- Context The cardiovascular (CV) risk profile is worsened in primary hyperparathyroidism (PHPT), and CV mortality is related to serum calcium levels. It is unknown whether CV mortality is increased in the most common form of PHPT and whether the increased CV risk is reversible after surgery. Objective To investigate reversibility of echocardiographic variables in patients with mild PHPT who were randomized to observation without surgery or operation, and followed for 2 years. Design/Setting/Patients Forty-nine patients (mean age 63 ± 7 years, 8 men) who had performed the 2-year visit in a randomized study on mild PHPT (serum calcium at baseline 2·65 ± 0·09 mm) (observation) vs 2·67 ± 0·06 mm (surgery) and where echocardiography had been performed, participated in the study. Results Calcium and parathyroid hormone (PTH) levels were normalized following surgery and were stable in the observation group. PTH levels at baseline were highly correlated with ventricular mass. Detailed echocardiography revealed a minor and borderline significant treatment effect of surgery on left ventricular mass index (LVMI) compared to observation (P = 0·066) and a significant 11% reduction in diastolic dimension of the interventricular septum (IVSd-mean) in the surgery group (P < 0·01), with no alterations in the observation group. Conclusions Based on detailed echocardiographic measures over a 2-year observation period, we found only minor differences between the two groups. However, the potential treatment effect on LVMI and the within-group differences in IVSd-mean suggest that longer follow-up may yield larger and clinically important differences.

- OBJECTIVES: To determine the additional prognostic value of mitral regurgitation (MR) over B-type natriuretic peptide (BNP), left ventricular ejection fraction (LVEF) and clinical characteristics in patients with acute coronary syndromes (ACS). DESIGN: Long-term follow-up in a prospective ACS cohort with Doppler-assessed MR, echocardiographically-determined LVEF and plasma BNP levels by ELISA. SETTING: Single-centre university hospital. PATIENTS: 725 patients with ACS. MAIN OUTCOME MEASURES: Death and readmission for congestive heart failure. RESULTS: During a median follow-up of 98 months, 235 patients (32%) died. Significant MR (grade >1 of 4) was found in 90 patients (12%). In a multivariate model including MR grade >1, LVEF <0.40 and BNP >373 pg/ml (75th percentile), MR was significantly associated with long-term mortality (HR 2.28, 95% CI 1.67 to 3.12; p<0.0001). When also adjusting for conventional risk factors, MR remained significantly associated with mortality (HR 1.53, 95% CI 1.06 to 2.19; p=0.02), as well as with congestive heart failure (HR 2.08, 95% CI 1.29 to 3.35; p=0.003). CONCLUSIONS: MR is common in patients with ACS, provides independent risk information and should be taken into account in the evaluation of the long-term prognosis.

- BACKGROUND: Acute phase hyperglycaemia has been associated with increased mortality in patients with acute coronary syndrome. We investigated whether the predictive value of admission hyperglycaemia for mortality differs between diabetics and non-diabetics with acute coronary syndrome. METHODS: Patients with acute coronary syndrome (n=1957) were followed up prospectively for 45 months. Patients were stratified into quartile groups defined by admission plasma glucose and hyperglycaemia was defined as plasma glucose of >9.4 mmol/l, which was the cut-off value for the 4th quartile. The relationship between admission hyperglycaemia and short-term (< or =30 day) and late (>30 day) mortality was analysed. RESULTS: Of 1957 patients, 22% had a history of diabetes. Among patients without diabetes, those with hyperglycaemia had both a higher 30-day mortality rate (20.2% vs. 3.5%, p<0.0001) and late mortality rate (19.1% vs. 11.7%, p=0.007). Hyperglycaemic patients with diabetes had a higher late mortality rate than diabetic patients with plasma glucose of < or =9.4 mmol/l (29.3% vs. 14.9%, p=0.001). Of patients with hyperglycaemia at admission, those without diabetes had a higher 30-day mortality rate compared with those with diabetes (p=0.002). CONCLUSION: Admission hyperglycaemia is a strong risk factor for mortality in patients with acute coronary syndrome and may be even stronger than a previous history of diabetes. Hyperglycaemic patients without recognised diabetes have a higher short-term mortality risk than hyperglycaemic patients with known diabetes.

