Abstract Background Few prospective studies have evaluated sex-specific pattern, natural progression of left ventricular (LV) remodeling and diastolic dysfunction in patients with type 2 diabetes (T2DM). Purpose The aim of this study was to study the sex-specific prevalence, longitudinal changes of LV remodeling and diastolic dysfunction in patients with T2DM. Further the prognostic value of diastolic function in women and men was also evaluated. Methods A total of 386 patients with T2DM (mean age 61±11 years; women, 48.2%) was recruited. Detailed echocardiography was performed and LV geometry, systolic and diastolic function were measured at baseline and follow-up. A major adverse cardiovascular event (MACE) was defined as cardiovascular death, heart failure hospitalization or myocardial infarction. Multivariable cox-regression adjusted for age, hypertension, LVEF and HbA1c was used to assess the association between sex-specific diastolic function and the development of a MACE. Results Despite a similar age, prevalence of hypertension and body mass index, women had a higher prevalence of LV hypertrophy and diastolic dysfunction at baseline and follow-up compared with men. A total of 26 patients developed a MACE (4 cardiovascular death, 14 hospitalization for heart failure, 8 myocardial infarction) during follow-up. Women with diastolic dysfunction had a higher incidence of MACE than those with normal diastolic function but this association was neutral in men. Multivariable Cox-regression analysis indicated that diastolic dysfunction was associated with MACE in women (hazard ratio 6.35, 95% confidence interval 1.18–34.19, P<0.05) but not men (hazard ratio 1.85, 95% confidence interval 0.58–5.92, P=0.30). Conclusions LV hypertrophy and diastolic dysfunction, both at baseline and follow-up, were more common in women than men. Pre-clinical diastolic dysfunction was independently associated with MACE only in women with T2DM but was neutral in men.

Abstract Aims  Few prospective studies have evaluated sex-specific pattern, natural progression of left ventricular (LV) remodelling, and diastolic dysfunction in patients with type 2 diabetes (T2DM). The aim of this study was to study the sex-specific prevalence, longitudinal changes of LV remodelling, and diastolic dysfunction in patients with T2DM. Further, the prognostic value of diastolic function in women and men was also evaluated. Methods and results  A total of 350 patients with T2DM (mean age 61 ± 11 years; women, 48.3%) was recruited. Detailed echocardiography was performed at baseline and after 25 months. A major adverse cardiovascular event (MACE) was defined as cardiovascular death, heart failure hospitalization, or myocardial infarction. Despite a similar age, prevalence of hypertension and body mass index, women had a higher prevalence of LV hypertrophy and diastolic dysfunction at baseline and follow-up compared with men. A total of 21 patients developed MACE (5 cardiovascular death, 9 hospitalization for heart failure, and 7 myocardial infarction) during a median follow-up of 56 months. Women with diastolic dysfunction had a higher incidence of MACE than those with normal diastolic function but this association was neutral in men. Multivariable Cox-regression analysis indicated that diastolic dysfunction was associated with MACE in women [hazard ratio = 6.30; 95% confidence interval (CI) = 1.06–37.54; P &lt; 0.05] but not men (hazard ratio = 2.29, 95% CI = 0.67–7.89; P = 0.19). Conclusion  LV hypertrophy and diastolic dysfunction, both at baseline and follow-up, were more common in women than men. Pre-clinical diastolic dysfunction was independently associated with MACE only in women with T2DM but was neutral in men.

