TÓM TẮT Mục tiêu: Khảo sát chức năng tâm trương thất trái theo khuyến cáo ASE/EACVI 2016 ở bệnh nhân bệnh cơ tim giãn bằng siêu âm tim. Tìm hiểu mối liên quan giữa chức năng tâm trương thất trái với tình trạng giãn thất trái, độ suy tim NYHA, phân suất tống máu thất trái, phân suất co cơ thất trái. Đối tượng và phương pháp nghiên cứu: Nghiên cứu mô tả cắt ngang trên 56 bệnh nhân bệnh cơ tim giãn nguyên phát được nhập viện và điều trị tại bệnh viện Trung ương Huế từ tháng 4/2018 đến tháng 8/2020. Kết quả: Đường kính thất trái cuối tâm trương và cuối tâm thu trung bình là 66,11 ± 7,3 mm và 57,7 ± 8,02 mm. Đường kính nhĩ trái trung bình là 40,61 ± 7,65 mm. Phân suất tống máu thất trái trung bình là 24,68 ± 5,97 %. Phân suất co cơ thất trái trung bình là 12,91 ± 4,55 %. Tất cả các bệnh nhân nhóm nghiên cứu đều có rối loạn chức năng tâm trương thất trái. Chiếm tỷ lệ cao nhất là rối loạn chức năng tâm trương độ II (44,6%), tiếp sau là rối loạn chức năng tâm trương độ III (35,8%) và rối loạn chức năng tâm trương độ I là 19,6%. Không có sự liên quan có ý nghĩa thống kê giữa mức độ rối loạn tâm trương thất trái với đường kính thất trái cuối thì tâm thu và tâm trương (p > 0,05). Có mối liên quan giữa rối loạn chức năng tâm trương thất trái với các thông số phân suất tống máu EF và phân suất co cơ FS (p < 0,005). Có sự tương quan thuận mức độ vừa giữa phân độ rối loạn chức năng tâm trương thất trái với phân độ suy tim theo NYHA với r = 0,445, sự tương quan đó có ý nghĩa thống kê (p < 0,001). Kết luận: Tất cả các bệnh nhân bệnh cơ tim giãn trong nhóm nghiên cứu đều có rối loạn chức năng tâm trương thất trái, chủ yếu là rối loạn chức năng tâm trương nặng độ II - III. Sự rối loạn này thể hiện rõ qua sự biến đổi các thông số đánh giá chức năng tâm trương thất trái trên siêu âm tim theo khuyến cáo ASE/ EACVI 2016, một khuyến cáo mới đưa ra nhằm tiếp cận đánh giá chức năng tâm trương một cách thuận tiện và dễ dàng hơn. Từ khóa: Bệnh cơ tim giãn, rối loạn chức năng tâm trương thất trái, khuyến cáo ASE/EACVI 2016 ABSTRACT EVALUATION OF LEFT DYSTOLIC FUNCTION ACCORDING TO THE RECOMMENDATION ASE/EACVI 2016 INPATIENTS WITH DILATED CARDIOMYPAHTIES Background: Dilated cardiomyopathy is a disease of the heart muscle, characterized by dilatation of the heart chamber and a dysfunction of the left or both ventricles. It often leads to progressive heart failure, and is the leading cause of heart transplant among all cardiomyopathy. The annual rate of sudden cardiac death in dilated cardiomyopathy is 2 - 4%, with sudden death accounting for half of all deaths [9]. Echocardiography is an evaluation of a patient with dilated cardiomyopathy. There have been many studies on dilated cardiomyopathy in the world. However, there are still few studies evaluating diastolic function in patients with dilated cardiomyopathy using cardiac Doppler echocardiography. Experts around the world have made many recommendations in assessing left ventricular diastolic function, most recently is the recommendation ASE/EACVI 2016. Comparing with the 2009 EAE/ASE recommendation, the recommendation ASE/EACVI 2016 for assessment of left ventricular diastolic function has fewer parameters, so it is easier to implement and more convenient in clinical practice. Objective: Surveying left ventricular diastolic function according to the recommendation ASE/EACVI 2016 in patients with dilated cardiomyopathy by echocardiography and investigating the relationship between left ventricular diastolic function with left ventricular dilatation, heart failure NYHA, left ventricular ejection fraction, left ventricle fractional shortening. Methods: Research was designed as a cross - sectional descriptive study. Studied on 56 patients with primary dilated cardiomyopathy were hospitalized and treated at Hue Central Hospital. Results: The results showed: The mean end - diastolic and end - systolic left ventricular diameters were 66,11 ± 7,3 mm and 57,7 ± 8,02 mm. The mean left atrial diameter was 40,61 ± 7,65 mm. The mean left ventricular ejection fraction was 24,68 ± 5,97%. The mean fractional shortening of left ventricular contraction was 12,91 ± 4,55%. All patients in the study group had left ventricular diastolic dysfunction. The highest proportion is diastolic dysfunction grade II (44,6%), followed by diastolic dysfunction grade III (35,8%) and diastolic dysfunction grade I is 19,6%. There was no statistically significant relationship between the classification of left ventricular diastolic dysfunction and left ventricular systolic and diastolic diameter (p > 0.05). There is a relationship between left ventricular diastolic dysfunction and parameters