“…All chamber quantification was aligned with the American Society of Echocardiography [9]. LV end-diastolic volume (LVEDV) and LV end-systolic volume (LVESV), which were measured from the apical 4-and 2-chamber views using Simpson's biplane method, were indexed by the body surface area to obtain LVEDV index (LVEDVi) and LVESV index (LVESVi) [10].…”

“…This implies that echocardiography may fill the diagnostic void in risk stratification. Several parameters have been reported useful in prognostication in AF, such as E/e', LAVi, and LVH [6,9,[22][23][24][25]. Nonetheless, these indicators have not been tested directly against CHA 2 DS 2 -VASc score.…”

“…Early mitral inflow velocity (E) was measured with the pulsed wave Doppler method by placing the sample volume at the level of the mitral valve leaflet tips. The tissue Doppler-derived diastolic mitral annular velocity (e') was measured from the septal corners of the mitral annulus in the apical four-chamber view 17) .…”

Aim:To determine whether there is a significant correlation between optic nerve head circulation determined by pulse wave analysis of laser speckle flowgraphy (LSFG), and the cardio-ankle vascular index (CAVI), left ventricular (LV) function, and age. Methods: Forty-nine men who visited the Vascular Function Section of Toho University Sakura Medical Center, Chiba, Japan were studied. The mean age of the subjects was 60.7±10.6 years (range 29 to 80 years). The CAVI, left ventricular ejection fraction (LVEF) as a function of the systolic LV function, early diastolic mitral annulus velocity (e'), and the ratio of transmitral early peak velocity (E) to e' (E/e' ratio) as the diastolic LV function, and the optic nerve head circulation determined by pulse wave analysis of the LSFG. This parameter was named the blowout time (BOT). Results: The BOT was significantly correlated with age, heart rate, body mass index (BMI), triglyceride, LVEF, e' velocity, E/e' ratio, and CAVI. The results of multiple regression analysis showed that age was significantly associated with CAVI (r = 0.36, p= 0.002), BOT (r =−0.30, p= 0.01) and e' velocity (r =−0.21, p= 0.04). Conclusions:The BOT of the optic nerve head circulation determined by LSFG was significantly correlated with age but was independent of cardiac diastolic function and arterial stiffness. This suggests that the damage to different organs increases with age. Our results confirmed that BOT can be helpful in evaluating physiological aging of the microcirculation.

“…Likewise, several transthoracic echocardiographic parameters have shown promising value in the prediction of stroke/thromboembolism [50][51][52][53][54] or surrogate markers of stroke [55][56][57][58][59]. These include left atrial (LA) size measured on M-mode [50], indexed LA volume [51], left ventricular ejection fraction [57], E/E 0 ratio [52] and peak systolic LA strain rates assessed through speckletracking [54].…”

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and a major preventable cause of stroke and hospitalization. Its prevalence is on the rise worldwide and experts believe it will continue to rise for the foreseeable future, due to the ageing population and increased survival from conditions associated with AF. Despite the fact that oral anticoagulation is effective in preventing strokes due to AF, there is extensive evidence suggesting this therapy remains underused. Barriers to the prescription of anticoagulation include patients' age per se, comorbidities, inadequate risk stratification, perceived risk of falls and bleeding, and the difficulty in achieving a stable international normalized ratio (INR) on warfarin. Also, asymptomatic patients with AF may not be identified and therefore not be candidates for anticoagulation. Physicians need continued better education on the identification of patients at risk of stroke and management of oral anticoagulation. This article reviews the barriers to anticoagulation in patients with AF in the United Kingdom and considers how those barriers may be overcome.
