Introduction: Increased left atrial (LA) size and reduced LA function are known predictors of atrial fibrillation (AF). Evidence also links increased LA size and stroke. We sought to examine the association of LA function, measured with cardiac magnetic resonance imaging (CMR) and incident stroke/TIA and dementia. Methods: This case-cohort study compared LA size and function in 180 MESA participants with incident Stroke/TIA and 95 with incident dementia, over a median follow up of 10.7 years, to 550 participants randomly selected from the whole MESA cohort. All individuals were free of clinical cardiovascular and major valvular heart disease. Phasic LA volumes, LA emptying fractions (LAEF) and peak strain were quantified in sinus rhythm using tissue-tracking CMR. Vascular neurologists adjudicated stroke events by medical record review. Dementia cases were identified using ICD9 codes from hospital records. Modified Cox proportional hazard models weighted for the stratified case-cohort sampling design was used to examine the associations. Results: Incident Stroke/TIA (age 67 ± 9 years, 45% male) and dementia cases (age 74 ± 6 years, 58% male) were older than the subcohort population (age: 61 ± 10, 49% male). In multivariable analysis adjusted for standard cardiovascular risk factors and left ventricular ejection fraction, lower peak LA strain and passive LAEF were associated with both incident stroke/TIA and dementia. After further adjustment for incident AF, the associations were attenuated for peak LA strain but remained significant for passive LAEF (HR for incident Stroke/TIA: 0.72 per SD 95% CI: 0.55-0.93, p=0.013 and for incident dementia: 0.59 per SD 95% CI: 0.37-0.95, p=0.031). Conclusions: Reduced LA conduit function was associated with incident Stroke/TIA and dementia independent of other cardiovascular risk factors and incident AF. Assessment of LA function may add further information in risk stratifying individuals at risk for stroke and dementia.

Background: Cardiovascular disease is the major cause of death in dialysis patients, as well as in kidney transplant patients. Assessment of cardiovascular risks of renal transplant candidates to prevent or slow the progression of cardiovascular abệnh nhânormalities. Aim: 1) Evaluating cardiovascular risk factors, electrocardiographic and echocardiographic abnormalities in renal transplant candidates. 2) Identifying the correlation between cardiac morphological parameters with a number of factors involved. Subjects and Methods: We assessed 57 patients (73.7% male, mean age 32.4±8.8) with end-stage renal disease waiting for renal transplantation at Cho Ray Hospital between Jan 2012 and Jan 2013. All patients received a physical examination, blood pressure measurement, Hb, blood glucose test, lipid profile, ECG, echocardiography. Results: The percentage of hypertension was 98.2%, smoking (69.2%), dyslipidemia 40.4% and diabetes 12.3%. All patients had sinus rhythm, left ventricular hypertrophy 61.4% in ECG. Pericardial effusion 5.3%, mitral valve insufficiency 56.1%, aortic valve insufficiency 12.3%, left ventricular hypertrophy 94.7% in echocardiography. IVSd, LVPWd, LVMI positively correlated with kidney failure time (p <0.01, p<0.001), with DBP and SBP (p <0.05) and the degree of anemia (p <0.05). Percentage the degree of hypertension associated with proportion of left ventricular hypertrophy (p <0.05). Conclusions: Identification of cardiovascular risk factors for the prevention or intervention to reduce mortality in renal transplantation. Keywords: Cardiovascular risk factors, end-stage chronic renal failure, renal transplantation.

Abstract Objectives The objective of this study is to investigate the cardiovascular risk factors associated with metabolic syndrome (MetS), which is increasingly becoming prevalent in childhood obesity. Methods A total of 113 patients, 76 of whom were between the ages of 10 and 17 (mean age: 14.5 ± 1.8 years) and diagnosed with obesity (30 non-MetS and 46 MetS using IDF) and 37 of whom constituted the control group, participated in the study. Echocardiographic examination and atherogenicity parameters (Atherogenic index of plasma [AIP: logTG/HDL], total cholesterol/HDL, and TG/HDL ratio and non-HDL) were evaluated. Results The most common component accompanying obese MetS was found to be hypertension and low HDL. While obesity duration, body mass index (BMI), blood pressure, fasting insulin, insulin resistance, atherogenicity parameters were determined to be significantly higher in the obese-MetS group. Echocardiography showed that while the thickness, volume, and diameter of LV end-diastolic wall, left ventricular mass (LVM), LVM index (LVMI g/m2) and relative wall thickness (RWT) were significantly high in the MetS group, however, mitral E/A ratio was significantly lower (p<0.05). Change in LV geometry consistent with concentric remodeling (increased RWT, normal LVMI) was visible in obese groups. LVM were positively significantly related to BMI, waist circumference, insulin resistance, blood pressure, LDL level, and negative to mitral E/A ratio. In the obese-MetS group, LVMI was positively correlated to office systolic BP, left atrium end-diastolic volume/index. Conclusions LVMI and atherogenicity parameters that were found to be significantly higher in obese MetS exhibit increased cardiovascular risk in childhood.

Common Finding

Abstract Aim Left ventricular diastolic dysfunction (DD), a common finding in the general population, is considered to be associated with heart failure with preserved ejection faction (HFpEF). Here we evaluate the prevalence and correlates of DD in subjects with and without HFpEF in a middle-aged sample of the general population. Methods and results From the first 10,000 participants of the population-based Hamburg City Health Study (HCHS), 5913 subjects (mean age 64.4 ± 8.3 years, 51.3% females), qualified for the current analysis. Diastolic dysfunction (DD) was identified in 753 (12.7%) participants. Of those, 11.2% showed DD without HFpEF (ALVDD) while 1.3% suffered from DD with HFpEF (DDwHFpEF). In multivariable regression analysis adjusted for major cardiovascular risk factors, ALVDD was associated with arterial hypertension (OR 2.0, p < 0.001) and HbA1c (OR 1.2, p = 0.007). Associations of both ALVDD and DDwHFpEF were: age (OR 1.7, p < 0.001; OR 2.7, p < 0.001), BMI (OR 1.2, p < 0.001; OR 1.6, p = 0.001), and left ventricular mass index (LVMI). In contrast, female sex (OR 2.5, p = 0.006), atrial fibrillation (OR 2.6, p = 0.024), CAD (OR 7.2, p < 0.001) COPD (OR 3.9, p < 0.001), and QRS duration (OR 1.4, p = 0.005) were strongly associated with DDwHFpEF but not with ALVDD. Conclusion The prevalence of DD in a sample from the first 10,000 participants of the population-based HCHS was 12.7% of whom 1.3% suffered from HFpEF. DD with and without HFpEF showed significant associations with different major cardiovascular risk factors and comorbidities warranting further research for their possible role in the formation of both ALVDD and DDwHFpEF.
