Patients with acute coronary syndrome (ACS) and concomitant noncoronary atherosclerosis have a high risk of major adverse cardiovascular events (MACEs) and death. The impact of lipid lowering by ...proprotein convertase subtilisin–kexin type 9 inhibition in such patients is undetermined.
This pre-specified analysis from ODYSSEY OUTCOMES (Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab) determined whether polyvascular disease influenced risks of MACEs and death and their modification by alirocumab in patients with recent ACS and dyslipidemia despite intensive statin therapy.
Patients were randomized to alirocumab or placebo 1 to 12 months after ACS. The primary MACEs endpoint was the composite of coronary heart disease death, nonfatal myocardial infarction, fatal or nonfatal ischemic stroke, or unstable angina requiring hospitalization. All-cause death was a secondary endpoint.
Median follow-up was 2.8 years. Of 18,924 patients, 17,370 had monovascular (coronary) disease, 1,405 had polyvascular disease in 2 beds (coronary and peripheral artery or cerebrovascular), and 149 had polyvascular disease in 3 beds (coronary, peripheral artery, cerebrovascular). With placebo, the incidence of MACEs by respective vascular categories was 10.0%, 22.2%, and 39.7%. With alirocumab, the corresponding absolute risk reduction was 1.4% (95% confidence interval CI: 0.6% to 2.3%), 1.9% (95% CI: −2.4% to 6.2%), and 13.0% (95% CI: −2.0% to 28.0%). With placebo, the incidence of death by respective vascular categories was 3.5%, 10.0%, and 21.8%; the absolute risk reduction with alirocumab was 0.4% (95% CI: −0.1% to 1.0%), 1.3% (95% CI: −1.8% to 4.3%), and 16.2% (95% CI: 5.5% to 26.8%).
In patients with recent ACS and dyslipidemia despite intensive statin therapy, polyvascular disease is associated with high risks of MACEs and death. The large absolute reductions in those risks with alirocumab are a potential benefit for these patients.

Introduction
As several international guidelines on hypertension have now recommended, singlepill/fixed-dose combination antihypertensive therapies may be particularly beneficial as firstline therapy ...in high-risk patients, in whom more rapid and pronounced blood pressure (BP) control is desired. Upon the single-pill combination of amlodipine and valsartan becoming available, the authors conducted this international, observational study to evaluate its efficacy and safety in a real-life practice setting.
Methods
This prospective, open-label, postmarketing surveillance study enrolled adults with arterial hypertension (systolic BP >140 mmHg and/or diastolic BP >90 mmHg) who were prescribed antihypertensive therapy with single-pill combination amlodipine/valsartan 5/80, 5/160, or 10/160 mg once daily. Patients were observed over a 3-month period (12 weeks) with approximately monthly intervals between clinic visits.
Results
A total of 8336 patients completed all study visits and were included in the efficacy analysis. Mean age was 54.7 years and 83.4% of patients had received prior antihypertensive therapy. BP reductions were dose related. Overall, mean BP was reduced from 165.0/99.3 mmHg at baseline to 128.7/80.4 mmHg at 12 weeks (36.3/18.9 mmHg;
P
<0.0001). The magnitude of BP reduction rose with increasing severity of baseline BP. Control of BP (<140/90 mmHg) was achieved in 77.7% of patients. Efficacy was consistent in subgroups of patients with comorbidities and regardless of whether patients were previously treated with monotherapy or combination therapy. Adverse events were reported in 5.3% of patients. The incidence of edema declined from 10.4% at baseline to 8.5% at study end.
Conclusion
Single-pill combination amlodipine/valsartan safely and effectively reduced BP across all hypertension grades and allowed the vast majority of patients to achieve BP goals.
Specific features of the procedures involved in chemical analysis (sampling, sample preparation, matrix and impurities identification, quantitative analysis) are considered, and their effect on the ...uncertainty of the result of a quantitative determination of the component of interest is discussed.
In the paper we discuss one of the approaches to modeling and distributed simulation of hybrid systems. We use hybrid state machines to model complex interdependencies between discrete and continuous ...time behaviors. This framework is fully supported by UML-RT/Java tool AnyLogic developed at Experimental Object Technologies (
http://www.xjtek.com). We use high level architecture (HLA) standard for distributed simulation, as a communication and synchronization media for distributed hybrid simulation components. We present a new technique (remote predicate evaluation (RPE)) for distributed modeling of hybrid systems that is applicable to a wide class of simulations. RPE integration with AnyLogic tool and HLA is also considered.
To compare the efficacy of indapamide sustained release (SR) 1.5 mg and enalapril 20 mg at reducing left ventricular mass index (LVMI) in hypertensive patients with left ventricular hypertrophy ...(LVH).
The LIVE study (left ventricular hypertrophy regression, indapamide versus enalapril) was a 1 year, prospective, randomized, double-blind study. For the first time, a committee validated LVH before inclusion, provided on-going quality control during the study, and performed an end-study reading of all echocardiograms blinded to sequence.
European hospitals, general practitioners and cardiologists.
Hypertensive patients aged > or = 20 years with LVH (LVMI in men > 120 g/m2; LVMI in women > 100 g/m2). Data were obtained from 411 of 505 randomized patients.
Indapamide SR 1.5 mg, or enalapril 20 mg, daily for 48 weeks.
LVMI variation in the perprotocol population.
Indapamide SR 1.5 mg significantly reduced LVMI (-8.4 +/- 30.5 g/m2 from baseline; P< 0.001), but enalapril 20 mg did not (-1.9 +/- 28.3 g/m2). Indapamide SR 1.5 mg reduced LVMI significantly more than enalapril 20 mg: -6.5 g/m2, P = 0.013 (-4.3 g/m2 when adjusted for baseline values; P = 0.049). Both drugs equally and significantly reduced blood pressures (P< 0.001), without correlation with LVMI changes. Indapamide SR progressively reduced wall thicknesses throughout the 1-year treatment period. In contrast, the effect of enalapril observed at 6 months was not maintained at 12 months.
Indapamide SR 1.5 mg was significantly more effective than enalapril 20 mg at reducing LVMI in hypertensive patients with LVH.