of ejection fraction EF and contraction fraction FS (p < 0.005). There is a moderate positive correlation between the classification of left ventricular diastolic dysfunction and the heart failure rating according to NYHA (r = 0,445, p < 0,001). Conclusion: All patients in the study group had left ventricular diastolic dysfunction, mostly grade II and grade III diastolic dysfunction. This disorder is clearly demonstrated by the change in the parameters of the left ventricular diastolic function assessment on echocardiography according to the 2016 ASE/ EACVI recommendations, a new recommendation introduced to approach the assessment of diastolic functionmore convenient and easier way. Key words: Dilated cardiomyopathy, left ventricular diastolic dysfunction, the recommendation ASE / EACVI 2016.

Introduction: Endothelial dysfunction plays a central role in the pathogenesis of diabetic vascular disease. Hypothesis: Although resultant left ventricular diastolic dysfunction is hypothesized to reduce exercise capacity, limited data exist on the relation between endothelial function, left ventricular diastolic function and exercise capacity in patients with type 2 diabetes. Methods: We recruited 231 subjects with type 2 diabetes, a preserved ejection fraction, a negative stress test and a sodium-restricted diet. All subjects underwent a brachial artery flow-mediated dilation (FMD) measurement, a transthoracic echocardiography and a standard submaximal Bruce protocol treadmill exercise test during the hospitalization period for diabetes education program. Results: Impaired FMD (%FMD 8) were found in 193 subjects (84%) and 174 subjects (75%), respectively, of which 11 (5%) had diastolic dysfunction (E/E’ >15). Mean E/E’ by quartile (Q) were: Q1 6.9, Q2 8.9, Q3 10.4, and Q4 14.0. E/E’ was inversely correlated with %FMD (2.9 ± 4.3%, r = -0.19, p = 0.003) and exercise duration (460 ± 150 sec, r = -0.30, p <0.001). Compared with subjects in Q4, those in Q1, Q2 and Q3 had longer exercise duration (Q1 500 ± 150 sec, Q2 510 ± 140 sec, Q3 460 ± 140 sec and Q4 390 ± 140 sec, p <0.001). After adjustment for potential confounders including age, gender, smoking, body mass index, medication for hypertension, diabetes duration of more than 5 years, HbA1c and systolic blood pressure, %FMD and exercise duration were significantly associated with E/E’ (β = -0.17 and -0.18, p = 0.006 and 0.014) in all subjects. Conclusions: Diabetes patients with impaired endothelial function have impaired left ventricular diastolic function potentially leading to exercise intolerance.

Abstract Objective: Mounting evidence links cirrhosis patients with left ventricular diastolic dysfunction(LVDD) has a poor prognosis. However, little is known about these particular individuals. Therefore, we conducted this cross-sectional study to assess the prevalence of LVDD and its associated risk factors.Methods: Consecutive cirrhosis patient who were attending Hangzhou Xixi hospital from January 2018 to December 2019 were included in this study. According to the American Society of Echocardiography 2016 criteria, cirrhosis patients were sorted into two group: the left ventricular diastolic dysfunction(LVDD) group and left ventricular diastolic function normal(LVDDn) group. Patients’ demographic data, clinical characteristics, laboratory data were recorded. Furthermore, we conducted a multi-factor analysis.Results: A total of 398cirrhosis patients were included in the study. The incidence of LVDD in this study was 49.7% (198 cases). In this study, the mean age and BMI of the patients were 52.9±8.2 years and 23.0±3.3kg/m2,respectively. Of 398 patients, 255(64.1%) of them were males. With regard to etiology, there were 296 patients (74.4%) with hepatitis B cirrhosis and 59 patients (14.8%) with alcoholic cirrhosis. The LVDD group had higher age, higher BMI, greater frequency of ascites and esophageal varices, prolonged prothrombin time, increased international normalized ratio, increased bilirubin, increased CK and AST, and longer QT interval than the LVDDn group(p<0.05, both). In terms of echocardiography, the LVDD group had larger aortic inner diameter, left atrial inner diameter and left ventricular wall diastolic thickness than LVDDn group(p<0.05, both). The multivariate analysis showed age>55 years, BMI>24kg/m2, hepatic decompensated, QTcB>440ms were independently associated with risk of LVDD.Conclusion: The prevalence of LVDD among cirrhosis patients was 49.8%. Cirrhosis patients with LVDD had worse liver function. Further, age>55 years, BMI>24kg/m2, hepatic decompensated, QTcB>440ms were independent predictors of LVDD.

