Types and outcomes of cardioversion in patients admitted to hospital for atrial fibrillation: results of the German RHYTHM-AF Study.

BACKGROUND: Atrial fibrillation (AF) accounts for approximately one-third of hospitalizations for cardiac rhythm disturbances. Little is known about the characteristics of current use of cardioversion (CV) and its success rates in clinical practice in Germany. METHODS: As part of the international RHYTHM-AF Study, 655 consecutive patients with documented AF (mean age 68.3 ± 10.5 years, 64.9 % males) who were considered candidates for CV were prospectively enrolled in 22 German hospitals (21 academic/teaching and 1 non-teaching). CV was considered successful if sinus rhythm or atrial rhythm was obtained within 1 day after start of pharmacological CV (PCV) or if sinus rhythm was achieved and maintained for at least 10 min after electrical CV (ECV). RESULTS: Patients with AF considered for CV had ECG in 94.4 %, Holter ECG in 25.8 %, and transesophageal echocardiography (TEE) in 73.1 % of cases. They underwent ECV (after mean 16 h, range 4-48), in 65.3 % and PCV in 6.7 % of patients (amiodarone in 47.7 %, flecainide in 27.3 %, propafenone in 2.3 %) as first CV procedure. No CV was performed in 27.9 %, mainly due to spontaneous CV or pathologic TEE. Primary success rates were 86.7 % for electrical CV and 54.5 % for pharmacological CV. More patients in the ECV group compared to the PCV group received oral anticoagulation at discharge (79.2 vs. 59.1 %, p < 0.001), and at 60 days (77.5 vs. 56.8 %, p < 0.001). Further, at 60 days the proportion of patients in sinus rhythm was not different between groups (ECV 76.8 % vs. PCV 77.3 %). CONCLUSIONS: In large academic centres in Germany, the preferred CV method is electrical, mainly due to its easy access and to its higher success rate for the initial restoration of sinus rhythm. Considering the limitations of the open-label, non-randomised study design, overall short-term success rates appeared higher after ECV compared to PCV during hospitalisation, but not after 60 days.

Atherogenic dyslipidemia as evidenced by the lipid triad: prevalence and associated risk in statin-treated patients in ambulatory care.

OBJECTIVE: The prevalence of atherogenic dyslipidaemia (AD) can be assessed using the lipid triad (low high-density lipoprotein cholesterol [HDL-C] < 35 mg/dl, high triglyceride (TG) levels (≥ 200 mg/dl) and a high total cholesterol HDL-C ratio (TC/HDL-C>5). The aim of the present analysis was (1) to describe the prevalence of the lipid triad, (2) to quantify the associated cardiovascular risk on the basis of the PROCAM score, and (3) to calculate the additional risk reduction that can be obtained by adding nicotinic acid (NA) to a pre-existing statin therapy (model based on the outcomes of a previous randomized controlled study). METHODS: Descriptive post-hoc analysis of the German 4E registry in 24,500 patients receiving statins for primary cardiovascular prevention in ambulatory care. RESULTS: The sample comprised 24,500 patients in primary prevention, who had an overall 10-year risk of 16.2%. The prevalence of patients with lipid triad was 24.0%. The mean estimated risk reduction in the total sample (calculated on the basis of a mean LDL-C decrease by 24.3% and other lipid parameter changes) achieved after 6-week statin treatment was 46.6%, the estimated additional relative risk reduction by NA 45.1% (total effect compared to baseline about 70%). In the lipid triad group, the additional relative risk reduction by NA treatment was 42.9%. Relative treatment effects were consistent, irrespective of age and gender. Limitations of this analysis include the use of the TC/HDL-C ratio instead of the direct small dense LDL-C measurements, and the unknown variations of effect size of NA induced lipid reduction when used in combination with statins. CONCLUSIONS: Our model calculations indicate that the residual risk which persists after statin treatment could be substantially lowered if besides LDL-C also HDL-C and TG would be addressed, e.g. by adding NA to statin therapy. Definitive prospective studies are needed to confirm this hypothesis.

Prevalence and overlap of different lipid abnormalities in statin-treated patients at high cardiovascular risk in clinical practice in Germany.

