Local arterial wave speed, a surrogate of vessel stiffness, can be estimated via the pressure-velocity (PU) and diameter-velocity (ln(D)U) loop methods. These assume negligible early-systolic reflected waves (RWes) and require measurement of cross-sectionally averaged velocity (U<sub>mean</sub>), which itself is a valuable quantity related to volumetric blood flow. However, RWes may not always be negligible and routine Doppler ultrasound typically provides maximum velocity waveforms or estimates of mean velocity subject to various errors (U<sub>raw</sub>)...

BACKGROUND: Direct layngoscopy and endotracheal intubation is a noxious stimuli and induces sympathomimetic responses. Although well tolerated in healthy subjects, it may impose life threatening arrhythmias, left ventricular failure or rupture of cerebral aneurysm in susceptible patients. Esmolol, Labetalol and Lignocaine attenuate these responses but are associated with side effects of bradycardia, hypotension etc. In lower doses, chances of these side effects are comparatively low. So we designed this prospective clinical trial to assess the efficacy of intravenous esmolol, labetalol and lignocaine in low doses for attenuation of sympathomimetic responses to endotracheal intubation...

INTRODUCTION: Cardiovascular (CV) reactivity to psychological stress has been implicated in the development and exacerbation of cardiovascular disease (CVD). Although high CV reactivity traditionally is thought to convey greater risk of CVD, the relationship between reactivity and clinical outcomes is inconsistent and may depend on the patient population under investigation. The present study examined CV reactivity in patients with heart failure (HF) and its potential association with long-term clinical outcomes...

There is good evidence that controlling hypertension reduces the risk of stroke and other cardiovascular consequences of hypertension. The recent Systolic Blood Pressure Intervention Trial (SPRINT) trial, stopped early because of a higher risk among participants randomized to the higher blood pressure target, will no doubt lead to calls for even lower pressures. Even among participants age ≥75, those randomized to a target systolic blood pressure (SBP) < 120 mmHg had a lower risk of stroke and cardiovascular events compared with a SBP target <140 mmHg[1]...