Cardiac rehabilitation (CR) improves symptoms and survival in patients with acute myocardial infarction (AMI). We studied the change of diastolic function and its prognostic impact after CR. After reviewing all consecutive AMI patients from January 2012 to October 2015, we analyzed 405 patients (mean, 63.7 ± 11.7 years; 300 males) with baseline and follow-up echocardiographic examinations. We divided them into three groups according to their CR sessions: No-CR group (n = 225), insufficient-CR group (CR < 6 sessions, n = 117) and CR group (CR ≥ 6 sessions, n = 63). We compared echocardiographic parameters of diastolic dysfunction including E/e’ ratio > 14, septal e’ velocity < 7 cm/s, left atrial volume index (LAVI) > 34 mL/m2, and maximal TR velocity > 2.8 m/s. At baseline, there were no significant differences in all echocardiographic parameters among the three groups. At follow-up echocardiographic examination, mitral annular e’ and a’ velocities were higher in the CR group (p = 0.024, and p = 0.009, respectively), and mitral E/e’ ratio was significantly lower (p = 0.009) in the CR group. The total number of echocardiographic parameters of diastolic dysfunction at the baseline echocardiography was similar (1.29 vs. 1.41 vs. 1.52, p = 0.358). However, the CR group showed the lowest number of diastolic parameters at the follow-up echocardiography (1.05 vs. 1.32 vs. 1.50, p = 0.017). There was a significant difference between the No-CR group and CR group (p = 0.021). The presence of CR was a significant determinant of major adverse cardiovascular events in the univariate analysis (HR = 0.606, p = 0.049). However, the significance disappeared in the multivariate analysis (HR = 0.738, p = 0.249). In conclusion, the CR was significantly associated with favorable diastolic function, with the highest mitral e’ and a’ velocity, and the lowest mitral E/e’ ratio and total number of echocardiographic parameters of diastolic dysfunction at the follow-up echocardiographic examinations in AMI patients.

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.

Abstract Background The relationship between adipocyte fatty acid-binding protein (AFABP) and cardiac remodelling has been reported in cross-sectional studies, although with conflicting results. Type 2 diabetes mellitus (T2DM) is associated with left ventricular (LV) hypertrophy and diastolic dysfunction, as well as elevated circulating AFABP levels. Here we investigated prospectively the association between AFABP with the longitudinal changes of cardiac remodelling and diastolic dysfunction in T2DM. Methods Circulating AFABP levels were measured in 176 T2DM patients without cardiovascular diseases (CVD) at baseline. All participants received detailed transthoracic echocardiography both at baseline and after 1 year. Multivariable linear and Cox regression analyses were used to evaluate the associations of circulating AFABP levels with changes in echocardiography parameters and incident major adverse cardiovascular events (MACE), respectively. Results The median duration between baseline and follow-up echocardiography assessments was 28 months. Higher sex-specific AFABP quartiles at baseline were associated with increase in LV mass and worsening of average E/e′ (all P < 0.01). Multivariable linear regression demonstrated that AFABP in the highest quartile was independently associated with both increase in LV mass (β = 0.89, P < 0.01) and worsening of average E/e′ (β = 0.57, P < 0.05). Moreover, multivariable Cox regression analysis showed that elevated baseline circulating AFABP level independently predicted incident MACE (HR 2.65, 95% CI 1.16–6.05, P < 0.05) after adjustments for age, sex, body mass index, glycated haemoglobin, hypertension, dyslipidemia and presence of chronic kidney disease. Conclusion Circulating AFABP level at baseline predicted the development of LV hypertrophy, diastolic dysfunction and MACE in T2DM patients without CVD.

Abstract Aims The described association of low diastolic blood pressure (DBP) with increased cardiovascular outcomes could be due to reduced coronary perfusion or is simply due to reverse causation. If DBP is physiologically relevant, coronary reperfusion after myocardial infarction (MI) might influence DBP–risk association. Methods and results The relation of achieved DBP with cardiovascular death or cardiovascular hospitalization, cardiovascular death, and all-cause death was explored in 5929 patients after acute myocardial infarction (AMI) with impaired left ventricular function, signs and symptoms of heart failure, or diabetes in the EPHESUS trial according to their reperfusion status. Cox regression models were used to assess the impact of reperfusion status on the association of DBP and systolic blood pressure (SBP) with outcomes in an adjusted fashion. In patients without reperfusion, lower DBP &lt;70 mmHg was associated with increased risk for all-cause death [adjusted hazard ratios (HRs) 1.80, 95% confidence interval (CI) 1.41–2.30; P &lt; 0.001], cardiovascular death (HR 1.70, 95% CI 1.3–3.22; P &lt; 0.001), cardiovascular death or cardiovascular hospitalization (HR 1.54, 95% CI 1.26–1.87; P &lt; 0.001). In patients with reperfusion, the risk increase at low DBP was not observed. At low SBP, risk increased independently of reperfusion. A sensitivity analysis in the subgroup of patients with optimal SBP of 120–130 mmHg showed again risk reduction of reperfusion at low DBP. Adding the treatment allocation to eplerenone or placebo into the models had no effects on the results. Conclusion Patients after AMIs with a low DBP had an increased risk, which was sensitive to reperfusion therapy. Low blood pressure after MI identifies in patients with particular higher risk. These data support the hypothesis that low DBP in patients with stenotic coronary lesions is associated with risk, potentially involving coronary perfusion pressure and the recommendations provided by guidelines suggesting lower DBP boundaries for these high-risk patients.

