Relation of improvement in estimated glomerular filtration rate with atorvastatin to reductions in hospitalizations for heart failure (from the Treating to New Targets [TNT] study).

Impaired kidney function often accompanies heart failure (HF) and is associated with a worse prognosis. This post hoc analysis of the Treating to New Targets (TNT) trial examined whether the observed decrease in HF hospitalizations with high- compared to low-dose atorvastatin could be related to improvements in kidney function. Of 10,001 TNT participants, 9,376 had estimated glomerular filtration rate (eGFR) measurements at baseline and 1 year and were included in this analysis. The association of change in year-1 eGFR and subsequent HF hospitalization was examined using Cox regression models. In total 218 participants developed subsequent HF hospitalization. Little change in eGFR occurred over 1 year in the atorvastatin 10-mg group, whereas eGFR improved in the 80-mg group by 1.48 ml/min/1.73 m(2) (95% confidence interval 1.29 to 1.67, p <0.0001). Subsequent HF was preceded by a decrease in eGFR over 1 year compared to modest improvement in those without subsequent HF (-0.09 ± 7.89 vs 0.81 ± 6.90 ml/min/1.73 m(2), p = 0.0015). After adjusting for baseline eGFR, each 5-ml/min/1.73 m(2) increase in eGFR at 1 year was associated with a lower risk of subsequent HF hospitalization (hazard ratio 0.85, 95% confidence interval 0.77 to 0.94, p = 0.002). This relation was independent of treatment effect or change in low-density lipoprotein cholesterol level at 1 year. In conclusion, treatment with high- compared to low-dose atorvastatin was associated with improvement in eGFR at 1 year, which was related to a decrease in subsequent HF hospitalization. This suggests that improvement in kidney function may be related to the beneficial effect of high-dose atorvastatin on HF hospitalization.

Predicted coronary heart disease risk reduction and dual blood pressure/cholesterol goal attainment in patients with hypertension treated in real-world clinical practice.

Hypertension and dyslipidemia are highly co-prevalent, but often poorly controlled, coronary heart disease (CHD) risk factors. A retrospective cohort study was conducted between January 2004 and April 2008 to compare estimated 10-year CHD risk reduction and dual blood pressure and low-density lipoprotein cholesterol goal attainment (Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure and Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults [Adult Treatment Panel III]) in patients with a first prescription for amlodipine monotherapy, co-prescribed amlodipine + statin, or single-pill amlodipine/atorvastatin. In total, 2739 patients were prescribed amlodipine monotherapy, 653 were co-prescribed amlodipine + statin, and 227 were prescribed single-pill amlodipine/atorvastatin. Baseline CHD risk was similar in all 3 cohorts (11.0%-12.5%). Relative CHD risk reduction was greater in those prescribed single-pill amlodipine/atorvastatin (24.5%) compared with amlodipine monotherapy (14.4%, P<.01), and co-prescribed amlodipine + statin (18.4%, P=.01). The findings were driven by greater dual goal attainment for patients prescribed single-pill amlodipine/atorvastatin (50.2%) compared with amlodipine monotherapy (31.7%, P<.05) and co-prescribed amlodipine + statin (37.5%, P<.05).

Preservation of ventricular function in amateur athletes after completion of a marathon.

BACKGROUND: Previous studies have demonstrated the development of impaired systolic function and new segmental wall motion abnormalities following completion of ultraendurance events. Limited information is available on the effect of an endurance event such as a marathon on the left ventricular indices and hemodynamics. METHODS: We examined 45 patients (26 men, 19 women with the average age of 35+/- 8 years) who successfully trained and completed the 2001 Chicago Marathon (26.2 miles). Transthoracic 2-dimensional and Doppler echocardiography (TTE) was preformed prior to the marathon (17+/-10.7 days), immediately following the marathon (71+/-42 minutes), and at follow-up (29+/-12.9 days). RESULTS: Left ventricular end diastolic volumes declined immediately post marathon and returned to baseline at the one-month follow-up. Ejection fraction was maintained and no regional wall motion abnormalities were identified at any time point. Diastolic parameters decreased immediately post marathon but returned to baseline during follow-up principally reflecting a change in volume status. CONCLUSION: Marathon running by a group of well-trained recreational athletes does not result in impairment of left ventricular systolic or diastolic function.
