rate variability provides information about heart rate autonomic regulation. The association between resting heart rate variability and cortical auditory evoked potentials was investigated. Resting heart rate variability in the time and frequency domain and the cortical auditory evoked potential components were investigated. Subjects remained at rest for 10 minutes for recording of heart rate variability...

Rating of perceived exertion (RPE) extrapolation involves mathematically extending the submaximal relationship between RPE and oxygen consumption (VO2 ) to maximal intensity. This technique allows practitioners to forego, potentially dangerous, maximal exertion testing while attaining accurate measures of maximal oxygen consumption used for exercise prescription. This method has been proven accurate in adults, but much less in known when applied to an adolescent population. The purpose of this study was to assess the accuracy of the RPE extrapolation as method for estimating VO2max in adolescents...

Background: The time variation between consecutive heartbeats is commonly referred to as heart rate variability (HRV). Loss of complexity in HRV has been documented in several cardiovascular diseases and has been associated with an increase in morbidity and mortality. However, the mechanisms that control HRV are not well understood. Animal experiments are the key to investigating this question. However, to date, there are no standard open source tools for HRV analysis of mammalian electrocardiogram (ECG) data and no centralized public databases for researchers to access...

BACKGROUND: Individuals with schizophrenia are at increased risk of relapse when they live in highly critical (i.e., high expressed emotion; EE) family environments. It remains less clear, however, how individuals at elevated risk for a psychotic disorder react to the social stress of EE. Here we examined whether individuals at elevated risk for developing schizophrenia report greater subjective changes in affect and have increased physiological reactivity after hearing critical, praising and neutral comments...

BACKGROUND AND OBJECTIVE: Paroxysmal Atrial Fibrillation (PAF) is one of the most common major cardiac arrhythmia. Unless treated timely, PAF might transform into permanent Atrial Fibrillation leading to a high rate of morbidity and mortality. Therefore, increasing attention has been directed towards prediction of PAF, to enable early detection and prevent further progression of the disease. Notwithstanding the pharmacological and electrical treatments, a validated method to predict the onset of PAF is yet to be developed...

Heart rate variability (HRV) is a tool that has been extensively used in fields such as clinical cardiology, psychiatry, and psychology to assess affective experiences. Although traditionally The European Society of Cardiology and The North American Society of Pacing and Electrophysiology recommended to use either a recording length of 24-h (long-term) or five minutes (short-term), recent advances in the field have suggested the use of ultra-short term (<5 min) HRV measurements. In this study, we investigated whether ultra-short term HRV measurements can be used to investigate the temporal dynamics of experimentally induced emotions using pictures from the International Affective Picture System...

Background Hydrotherapeutic applications to the head and spine have shown to improve cardiovascular and autonomic functions. There is lack of study reporting the effect of either neutral spinal bath (NSB) or neutral spinal spray (NSS). Hence, the present study was conducted to evaluate and compare the effects of both NSB and NSS in healthy volunteers. Methods Thirty healthy subjects were recruited and randomized into either neutral spinal bath group (NSBG) or neutral spinal spray group (NSSG). A single session of NSB, NSS was given for 15 min to the NSBG and NSSG, respectively...

To investigate the heart rate during cardio-pulmonary exercise (CPX) testing in individuals with type 1 diabetes (T1D) compared to healthy (CON) individuals. Fourteen people (seven individuals with T1D and seven CON individuals) performed a CPX test until volitional exhaustion to determine the first and second lactate turn points (LTP1 and LTP2 ), ventilatory thresholds (VT1 and VT2 ), and the heart rate turn point. For these thresholds cardio-respiratory variables and percentages of maximum heart rate, heart rate reserve, maximum oxygen uptake and oxygen uptake reserve, and maximum power output were compared between groups...

The present study was conducted to clarify multiple cardiohemodynamic and electrophysiological properties including inotropic/lusitropic effects of nifekalant, a class III antiarrhythmic drug, in an isoflurane-anesthetized monkey. Nifekalant was administered intravenously at the therapeutic dose of 0.3 mg/kg over 10 minutes to male cynomolgus monkeys (n=4), followed by higher dose of 1 (n=3) or 3 mg/kg (n=1) that was limited due to arrythmogenicity. Left ventricular (LV) pressure-volume (PV) analysis revealed that the 0...
