“…Thus, it is not surprising that increase in LA size and LASF index appear as the strong predictors of unintended cardiovascular events and these unfavorable effects have been demonstrated in population-based cohort studies conducted in the patients with congestive heart failure (19). In patients on dialysis due to renal failure, increase in LV and end-diastolic pressure and diameter gradually enhance LA preload and afterload and heart failure symptoms become more remarkable as a consequence of high atrial pressure (20,21). In the present study, clinical symptoms of congestive heart failure were not present in the patients on regular hemodialysis or peritoneal dialysis and all were in the New York Heart Association Class 1 and 2.…”

Objective: One-quarter of deaths in children with chronic renal failure is due to cardiovascular complications. Conventional echocardiographic methods are insufficient for evaluating systolic functions in children with chronic renal failure. The aim of the present study was to investigate cardiac functions in children with chronic renal failure by evaluating left atrial volume and functions. Methods: The present cross-sectional observational study included 44 children undergoing dialysis, 16 children with chronic renal failure but not yet on dialysis, and 20 healthy control subjects. Transthoracic echocardiography was performed for all children. Variables regarding to left ventricle and atrium (left atrial systolic force, left atrial systolic force index, left atrial volume, left ventricular mass index, and relative wall thickness) were measured using two-dimensional and M-mode echocardiography. Results: Left atrial systolic force index was negatively correlated with systolic blood pressure and left ventricular mass (p=0.01, r=0.266 and p=0.02, r=0.347, respectively). However, it was positively correlated with both early and late diastolic mitral inflow velocity (r=0.518, p=0.001 and r=0.828, p=0.001, respectively). There were no significant difference among the groups in terms of left atrial systolic force index and left atrial volume. However, left atrial systolic force index was higher in children with chronic renal failure but not yet on dialysis. Conclusion: Left atrial systolic force was negatively correlated with systolic blood pressure and left ventricular mass. These findings suggested that evaluating left atrial systolic force and left atrial volume were useful to determine diastolic dysfunction and the necessity of dialysis in patient with chronic renal failure.

“…The longitudinal peak systolic strain and strain rate have been shown to be linearly correlated with the maximum of the LV filling pressure time derivative and also with the peak elastance, which are both global measures of LV systolic function and contractility. 25 The 2-D strain measurement, as determined by speckle tracking, has recently been used for the quantitative evaluation of LV function, and this method has been validated for the evaluation of longitudinal LV function. 26,27 Subclinical LV dysfunction relates to the structurefunction relationship and characterizes a preclinical stage of myocardial damage caused by microvascular ischemia and fibrosis, which is common in systemic hypertension.…”

Circulation Journal Official Journal of the Japanese Circulation Society http://www. j-circ.or.jp he development of left ventricular (LV) hypertrophy in essential hypertension is associated with an increase of LV afterload and severity and duration of the disease process. 1-3 Patients with essential hypertension are exposed to long-lasting pressure overload with enough time for development of pathologic changes in LV structure and function. The morphologic and functional LV changes induced by essential hypertension are well known. 4 Gestational hypertension (GH) is a systemic hypertension that develops during gestation in young women with previously normotensive hearts. Estimation of diastolic dysfunction is usually based on conventional indices that represent the global status. 5 An easily measured Doppler index of myocardial performance, however, combining systolic and diastolic time intervals, has been reported to be simple, reproducible, and independent of heart rate and blood pressure (BP). 6 Moreover, altered segmental contraction based on strain echocardiography may be a sensitive method to evaluate the changes in LV function in GH because it is evident before global conventional indices of systolic dysfunction become definitely informative. 7 Editorial p 1055In the present study we measured and compared LV structure and function in normotensive pregnant women (NPW) with those in patients with GH. The purpose of the present study was to assess the impact of GH on the systolic and diastolic performance and structure of the left ventricle in the previously normotensive young heart.

SummaryBackground: Dyspnea is a common symptom and can be caused by many different conditions. The detection of congestive heart failure (CHF) is sometimes difficult.Hypothesis: The pulse amplitude ratio (PAR) measured by the Finapress procedure during a Valsalva maneuver can detect elevated left ventricular end-diastolic pressure (LVEDP) accurately over a wide range of values.Methods: Comparison of the estimated LVEDP by PAR with the invasively measured LVEDP before and after ventriculography during coronography was made in 101 consecutive stable patients referred for chest pain and/or chronic dyspnea.Results: A significant correlation was found between the catheter-measured LVEDP (range 3-40 mmHg) and the PAR (R 2 = 0.70, p < 0.001). The receiver operator characteristics (ROC) of the PAR to detect an LVEDP > 15 mmHg can be considered to be excellent, with an area under the ROC curve Conclusions: The observed likelihood ratios confirm that the PAR determined by the Finapress procedure may be a useful bedside diagnostic tool in patients with cardiac conditions.
