Blood pressure response to head-up tilt (HUT) in 7 healthy subjects and 9 patients before and after coronary artery bypass grafting (CABG) was measured during supine and 15-min 60° HUT. Stroke volume (SV) and ejection fraction (EF) were assessed by echocardiography. Baseline mean arterial pressure (MAP) and heart rate (HR) in patients before CABG were similar to healthy subjects. MAP in patients decreased by 6 (4-9) mmHg [median (1st-3rd quartiles)] during 7-12 mmHg of HUT with decreased cardiac output (CO = SV × HR) while HR remained unchanged. MAP in healthy subjects remained unchanged during HUT with increased HR. Body weight decreased by 3.5 (2.5-3.7) kg and MAP decreased by 6 (2-13) mmHg during the last 3-min HUT while HR increased after CABG. Decreases in SV and CO during HUT disappeared after CABG. Blood pressure decreased during HUT in patients before and after CABG regardless of HR response.

E ect of overweight and obesity on the le ventricular systolic and diastolic functions in patients with acute myocardial infarction AbstractPurpose: e purpose of this study was to evaluate whether a association exits among overweight and obesity and le ventricular systolic and diastolic functions in patients admitted with rst ST-elevation myocardial infarction (STEMI).Methods: e present study was performed on 451 consecutive patients diagnosed with rst STEMI (376 men, 75 women; mean age 56.1±10.8 years). e patients were classi ed into three groups based on their body mass index (BMI) as normal weight (BMI < 25 kg/ m2), overweight (BMI: 25-29.9 kg/m2) and obese (BMI>30 kg/m2). Echocardiographic features were evaluated and compared among the three groups.Results: Mitral annulus E velocities were higher in obese individuals than normal weight group (p <0.01). In contrast, mitral A velocities were lower (p =0.03); consequently, E\A and E'\A' ratios were lower (both p =0.01) in the obese group with respect to normal weight group. When the correction of entire variations existing among the groups were performed using multivariate linear regressions analyses, it turned out that BMI was independently associated with E/A (β= -0.19, p =0.044) and with E'/A' (β= -0.016, p=0.021). Ejection fraction, wall motion score index and myocardial S velocities were comparable among the study groups (p >0.05).Conclusion: ese results suggest that while obesity has no adverse e ect on the le ventricular systolic function, it has unfavorable consequences on the le ventricular diastolic function in the patients with rst STEMI. In contrast, no unfavorable e ects of overweight on the le ventricular systolic and diastolic function were detected.

“…28 Newer TD imaging modalities, such as the assessment of regional annular time intervals, were not considered in this study. 29 Although plasma natriuretic peptide levels have shown to parallel the progression from asymptomatic LV dysfunction to overt HF, a number of precipitating factors, such as cardiac arrhythmias, acute coronary syndromes, and several co-morbidities, may prompt the onset of acute HF in patients with a previously normal or near normal plasma peptide concentration. In addition, factors not directly related to the progression to HF, including age, gender, 30 and concomitant illness, such as advanced renal Figure 3 Event-free survival of stable heart failure patients categorized by tertiles of the ratio of mitral to myocardial early diastolic velocities (E/E m ratio) and further divided according to the median value of plasma N-terminal pro-type B natriuretic peptide.…”

AimsThis study was designed to ascertain whether the combination of Doppler assessment of the ratio of mitral blood flow to myocardial early diastolic velocities (E/E m ratio) and plasma N-terminal pro-type B natriuretic peptide (NT-proBNP) testing is useful to better stratify patients with stable systolic heart failure (HF). Methods and resultsA total of 362 outpatients with chronic systolic HF (left ventricular ejection fraction 45%) underwent clinical assessment, NT-proBNP testing, and comprehensive echo-Doppler study. The endpoint was all-cause mortality or HFrelated hospital admissions (i.e. hospitalization for worsening HF, biventricular pacemaker implantation, or mitral valve surgery). Median follow-up duration was 25 months. Two hundred and fifty-nine patients were judged clinically stable by a Framingham's criteria-based HF score. In multivariate Cox's proportional hazards analysis, plasma NTproBNP (P , 0.0001) and E/E m ratio (P ¼ 0.04) were among the significant predictors of the combined endpoint. Survival free from cardiac mortality and HF-related hospitalization was 55% in patients with the E/E m ratio in the higher third (12), 77% in those with the E/E m ratio in the intermediate third, and 86% in those with the E/E m ratio in the lower third (7) (P , 0.0001). By stratifying patients according to NT-proBNP above the median, patients' outcome was predicted in 13 out of 17 in the intermediate third (P ¼ 0.002) and in 9 out of 10 in the lower third of E/E m ratio (P ¼ 0.005). ConclusionIn patients with stable HF categorized according to the E/E m ratio, NT-proBNP testing improves risk stratification, particularly in those with minor degrees of diastolic dysfunction.--