SummaryBackground:Since serial analyses of NT-proBNP in patients with acute coronary syndromes have shown that levels measured during a chronic, later phase are a better predictor of prognosis and indicator of left ventricular function than the levels measured during an acute phase, we sought to assess the association of NT-proBNP, measured 6 months after acute myocardial infarction (AMI), with traditional risk factors, characteristics of in-hospital and early postinfarction course, as well as its prognostic value and optimal cut-points in the ensuing 1-year follow-up.Methods:Fasting venous blood samples were drawn from 100 ambulatory patients and NT-proBNP concentrations in lithium-heparin plasma were determined using a one-step enzyme immunoassay based on the »sandwich« principle on a Dimension RxL clinical chemistry system (DADE Behring-Siemens). Patients were followed-up for the next 1 year, for the occurrence of new cardiac events.Results:Median (IQR) level of NT-proBNP was 521 (335–1095) pg/mL. Highest values were mostly associated with cardiac events during the first 6 months after AMI. Negative association with reperfusion therapy for index infarction confirmed its long-term beneficial effect. In the next one-year follow-up of stable patients, multivariate Cox regression analysis revealed the independent prognostic value of NT-proBNP for new-onset heart failure prediction (p=0.014), as well as for new coronary events prediction (p=0.035). Calculation of the AUCs revealed the optimal NT-proBNP cut-points of 800 pg/mL and 516 pg/mL, respectively.Conclusions:NT-proBNP values 6 months after AMI are mainly associated with the characteristics of early infarction and postinfarction course and can predict new cardiac events in the next one-year follow-up.

Objectives: Patients with hypertrophic obstructive cardiomyopathy (HOCM) and severe left ventricular hypertrophy (maximal left ventricular wall thickness ≥30 mm) are at high risk of sudden cardiac death (SCD). In this study, we aimed to determine whether HOCM patients with severe hypertrophy had a lower incidence of SCD after myectomy. Methods: HOCM patients with severe hypertrophy were consecutively enrolled from Fuwai Hospital in China between 2000 and 2013. Long-term outcomes were retrospectively compared between the 2 groups, namely the myectomy group and medical group. Results: A total of 244 patients (118 in the myectomy group and 126 in the medical group) were involved. The mean follow-up durations for the myectomy and medical groups were 5.07 ± 3.73 and 6.23 ± 4.15 years, respectively. During the follow-up period, the annual cardiovascular mortality rate was 0.84% in the myectomy group and 2.04% in the medical group (p = 0.041). The annual SCD rate was 0.33% in the myectomy group and 1.40% in the medical group (p = 0.040). Multivariate Cox regression analysis showed that myectomy was independently associated with lower rates of cardiovascular death and SCD. Conclusions: In HOCM patients with severe hypertrophy, those that underwent myectomy had a lower risk of cardiovascular death and SCD than those treated with medicines only.