BACKGROUND: In line with current guideline recommendations, patients at high cardiovascular risk are usually treated with statins for secondary as well as for primary prevention. While many studies investigated treatment goal achievement with regards to low-density lipoprotein (LDL-C) and total cholesterol (TC) there is paucity of data regarding high density lipoprotein (HDL-C), and/or triglycerides (TG). SETTING: Prospective, cross-sectional study (Dyslipidemia International Survey, DYSIS) with data provided by 748 office-based physicians throughout Germany. METHODS: Consecutive patients were eligible for participation, if they were at least 45 years old, currently treated with a statin and had had a documented lipid profile (at least 1 parameter) within the last 6 months. Besides descriptive analyses, logistic regression was performed with backward selection to assess predictors for lipid abnormalities (non-attainment of goals for TC, LDL-C, low HDL-C or elevated TG) classified according to current European Society of Cardiology guidelines. RESULTS: The 4,282 documented patients (98.6% Caucasian, 56.4% male; 86.6% at high cardiovascular risk) were predominantly treated with simvastatin (83.9%), pravastatin (7.7%) or atorvastatin (3.9%), usually with doses equivalent to simvastatin 20-40 mg daily. Non-statins were used in at most 12% of patients. No lipid abnormalities were found in 21.0% of patients, one abnormality in 38.5%, two in 31.9%, and all three in 8.5%. LDL-C goals were not attained in 58.1%, elevated TC was found in 66.6%, low HDL-C in 22.7%, and elevated TG in 47.3%. In the multivariate logistic regression model, non-attainment of LDL-C levels was predicted by hypertension (odds ratio, OR 1.4), current smoking (OR 1.3), sedentary lifestyle (OR 1.3), and female gender (OR 1.3). On the other hand, a reduced risk for missing LDL-C targets was noted in the presence of ischemic heart disease (OR 0.6), diabetes (0.5), higher statin doses, ezetimibe treatment, or specialist care, respectively. CONCLUSION: A substantial proportion of statin-treated patients not only missed targets for LDL-C, but also did not attain the normal levels for HDL-C and/or TG. There is a large disconnect between high prevalence of HDL and/or TG disorders, with or without elevated LDL-C, and utilization of therapies targeting these lipids. Particularly in high-risk patients, additional efforts should be made to improve their lipid profile.

Improvement of hypertension management by structured physician education and feedback system: cluster randomized trial.

INTRODUCTION: We aimed to assess whether hypertension management with a structured physician information program and a feedback system leads to improved blood pressure (BP) control and cardiovascular outcomes. METHODS: Cluster randomized (3 : 1), open, monitored, multicenter trial in Germany. Primary care-based physicians in the information group (IG) received detailed training on hypertension guidelines, feedback on target-level attainment, and a reminder to intensify treatment after each patient visit, whereas the observation/control group (CG) did not receive any such measures. A three-level mixed model was developed. Time-independent level differences between groups, group-independent changes, and nonparallel group-specific changes over time were tested. RESULTS: A total of 15 041 (78.1%) hypertensive patients were in the IG and 4213 (21.9%) in the CG. By 1-year follow-up, 82.9% of patients in the IG and 81.5% in the CG remained in the study. The guideline-oriented BP target was attained by 56.8% in the IG and 52.5% in the CG (+4.3%, P = 0.03), whereas the individual BP target was attained by 57.0% in the IG and 51% in the CG (P = NS). BP control in the IG was achieved 2 months earlier on average. Clinical inertia, defined as the absence of medication changes, despite noncontrol of BP, occurred significantly less often in the IG group. One-year cardiovascular outcomes did not differ between groups. CONCLUSION: The delivery of systematic information in connection with a feedback system reduces clinical inertia and improves guideline adherence. Although compared with earlier studies, the hypertension control rates obtained are higher, there is still considerable room for improvement.

[Effects of long-term antihypertensive therapy with losartan on blood pressure and cognitive function in patients with essential hypertension and other cerebrovascular risk factors (AWARE observational study)]. / Effekte der antihypertensiven Langzeittherapie mit Losartan auf den Blutdruck und die kognitive Funktion bei Patienten mit essentieller Hypertonie und weiteren zerebrovaskulären Risikofaktoren (AWARE-Beobachtungsstudie).

