Introduction: Cardiomyopathies are diseases of heart muscle that may originate from genetic defects, cardiac myocyte injury or infiltration of myocardial tissues. Dilated cardiomyopathy is the most common phenotype and is often a final common pathway of numerous cardiac insults. Mostly it remains unknown in the absence of echocardiography, histopathology and genetic evaluation. Though common it is underdiagnosed with not much of data available in our setup.Methods: This study was analytical cross-sectional study of hospital data on Echocardiographic findings in 65 patients of DCM visiting cardiology unit for Echocardiographic evaluation from 1st of February to 31st July 2018 for the period of six months in Shree Birendra Hospital, a tertiary care military hospital at Chhauni, Kathmandu. Pediatric age group patients and those who refused to give consent were excluded. Data obtained were entered in Microsoft Excel 2010 and analyzed by IBM SPSS 21.Results: Among 65 patients enrolled 40 (61%) were male and 25 (39%) female with male to female ratio of 1.6:1. Elderly people (61-75 years) with an average age of 65 were commonly involved and they presented mostly with congestive heart failure, 32 (49%). Echocardiographic evaluation showed 36 (55%) with mildly dilated Left Ventricle (5.6-6.0cm). Majority had reduced Left ventricular systolic function with an average Ejection fraction (EF) of 39.6%. No significant difference between male and female with the average EF% (P=0.990) and there was no significant relation between age and average EF% (P=0.091).Conclusions: Dilated Cardiomyopathy is the commonest cardiomyopathy phenotype mostly presenting with congestive heart failure. It is often underdiagnosed in our part of the world, however echocardiography will easily detect the condition. Keywords: dilated cardiomyopathy; echocardiography; ejection fraction; left ventricle.

Background: Congestive heart failure (CHF) is a chronic disease that incidence is growing in the population. Vitamin D effects on directly myocardial cells. The aim of this study was to investigate the association between vitamin D levels with ejection fraction of left ventricle. Methods: The study population consisted of 101 patients admitted with heart failure. Age, gender, and demographic characteristics (diabetes mellitus, hypertension, smoking-nonsmoking, coronary artery disease) of all patients were recorded. In all patients for blood analyses vitamin D, creatine, crp and lipid profile were studied. And all patients were studied echocardiography. Results: CHF patients, in our population 35 (34.7%) patient is female and 66 (65.3%) patient is male. The mean age of our patients was calculated as 67.4±12.9 years. Our patients laboratory parameters mean were measured for vitamin D 24.3±17.3 ng/ml. Left Ventricular Ejection Fraction (LVEF) mean was measured 31.8±9.5. In our study group LVEF and vitamin D was correlated with each other Conclusion: Vitamin D and LVEF had a positive correlation in heart failure patients. It may be occured with the protective effect of vitamin D or consequence of hipovitaminosis. J Pharm Care 2020; 8(2): 50-52.

This systematic review is based on 19 studies from Elsevier, PubMed, Embase, and Scopus databases, which were found by the following keywords: LA strain (left atrial strain), STE (speckle tracking echocardiography), HF (heart failure), and HFpEF (heart failure with preserved ejection fraction). The review focuses on results and conclusions of studies on using the 2D echocardiographic evaluation of left atrial (LA) myocardial strain for early diagnosis of HFpEF in routine clinical practice. Analysis of the studies included into this review showed a significant decline of all LA functions in patients with HFpEF. Also, multiple studies have reported associations between decreased indexes of LA strain and old age, atrial fibrillation, left ventricular hypertrophy, left and right ventricular systolic dysfunction, and LV diastolic dysfunction. Thus, the review indicates significant possibilities of using indexes of LA strain in evaluation of early stages of both systolic and diastolic myocardial dysfunction. Notably, LA functional systolic and diastolic indexes are not sufficiently studied despite their growing significance for diagnosis and prognosis of patients with HFpEF. For this reason, in addition to existing models for risk stratification in this disease, including clinical characteristics and/or echocardiographic data, future studies should focus on these parameters.

