- Background: Primary hyperparathyroidism (PHPT) is associated with cardiac disease and increased risk of all-cause and cardiovascular mortality. We investigated cardiac structural and functional parameters before and after successful parathyroidectomy in asymptomatic PHPT patients. Methods and Results: Forty-nine PHPT patients (age: 62.9 +/- 11 years, 5 men) and 48 healthy control subjects, matched for age, sex and smoking status were enrolled in the study. PHPT patients were examined preoperatively and 6 and 12 months postoperatively. Structural and functional cardiac parameters were assessed by transthoracic echocardiography. One year after parathyroidectomy left ventricular (LV) mass, left atrial size, LV enddiastolic and endsystolic diameters, LV posterior wall and interventricular septum diameter, and right ventricular enddiastolic diameter were all increased in PHPT patients, although not significantly. As an indication of worsened LV diastolic function, the heart rate adjusted Doppler-derived deceleration time of the transmittal E-wave increased among PHPT patients (276 +/- 82-303 +/- 54 milliseconds, P = 0.004). There was also deterioration of LV ejection fraction (from 62.7 +/- 7 to 59.9 +/- 7.8%, P = 0.868) and mean atrioventricular plane displacement (from 13.2 +/- 2 to 12.6 +/- 2 mm, P = 0.029). Conclusion: There were no significant differences in heart function between hyperparathyroid and control subjects, and 6 months after parathyroidectomy, there was no change in heart function in hyperparathyroid subjects.

- Primary hyperparathyroidism (pHPT) is associated with cardiac disease. This prospective study was designed to investigate changes in cardiac function before and after parathyroidectomy. Resting and post exercise cardiac function was compared with matched control subjects. Fifty patients (mean age 62.9 +/- 11 years, 45 women) and 50 healthy control subjects, matched for age and sex were studied. Resting and postmaximum exercise echocardiography/Doppler examination were performed at baseline and 6 months after parathyroidectomy. pHPT patients were tested at baseline and 6 months postoperatively. Control subjects were tested only at baseline. Patients were divided into 4 subgroups based on median preoperative levels of PTH and calcium (Ca): high (up arrow) PTI4/ up arrow Ca, up arrow PTH/low (down arrow) Ca, up arrow Ca/ down arrow PTH, and down arrow PTH/ down arrow Ca. No significant difference between pHPT patients and control subjects regarding post exercise systolic function were detected, There was a tendency of lowed E/A among pHPT patients which was significant in subgroup down arrow PTH/ down arrow Ca (1.07 +/- 0.3). Subgroup up arrow PTH/ up arrow Ca showed a lower S/D compared with control subjects at baseline (1.28 +/- 0.3 vs. 1.48 +/- 0.3, P = 0.029). No significant changes regarding post exercise echocardiographic parameters reflecting cardiac function were detected 6 months after parathyriodectomy. Patients with asymptomatic pHPT showed a tendency of elevated filling pressures and signs of impaired diastolic function during exercise.

- Aim: This study aims to investigate cardiac structure and function in patients with asymptomatic primary hyperparathyroidism (pHPT) and if there is any relation to severity regarding serum levels of calcium (Ca) and parathyroid hormone. Methods and Results: We consecutively included 50 patients (mean age 62.9 +/- 11 years, 45 women) with clinically diagnosed pHPT. We prospectively recruited 50 healthy control subjects, matched for age and sex. Standard transthoracic echocardiographic examination was performed using the 4 standard views and structural parameters as well as left ventricular (LV) systolic and diastolic function was determined. Mean LV ejection fraction and atrioventricular plane displacement were on average normal and did not differ between patients and controls. However, pHPT patients had significantly greater LV mass (148 +/- 37 vs. 127 +/- 29 g, P = 0.002), LV end diastolic area (81 +/- 20 vs. 68 +/- 18 cm(2), p = 0.003), LV posterior wall diameter (8.9 +/- 1 vs. 8.1 +/- 1 min, P = 0.006), and LA size (21 +/- 3 vs. 19 +/- 2 mm, P < 0.001). A moderate to severe LV diastolic filling impairment was present in substantially more pHPT patients, compared with control subjects (36% vs. 4%, P < 0:001). Conclusion: Patients with asymptomatic pHPT showed LV structural changes and impaired LV diastolic function.