Clinical studies have shown a greater incidence of myocardial infarction in diabetic patients, and following an infarction, diabetes is associated with an increased risk for the development of left ventricular (LV) dysfunction and heart failure. The goal of this study was to determine if the progression of heart failure following myocardial infarction in type 2 diabetic (T2D) rats is accelerated compared with nondiabetic rats. Male nondiabetic Wistar-Kyoto (WKY) and T2D Goto-Kakizaki (GK) rats underwent coronary artery ligation or sham surgery to induce heart failure. Postligation (8 and 20 wk), two-dimensional echocardiography and LV pressure measurements were made. Heart failure progression, as assessed by enhanced LV remodeling and contractile dysfunction, was accelerated 8 wk postligation in the T2D animals. LV remodeling was evident from increased end-diastolic and end-systolic diameters and areas in the GK compared with the WKY infarcted group. Furthermore, enhanced LV contractile dysfunction was evident from a greater deterioration in fractional shortening and enhanced myocardial performance index (an index of global LV dysfunction) in the GK infarcted group. This accelerated progression was accompanied by greater increases in atrial natriuretic factor and skeletal α-actin (gene markers of heart failure and hypertrophy) mRNA levels in GK infarcted hearts. Despite similar decreases in metabolic gene expression (i.e., peroxisome proliferator-activated receptor-α-regulated genes associated with fatty acid oxidation) between infarcted WKY and GK rat hearts, myocardial triglyceride levels were elevated in the GK hearts only. These results, demonstrating enhanced remodeling and LV dysfunction 8 wk postligation provide evidence of an accelerated progression of heart failure in T2D rats.

It is also useful in assessing the benefit of revascularization. Its identification is also of clinical importance in order to set up preventive strategies for patients with adverse remodeling Purpose To find an echocardiographic predictor of LV adverse remodeling following STEMI. Materials and methods In this prospective study we included 52 consecutive patients, aged between 35-70,  with STEMI treated by primary PCI. We performed conventional 2D transthoracic echocardiography for patients. In addition to conventional parameters we also measured LV global longitudinal strain (GLS) and LV mechanical dispersion using 2D speckle tracking imaging. For morphological and functional analysis of LV we used 3D echocardiography (volumes, LVEF). LV remodeling (LVR) was defined as an increase of over 15% of the LV end diastolic volume (LVEDV) at 6 months follow up. Results We found significant differences in time (baseline and 6 month follow up) between LVEF (43,08 vs 47,91, p = 0.034), LVEDV (105,95 vs 113,21, p = 0.000), LV GLS (-12.61 vs - 14,58, p = 0.01), and mechanical dispersion (61,68 vs 56,11, p = 0.00) in all patients. LV remodeling at 6 months (15% increase in LVEDV) was observed in 30 % of the included patients. At 6 months after STEMI we observed a significant difference between the two groups (remodeling vs no remodeling) regarding 3D LVEF (42.28 %vs 50.30%,p = 0.009), LVEDV (131 ml vs 109 ml, p = 0.05), GLS (-11.15 vs -16.02, p = 0.00) and LV mechanical dispersion (69.02 vs 50.54, p = 0.00). Patients with LV remodeling at 6 months after STEMI had lower LVEF, worse LV GLS and higher LV mechanical dispersion at baseline. Using ROC curve analysis we identified two cut off values, one of -11.55 for baseline LV GLS (Sb 78%, Sp 81%, AUC 0.852, CI 95%, p = 0.00) and another one of 63.7 for LV baseline mechanical dispersion (Sb 71,4%, Sp 66 %, AUC 0.762, p 0.005) to discriminate between patients with or without LV adverse remodeling at 6 months. Using linear regression analysis, we demonstrated that GLS (p = 0.00) and LV mechanical dispersion (p = 0.016) are able to predict LV remodeling in time. We also found a negative correlation between peak CK-MB levels at baseline LVEF at 6 months. Regression analysis showed that CK-MB levels at baseline could predict LVEF at 6 months (p = 0.008) Conclusion Baseline LV mechanical dispersion and LV GLS can predict LV adverse remodeling at 6 months after STEMI. These parameters could be used at baseline in order to predict worse outcome in STEMI patients. Further larger scale studies are needed to validate these findings.