Introduction: Severe left ventricular diastolic dysfunction is associated with worse prognosis after acute myocardial infarction (MI). Twenty percent of patients have a restrictive filling pattern (RFP) following MI, and this is associated with a fourfold increase in mortality. The determinants of diastolic function in this setting are not well defined. Aim: We sought to determine the correlation between enzymatic infarct size and RFP in patients with a first ever MI. We hypothesized that a larger infarct size would result in greater impairment of left ventricular diastolic function. Methods: Data analysis was performed on consecutive patients admitted with first ever non-ST elevation MI (NSTEMI) or ST-elevation MI (STEMI) to a single large tertiary referral hospital from January 2013 to December 2014. All patients underwent coronary angiography during the index admission. Infarct size was determined by peak troponin I. Doppler transmitral flow pattern was obtained from the initial transthoracic echocardiogram performed within 48 hours of admission. RFP was defined as: E/A ratio >2.0 and/or E-wave deceleration time <160ms (American Society of Echocardiography Guidelines 2009). Results: Data were available on 645 consecutive patients who underwent coronary angiography for MI. We excluded 160 patients with a previous MI. Of the remaining 485 patients (mean age 62±13 years; mean left ventricular ejection fraction (LVEF) 53±12%), there were 338 NSTEMIs (70%) and 147 STEMIs (30%). PCI was performed in 360 (74%) patients (single vessel (82%), ≥2 vessels (18%)); coronary artery bypass surgery in 58 (13%); and medical management in 67 (13%). Sixty-nine patients (14.4%) had RFP; 52% of these had a LVEF ≥45%. Peak troponin I levels were higher in the RFP group (31.8±30.9μg/L vs 16.8±25.2μg/L, p=<0.001). On multivariate analysis, infarct size by peak troponin I (OR 1.02, 95%CI 1.00-1.03, p=0.026) and low LVEF (OR 0.95, 95%CI 0.91-0.99, p=0.015) were the only independent predictors of RFP. Conclusion: Infarct size was a major determinant of diastolic dysfunction following first ever MI. Whilst LV systolic dysfunction was strongly associated with impaired diastolic function, 52% of patients with severe diastolic dysfunction had relatively preserved LVEF.

Background In the past, cardiovascular involvement did not seem to be a common complication of HIV, but in recent years it has been described more frequently. With the advent of highly active antiretroviral therapy (HAART), the symptoms of cardiac disease has changed, as the number of HIV-infected patients with abnormal diastolic parameters has increased significantly, often presenting as symptomatic rather than asymptomatic. Objective To analyze for a possible correlation between HAART duration and left ventricular diastolic function in HIV-infected children. Methods This cross-sectional study was conducted from December 2016 to December 2017 at the Cardiology and Allergy-Immunology Division/Department of Child Health, Universitas Udayana Medical School/Sanglah Hospital, Denpasar, Bali. Subjects with HAART were collected using a consecutive sampling method. The following data were recorded for each subject: age, sex, current stage of HIV, CD4+ level, as well as HAART regimen and duration of use. Transthoracic echocardiography was performed for tissue doppler imaging (TDI) of diastolic function. Spearman’s test was used to analyze the strength of correlation based on normality test results. Results This study involved 53 subjects, 21 of whom had impaired diastolic function. There was no correlation between HAART duration and diastolic function in children with HIV infection (r= -0.03; P=0.82). Conclusion Diastolic dysfunction is found in children under HAART treatment, but there is no correlation between HAART treatment duration and diastolic dysfunction.