- Background There is growing evidence that erectile dysfunction is a sentinel for future coronary artery disease. Recently published studies have shown signs of impaired coronary endothelial function in patients with erectile dysfunction, without clinical cardiovascular disease and diabetes. We evaluated the magnitude of coronary vasodilatory dysfunction in men with erectile dysfunction, as compared with men with impaired glucose metabolism (impaired fasting glucose or diabetes) and healthy controls. Methods We investigated men aged 68-73 years with erectile dysfunction (n=12), age-matched men with impaired glucose metabolism, who all proved to have erectile dysfunction (n=15), and age-matched male controls (n=12). Erectile dysfunction was evaluated using the International Index of Erectile Function (IIEF)-5 questionnaire. Coronary flow velocity reserve in the left anterior descending artery was examined using Doppler ultrasound and intravenous adenosine provocation. Results Coronary flow velocities at rest did not differ between the three groups, but maximum coronary flow velocity was significantly lower in the erectile dysfunction group (P= 0.004) and in the impaired glucose metabolism group (P= 0.019), as compared with controls. There was no difference between the erectile dysfunction and impaired glucose metabolism groups. Coronary flow velocity reserve was reduced in the erectile dysfunction group (P=0.026) compared to controls, but was similar compared to the impaired glucose metabolism group. In multivariate analysis including all groups, erectile dysfunction score was the only independent predictor of reduced coronary flow velocity reserve (P=0.020). Conclusions The magnitude of early coronary endothelial and smooth muscle cell dysfunction in otherwise healthy men with erectile dysfunction was comparable to that of patients with impaired glucose metabolism: a well known risk factor for coronary artery disease.

- Abstract in UndeterminedAims: To examine how left atrioventricular plane displacement ( AVPD), a widely used measure of left ventricular (LV) function, is related to presence and degree of aortic stenosis. Methods and results: Cardiac dimensions, LV filling, left AVPD, LV ejection fraction (LVEF), and valve function were assessed by echocardiography/Doppler in 182 patients with various cardiac diseases (mean (SD) age 69 (12) years, 36% women), 49 consecutive with and 133 consecutive without aortic stenosis. In an analysis of covariance, neither left AVPD nor LVEF was independently correlated with the presence of aortic stenosis. However, looking separately at patients with aortic stenosis, left AVPD (p = 0.03) but not LVEF correlated independently with degree of aortic stenosis in multiple linear regression analysis. In patients with aortic stenosis, an abnormal left AVPD had 94% sensitivity and 90% negative predictive value with regard to severe aortic stenosis, compared with 56% and 62%, respectively, for LVEF. Conclusion: In patients with cardiac disease, neither left AVPD nor LVEF correlated independently with presence of aortic stenosis. However, in patients with aortic stenosis, left AVPD but not LVEF correlated with the degree of aortic valve obstruction and left AVPD but not LVEF had high sensitivity and negative predictive value with regard to severe aortic stenosis. Compared with LVEF, left AVPD is an earlier and more sensitive marker of LV haemodynamic load in patients with aortic stenosis.