Abstract Ischemic heart disease is a major causes of heart failure. Heart failure patients have predominantly left ventricular dysfunction (systolic or diastolic dysfunction, or both). Acute heart failure is most commonly caused by reduced myocardial contractility, and increased LV stiffness. We performed echocardiography and gated SPECT with Tc99m MIBI within 263 patients and 166 normal individuals. Left ventricular end systolic volume (LVESV), left ventricular end diastolic volume (LVEDV), and left ventricular ejection fraction (LVEF) were measured. For all degrees of ischemia, there was a significant difference between ejection fraction values measured by SPECT and echocardiography, and there were no significant differences among end systolic volume and end diastolic volume value calculated by two methods for all cases. The mean value for EDV (ECHO)/EDV (SPECT) was 1.07 ± 0.31 for degree (1, 2); in the degree 3 the mean value was 1.02 ± 0.08, and 1.005 ± 0.07 for degree 4. The mean value for ESV (ECHO)/ESV (SPECT) was 1.08 ± 0.34 for degree (1, 2); while 1.03 ± 0.12, 1.021 ± 0.128 for degree 3 and 4 respectively. This study was showed a good relation between left ventricular size and ejection fraction measured by SPECT with Tc99m, and echocardiography.

Background: BNP testing is now common though it is not clear if the test results are used to improve patient care. A high BNP may be an indicator that the left ventricular ejection fraction (LVEF) is low (<40%) such that the patient will benefit from life-prolonging therapy. Objective: To determine how often clinicians obtained a measure of LVEF (echocardiography, nuclear) following a high BNP value when the left ventricular ejection fraction (LVEF) was not known to be low (<40%). Methods and Results: We reviewed the medical records of 296 consecutive patients (inpatient or outpatient) with a BNP values of at least 200 pg/ml at a single medical center (tertiary hospital with 8 community clinics). A prior diagnosis of heart failure was made in 65%, while 42% had diabetes, 79% had hypertension, 59% had ischemic heart disease and 31% had chronic lung disease. The mean age was 73 ± 12 years, 75% were white, 10% black, 15% other and the mean BNP was 810 ± 814 pg/ml. The LVEF was known to be < 40% in 84 patients (28%, mean BNP value of 1094 ± 969 pg/ml). Of the remaining 212 patients without a known low LVEF, 161 (76%) had a prior LVEF >=40% ( mean BNP value of 673 ± 635 pg/ml), and 51 (24%) had no prior LVEF documented (mean BNP 775 ± 926 pg/ml). Following the high BNP, a measure of LVEF was obtained (including outside studies documented by the primary care provider) within 6 months in only 53% (113 of 212) of those with an LVEF not known to be low. Of those with a follow-up echocardiogram, the LVEF was <40% in 18/113 (16%) and >=40% in 95/113 (84%). There was no significant difference in mean initial BNP values between those with a follow-up LVEF <40% (872 ± 940pg/ml), >=40% (704 ± 737 pg/ml), or not done (661 ± 649 pg/ml, p=0.5). Conclusions: Follow-up measures of LVEF did not occur in almost 50% of patients with a high BNP where the information may have led to institution of life-prolonging therapy. Of those that did have a follow-up study a new diagnosis of depressesd LVEF was noted in 16%. Screening of existing BNP and LVEF data and may be an efficient strategy to identify patients that may benefit from life-prolonging therapy for heart failure.