- ObJECTIVES: To evaluate the association between glycometabolic status in the acute phase and 21/2 years later in patients with acute coronary syndrome (ACS). METHODS: Non-diabetic patients (n = 762) presenting with ACS were prospectively followed up for 21/2 years. Patients were stratified by admission plasma glucose (<6.1 mmol/l, 6.1 - 6.9 mmol/l and >or=7.0 mmol/l) and HbA1c (or=5.5%). The predictive value of glucose levels >or= 7.0 mmol/l and HbA1c >or= 5.5% for glycometabolic disturbance (i.e. diabetes or impaired fasting glycaemia (IFG)) was analysed. RESULTS: Of 762 patients, 13% had a diagnosis of diabetes and 16% had IFG at follow-up. The prevalence of glycometabolic disturbance at follow-up increased with increasing plasma glucose at admission, from 19% in patients with < 6.1 mmol/l to 42% in patients with >or= 7.0 mmol/l. Sixty-one percent of patients with HbA1c >or= 5.5% had glycometabolic disturbance after 21/2 years compared to only 25% of those with HbA1c < 5.5%. CONCLUSION: Non-diabetic patients with ACS and hyperglycaemia are at high risk for developing glycometabolic disturbance. HbA1c may be an even stronger predictor of glycometabolic disturbance than plasma glucose.

- Background: Atrial fibrillation (AF) is common in patients with acute coronary syndromes (ACS). We aimed to describe the value of the CHADS(2) (congestive heart failure, hypertension, age >= 75 years, diabetes, prior stroke or transient ischemic attack) score as a risk assessment tool for mortality and stroke in patients with ACS, irrespective of the presence or absence of AF. Methods: Consecutive patients with ACS admitted to the coronary care unit were prospectively included in a risk stratification study. We calculated the CHADS(2) scores from the data collected at admission, and all patients were followed until January 1, 2007, or death. Results: Of 2,335 patients with ACS in this study, 442 (age 71 +/- 8 years, 142 women) had AF. Their mean CHADS(2) score was 1.6 +/- 1.4 vs 1.0 +/- 1.1 in patients without AF (P < .0001). The all-cause mortality at 10 years was strongly associated with the CHADS(2) score in patients with AF (hazard ratio [HR] and 95% CI per unit increase in the six-grade CHADS(2) score, 1.21 [1.07-1.36]; P = .002), hut the same association was also present in patients without AF (HR 1.38 [1.28-1.48], P < .0001), after adjustment for potential confounders. The more complicated GRACE (Global Registry Of Acute Coronary Events) risk score provided a better prediction for short- and long-term mortality than the simpler CHADS(2) score (P < .0001). Hospitalization for stroke was significantly associated with the CHADS(2) score in patients without AF (but not in those with AF) after adjustment (HR 1.46 [1.27-1.68], P <.0001). Conclusions: In patients with ACS, AF is associated with poor prognosis. The CHADS(2) score developed for AF has even greater prognostic value in patients who do not have AF, and it may help to identify patients with high risk for subsequent stroke or death and a need for optimization of risk-reducing treatment.

- Abstract BACKGROUND: The gender perspectives of the triage of acute coronary syndromes (ACS) in a community are insufficiently explored. METHODS: Patients (n=3224) with symptoms of ACS, in whom ECG was sent by the ambulance crew to a coronary care unit (CCU)/ cath lab, were investigated in the municipality of Göteborg in 2004-2007. Background, triage priority, investigations and treatment were analysed (p-values age adjusted) in relation to gender. Data were compared with three published studies (1995-2002: Surveys 1-3). RESULTS: Women were directly admitted to the CCU significantly less frequently than men (23 versus 35%, p<0.0001). Adjusted for ECG findings, age, symptoms and medical history, odds ratio and 95% confidence limits (for direct admission; men versus women) were 0.61; 0.46-0.82. SURVEY 1: Patients with ACS, aged <80, in CCU at a university hospital (n=1744). Only minor differences between women and men, with regard to investigations and treatment, were found. SURVEY 2: Patients discharged from hospital (dead or alive) with AMI, regardless of type of ward (n=1423). Fewer women than men were admitted to CCU and fewer women underwent coronary angiography (21% versus 40%; p=0.02) and coronary revascularisation (12% versus 27%; p=0.004). SURVEY 3: Patients with symptoms of AMI (n=930) and patients with a confirmed AMI (n=130) from a pre-hospital perspective. Women tended to be given lower priority than men both by the ambulance dispatchers and by the ambulance crew. CONCLUSION: In our practice setting, men are given priority over women in admission to CCU, but no gender differences are seen thereafter.

- Coronary artery bypass grafting (CABG) is generally accepted as effective in relieving patients from angina pectoris, and in improving survival in subgroups. However, subset evaluations of myocardial ischemia and exercise capacity after CABG are scarce. The aim of this study was to determine the outcome of CABG in terms of exercise capacity and stress ECG findings in subgroups of patients.