- Objectives and design. There are conflicting data on gender differences in survival among heart failure (HF) patients. We prospectively assessed gender differences in survival among 930 consecutive patients (464 [49.9%] women, mean age 76.1 +/- 10.1 years), admitted to hospital with suspected or diagnosed HF. Results. Overall, women had lower unadjusted mortality hazard ratio (HR) than men: HR 0.827; 95% confidence interval (CI) 0.690-0.992; p = 0.040. Adjusted HR was 0.786; 95% CI 0.601-1.028; p = 0.079. Unadjusted mortality was significantly higher among patients with a discharge HF diagnosis, compared to those without: HR 1.330; 95% CI 1.107-1.597; p = 0.002; adjusted p = 0.289. Women and men with a discharge HF diagnosis had similar survival: unadjusted HR 1.052; 95% CI 0.829-1.336; p = 0.674; adjusted HR 0.875; 95% CI 0.625-1.225; p = 0.437. Women had lower mortality risk among patients without a discharge HF diagnosis: HR 0.630, 95% CI 0.476-0.833, p = 0.001; adjusted HR 0.611, p = 0.036. Conclusion. Prognosis was poor among patients hospitalised with suspected or diagnosed HF. Among all patients, women had better survival, whereas both sexes had similar survival when the HF diagnosis was certified.

- Background: The increased risk of cardiovascular disease (CVD) in diabetic compared to non-diabetic subjects seems to decrease with age. Whether this age-related reduction applies to CVD risk factors, and whether it is limited to established diabetes mellitus (DM) or also applies to pre-diabetic conditions are not well known. Methods: Using a cross-sectional design we compared the strength of the correlation between glucometabolic disturbances (by grouping), CVD risk factor burden and self-rated health, in two age groups: middle-aged (57-69 years) and older (70-86 years) subjects, (63% men), participating in the Malmo Preventive Project Re-examination Study (n = 18,238). Simple (unadjusted) logistic regression analysis was applied to estimate between-group differences and trends. Interaction analysis was applied to estimate differences between age groups. Results: CVD risk factor burden and the proportion of subjects reporting poor self-rated health increased with increasing glucometabolic disturbance for men and women in both age groups (p-trend < 0.0001 for all). The slope of the trend curve with increasing CVD risk factor burden was significantly steeper for older women than for older men (p-interaction = 0.002). The slope of the trend curve for poor self-rated health was significantly steeper for middle-aged than for older men (p-interaction = 0.005), while no difference was observed between the age groups among women (p-interaction = 0.97). Conclusions: We found no reduction in risk factor accumulation with increasing glucometabolic disturbance between middle-aged and older subjects. Our results indicate life-long CVD risk factor clustering with increased glucometabolic disturbance, and suggest that previously observed age-related reduction in excess CVD risk for subjects with DM might be due to a survival bias. However, our observations indicate more pronounced risk factor clustering and worse self-rated health with increased glucometabolic disturbance in older women than in older men.

- Aim. To describe the self-reported fluid intake and its effects on body weight, signs and symptoms of heart failure, quality of life, physical capacity and thirst, in patients with stabilised chronic heart failure. Background. Patients with chronic heart failure are often recommended a fluid restriction of 1.5 l/day but there is no evidence in the literature for this recommendation and little is known about the fluid intake consequences. Design. Crossover study. Methods. Chronic heart failure patients, clinically stabilised after an unstable state, were randomised to a 32-week cross-over study assessing the clinical importance of fluid prescription. In a secondary analysis of 63 patients, efficacy variables were analysed in relation to the self-reported median fluid intake of 19 ml/kg body weight/day. Results. The mean fluid intake was 16 ml/kg/day in the below-median group and 24 ml/kg/day in the above-median group. No between-group differences were found in change in body weight, signs and symptoms, diuretic use, quality of life or physical capacity. However, the above-median group significantly decreased sense of thirst and difficulties to adhere to the fluid prescription compared with the below-median group. Conclusion. In clinically stabilised chronic heart failure patients on optimal pharmacological treatment, a larger fluid intake was associated with decreasing thirst without any measurable negative effects on signs and symptoms of heart failure, diuretic use or physical capacity. Thus, a more liberal fluid intake may be advisable in chronic heart failure patients who have been stabilised after an initial unstable clinical state. Relevance to clinical practice. Nurses involved in the care for patients with heart failure known how troublesome thirst can be and how difficult it can be to follow a restricted fluid intake. This study indicates that it is possible to reassess and recommend a less strict fluid intake in stabilised patients with chronic heart failure. © 2008 The Authors.