Independent Risk Factors

Dilated cardiomyopathy (DCM) is the most common form of cardiomyopathy and cause of cardiac transplantation in children and young adults; mortality is high among this patient population. However, mortality, clinical course, and illustrative echocardiographic data of DCM in children and adults are not well established. Our objective was to provide a research article of detailed descriptions of the incidence, causes, outcomes, related risk factors, and new echocardiographic criteria of risk of death from DCM. Our results showed that independent risk factors at DCM diagnosis for subsequent death or transplantation in children cohorts were older age, congestive heart failure, lower left ventricular ejection fraction (EF ≤ 25%), low global strain, significant mitral valve incompetence, pulmonary hypertension, diastolic dysfunction, right ventricular involvement, and cause of DCM (p< 0.001 for all). In adults, low ejection fraction (<30–35%), global peak systolic strain <-7.6%, increased EDV, ESV, LBBB, diastolic dysfunction, and left ventricle dyssynchrony were the main independent risk factors for major cardiac events and need for CRT or transplantation (p< 0.001 for all). Our conclusions were that in children and adults, DCM is a diverse disorder with outcomes that depend largely on cause, age, heart failure status at presentation, and echocardiographic parameters of the heart (systolic and diastolic function of left ventricle, pulmonary artery pressure, global strain, and valvular function of the mitral valve). This study will present new findings in the diagnostic area.

Abstract Purposes We examined how changes in left ventricular (LV) global longitudinal strain (GLS) were associated with prognosis in patients with preserved LV ejection fraction (LVEF) after congestive heart failure (HF) admission. Methods We studied 123 consecutive patients (age 70 ± 15 years, 55% male) who had been hospitalized due to congestive HF with preserved LVEF (&gt; 50%). The exclusion criteria were atrial fibrillation and inadequate echo image quality for strain analyses. The patients underwent speckle-tracking echocardiography and measurement of plasma NT-ProBNP levels on the same day at the time of hospital admission as well as in the stable condition after discharge. Differences in GLS, LVEF and NT-ProBNP (delta GLS, LVEF and NT-ProBNP ; 2nd – 1st measurements) were calculated. The study end points were all-cause mortality and cardiac events. Results Mean periods of echo performance after hospitalization were 2 ±１days (1st echo) and 240 ± 289 days (2nd echo), respectively. During the follow-up (974 ± 626 days), 12 patients died and 25 patients were hospitalized because of HF worsening. In multivariate analysis, delta GLS and follow-up GLS were prognostic factors, whereas baseline and follow-up LVEF, NT-ProBNP, changes in LVEF and NT-ProBNP could not predict cardiac events. Delta GLS (p = 0.002) turned out to be the best independent prognosticator. Receiver operating characteristics analysis revealed that -0.6% of delta GLS was the optimal cut-off value to predict cardiac events and mortality (sensitivity 76%, specificity 67%, AUC 0.75). Kaplan-Meier analysis showed that patients with delta GLS more than -0.6% experienced significantly less cardiac events during the follow-up period (p &lt; 0.0001, log-rank). Conclusion A change in LV GLS after congestive HF admission was a predictor of the prognosis in patients with preserved LVEF. It would be useful to check the changes in GLS in those with preserved LVEF after discharge.

Copper Deficiency (CuD) leads to hypertrophic cardiomyopathy in various experimental models. The morphological, electrophysiological, and molecular aspects of this hypertrophy have been under investigation for a long time. However the transition from compensated hypertrophy to decompensated heart failure has not been investigated in the study of CuD. We set out to investigate the contractile and hemodynamic parameters of the CuD mouse heart and to determine whether heart failure follows hypertrophy in the CuD heart. Dams of FVB mice were fed CuD or copper-adequate (CuA) diet starting from the third day post delivery and the weanling pups were fed the same diet for a total period of 5 weeks (pre- and postweanling). At week 4, the functional parameters of the heart were analyzed using a surgical technique for catheterizing the left ventricle. A significant decrease in left ventricle systolic pressure was observed with no significant change in heart rate, and more importantly contractility as measured by the maximal rate of left ventricular pressure rise (+dP/dt) and decline (−dP/dt) were significantly depressed in the CuD mice. However, left ventricle end diastolic pressure was elevated, and relaxation was impaired in the CuD animals; the duration of relaxation was prolonged. In addition to significant changes in the basal level of cardiac function, CuD hearts had a blunted response to the stimulation of the β-adrenergic agonist isoproterenol. Furthermore, morphological analysis revealed increased collagen accumulation in the CuD hearts along with lipid deposition. This study shows that CuD leads to systolic and diastolic dysfunction in association with histopathological changes, which are indices commonly used to diagnose congestive heart failure.