BACKGROUND AND PURPOSE: As arterial hypertension is the most important risk factor for ischemic stroke, the relevant guidelines recommend rigorous treatment to normalize blood pressure. Hypertension can also be associated with cognitive decline and dementia. Therefore, the effect of a long-term therapy with the AT(1) antagonist losartan (+/- hydro chloro thiazide [HCTZ]) on cognitive function in patients with essential hypertension and additional cerebrovascular risk factors was investigated. PATIENTS AND METHODS: Prospective, open observational study in 6,206 adult patients with known essential hypertension and cerebrovascular risk factors (most with a 10-year stroke risk of >or= 20% based on the Framingham Score). Demographic data, blood pressure, selected laboratory parameters, and cognitive function (c.I. test) were determined at baseline and after 3, 6, and 12 months. RESULTS: The patients' mean age was 65.8+/-10.7 years and 46.1% of the patients were male. In addition to treatment with losartan +/- HCTZ, 54.1% of the patients received one or more additional antihypertensive agents. After 1 year of treatment, systolic/diastolic blood pressure fell from its baseline level of 158.1/90.3 mmHg to 137.3/80.6 mmHg (-20.8/-9.7 mmHg). The proportion of patients with no/mild/severe cognitive impairment was 30.0%/30.3%/39.7% at baseline and 34.8%/28.1%/37.1% at the end of the study. In patients with cognitive impairment, fibrinogen and hsCRP (high-sensitive C-reactive protein) levels were significantly elevated. Adverse events (AEs) were reported in 231 patients (3.7%), while serious/nonserious AEs possibly related to the study medication were reported in only six (0.1%) and 38 patients (0.6%), respectively. CONCLUSION: A high proportion of patients with hypertension shows cognitive impairment; therefore, use of appropriate tests to detect this should be considered. The losartan-based antihypertensive treatment increased the proportion of patients with normal cognitive function, reduced blood pressure, and was well tolerated in the primary-care setting.

[Fixed-combination of losartan/hydrochlorothiazide 100 mg/25 mg. Tolerability and efficacy on blood pressure measured in the practice and for 24 hours]. / Fixkombination von Losartan/Hydrochlorothiazid 100 mg/25 mg. Verträglichkeit und Wirksamkeit auf Praxis- und 24-Stunden-Blutdruck.

BACKGROUND: A high proportion of patients with essential hypertension need a combination therapy to reach the therapeutic goal. In the present study, the tolerability and efficacy of a fixed, once daily combination of the AT1 blocker Losartan (100 mg) and the diuretic hydrochlorothiazide (HCTZ) (25 mg) for patients in the real-life situation was investigated. Special consideration was given to the results of ambulatory 24-hourblood pressure (ABP) measurements. METHODS: The open label, prospective non-interventional surveillance study took place from October 2005 to June 2006. A total of 1139 patients over 18 years in age were included whose blood pressures could not be adequately treated with HCTZ alone and for whom an individual dose titration for Losartan and HCTZ had already been performed. RESULTS: The average age (+/- standard deviation) of the patients was 61.2 +/- 11.6 years; 55.8% were men. Comorbidities were common. Specifically, left ventricular hypertrophy was present in 3.1% of the patients, coronary heart disease in 30.1%, chronic heart failure in 11.8% and status post myocardial infarction in 10.5%, respectively. In addition to the Losartan/HCTZ treatment, 61.0% of the patients received a second antihypertensive medicine. After an average treatment duration of 50.4 +/- 17.2 days, the base line systolic blood pressure of 160.8 +/- 16.3 mmHg decreased by 24.0 +/- 17.0 mmHg (-14.4%) and the diastolic blood pressure of 94.4 +/- 9.9 mmHg decreased by 11.8 +/- 10.2 mmHg (-11.8%). For the ABP measurements, the overall average systolic and diastolic blood pressures fell by 16.9 +/- 14.2 mmHg and 8.8 +/-10.3 mmHg, the day average by 17.3 +/- 14.8 mmHg and 9.0 +/- 10.2 mmHg and the night average by 15.1 +/- 17.6 mmHg and 7.8 +/- 11.7 mmHg, respectively. In twelve of the 1139 patients (1.1%), a total of 15 adverse events occurred. A causal connection with the medication was suspected in only in one case (one patient with three). CONCLUSION: The combination of Losartan/HCTZ 100/25 mg, as the exclusive therapy or in addition to other antihypertensive medicines, was for patients, many of whom who had comorbidities, in the real-life situation well tolerated and effective. The efficacy was demonstrated also during the night through ABP.
