ABSTRACT

Evidence for non-modifiable and modifiable factors associated with the utilization of advance directives (ADs) in heart failure (HF) is lacking. The purpose of this study was to examine baseline-to-3-month changes in knowledge, attitudes, and benefits/barriers regarding ADs and their impact on the completion of life-sustaining treatment (LST) decisions at 3-month follow-up among patients with HF. Prospective, descriptive data on AD knowledge, attitudes, and benefits/barriers and LSTs were obtained at baseline and 3-month follow-up after outpatient visits. Of 64 patients (age, 68.6 years; male, 60.9%; New York Heart Association (NYHA) classes I/II, 70.3%), 53.1% at baseline and 43.8% at 3-month follow-up completed LST decisions. Advanced age (odds ratio (OR) = 0.91, p = 0.012) was associated with less likelihood of the completion of LST decisions at 3-month follow-up, while higher education (OR = 1.19, p = 0.025) and NYHA class III/IV (OR = 4.81, p = 0.049) were associated with more likelihood. In conclusion, advanced age predicted less likelihood of LST decisions at 3 months, while higher education and more functional impairment predicted more likelihood. These results imply that early AD discussion seems feasible in mild symptomatic HF patients with poor knowledge about ADs, considering the non-modifiable and modifiable factors.

ABSTRACT

BACKGROUND AND OBJECTIVES: Empirical evidence is lacking on the cumulative disease burden of obesity and hypertension and its impact on cardiac function and exercise capacity. The purpose of this study was to determine whether the presence of obesity and hypertension together was associated with cardiac dysfunction and exercise capacity. SUBJECTS AND METHODS: Using a retrospective study design, medical records were reviewed for echocardiographic and treadmill exercise stress test data. Subjects were grouped according to four categories: normal control, obese, hypertensive, or obese and hypertensive. RESULTS: Obese, hypertensive persons showed significantly lower Ea and E/A ratio and greater E/Ea ratio, deceleration time, left ventricular (LV) mass, and LV mass index compared to their counter parts (normal control, obese and/or hypertensive) (all p<0.05), after controlling for age and sex. After controlling for age and sex, significant differences in exercise capacity indices were found, with the obese group having shorter exercise time, lower metabolic equivalents, and lower maximal oxygen uptake than the normal control, hypertensive, or both groups (all p<0.05). The hypertensive or obese and hypertensive group had greater maximal blood pressure compared with the normal control group (all p<0.001). Obese and hypertensive persons were approximately three times more likely to have diastolic dysfunction (odd ratio=2.96, p=0.001), when compared to the reference group (normotensive, non-obese, or hypertensive only persons). CONCLUSION: Diastolic dysfunction was associated with obesity and/or hypertension. The cumulative risk of obesity and hypertension and their impact on diastolic dysfunction which could be modifiable could reduce exercise capacity.

ABSTRACT

OBJECTIVES: The question of whether diabetes mellitus (DM) duration correlates with the severity of dysfunction has not been well studied. We hypothesised that the longer the duration of DM the worse the severity of left ventricular (LV) diastolic dysfunction and increased risk of cardiovascular disease (CVD). METHODS: We reviewed 547 diabetic patients between January 2005 and April 2010. Finally, 92 consecutive patients who presented with type 2 DM and who underwent echocardiographic assessment were enrolled according to the selection criteria. In all patients, ischaemic heart disease and heart failure were excluded. RESULTS: Diastolic parameters were significantly worsened with increasing duration of DM (p<0.05). In the ≥7 years DM duration group (n=50), the E/Ea ratio increased significantly and the Ea/Aa ratio decreased significantly, compared with those in the <7 years DM duration group (n=42). CVD developed in 28 patients (30.4%) during the follow-up period. However, the duration of DM showed less statistical correlation with the incidence of CVD (p=0.188) and other LV diastolic function indices did not differ significantly between groups with or without CVD. CONCLUSIONS: Alteration of diastolic function induced by DM worsens with increasing duration of DM. DM duration on echocardiographic evaluation time did not differ significantly between the CVD incident and the non-CVD incident groups. The rate of CVD development was not significantly different if the duration of DM was more than 7 years. Therefore, active medical care including echocardiography should be undertaken to prevent CVD from the point of diagnosis of type 2 DM.

ABSTRACT

Portopulmonary hypertension is a complication of chronic liver disease, which has significant effects on survival and prognosis. Although the pathogenesis of pulmonary arterial hypertension has been well known, portopulmonary hypertension is often underestimated in patients with chronic liver disease. Every clinician who manages patients with chronic liver disease complaining of dyspnea should consider portopulmonary hypertension because this disorder requires special treatment. Herein, a 40-year-old woman with liver cirrhosis who complained of dyspnea on exercise is presented. She was diagnosed with portopulmonary hypertension by echocardiography and right-heart catheterization. Beraprost was used to reduce the pulmonary arterial pressure and improve the symptoms. Her symptoms were improved after 2 weeks, and improved symptoms and reduced pulmonary arterial pressure were sustained for 18 months.

ABSTRACT

BACKGROUND AND OBJECTIVES: The purpose of the current study was to assess left atrial (LA) physiology in relation to associations between LA volume change and regional tissue velocities and strains, and to extend this information to patients with mitral stenosis (MS) or mitral regurgitation (MR). SUBJECTS AND METHODS: Twenty-two healthy persons, 22 patients with moderate-to-severe MS, and 22 patients with moderate-to-severe MR were studied. Tissue velocities, strains, and time-volume curves of the LA were acquired using tissue Doppler imaging and 3-dimensional echocardiography. RESULTS: In healthy controls, the maximal LA volume was negatively correlated with the posterior wall longitudinal systolic strain (r=-0.45, p=0.03). The time-to-maximal LA volume was positively correlated with the time-to-posterior wall longitudinal peak strain (r=0.46, p=0.03) and the time-to-circumferential peak strain (r=0.59, p=0.004). The LA active emptying fraction (LAactEF) was positively correlated with the posterior wall longitudinal peak systolic and late diastolic tissue velocities. In patients with MS, the maximal LA volume was negatively correlated with the posterior wall radial peak systolic velocity and the longitudinal late diastolic velocity. In patients with MS, the LAactEF had an additional positive correlation with the anterior wall longitudinal and circumferential systolic velocities, whereas the patients with MR had an additional positive correlation between the LAactEF and the lateral wall longitudinal peak strain as compared with the healthy cantrols. CONCLUSION: LA longitudinal and circumferential deformations are more related than radial deformation to determining LA volume and function. The LA of patients with MS revealed a greater pathologic physiology than those of patients with MR.
