    ABSTRACT: BACKGROUND AND AIMS: The ESC/ESH guidelines for arterial hypertension recommend using statins for patients with high cardiovascular (CV) risk for both secondary and primary prevention. A recent meta-analysis, combining previous studies on statins, concluded that they are associated with a 9% increased risk of incident type 2 diabetes mellitus (DM). There is no information on whether statins increase incidence of DM in primary prevention. METHOD AND RESULTS: We evaluated risk of incident DM in relation to statin prescription in 4750 hypertensive, non-diabetic outpatients (age 58.57 ± 9.0 yrs, 42.3% women), from the CampaniaSalute Network, without chronic kidney disease more than grade 3, free of prevalent CV disease and with at least 12 months of follow-up. DM was defined according to ADA criteria. At the end of follow-up period (55.78 ± 42.5 months), 676 patients (14%) were on statins. These patients were older (62.54 ± 7.3 vs 57.91 ± 9.1 yrs; p < 0.0001), more often female (49% vs 41.2%; p = 0.0001), with higher initial total cholesterol (217.93 ± 44.3 vs 205.29 ± 36.6 mg/dl), non-HDL cholesterol (167.16 ± 44.5 vs 155.18 ± 36.7 mg/dl) and triglycerides (150.69 ± 85.2 vs 130.98 ± 72.0 mg/dl; all p < 0.0001) than patients no taking statins, without other differences in clinical and laboratory characteristics. At the end of follow-up, prevalence of DM was 18.1% among patients on statins and 7.2% among those without lipid-lowering therapy (p < 0.0001). However, incident DM was 10.2% in patients on statins and 8.7% in those free of statin therapy (NS). CONCLUSION: In real-life outpatient environment, statin prescription for primary prevention is not associated with increased risk of incident DM. Clinical trial registration identifier: NCT01077037.

    ABSTRACT: Background Fibro-calcification of the mitral annulus (MAC) has been associated with increased risk of ischemic stroke in general populations. This study was performed to assess whether MAC predicts incidence of ischemic stroke in treated hypertensive patients with left ventricular hypertrophy (LVH).Methods Baseline and follow-up clinical and echocardiographic parameters were assessed in 939 hypertensive patients with electrocardiogram (ECG) LVH participating in the Losartan Intervention for Endpoint reduction in hypertension (LIFE) echocardiography substudy (66±7 years; 42% women; 11% with diabetes) who did not have aortic or mitral valve stenosis or prosthesis.ResultsMAC was found in 458 patients (49%). Patients with MAC were older (68±7 vs. 65±7 years); were more often women (47% vs. 37%); had higher baseline systolic blood pressure (BP) (175±14 vs. 172±15mm Hg), left atrial diameter (4.0±0.5 vs. 3.8±0.6cm), and left ventricular mass index (58±13 vs. 55±12g/m(2.7)) and included more patients with proteinuria (30% vs. 21%; all P < 0.01). During a mean follow-up of 4.8 years, 58 participants had an ischemic stroke. Risk of incident ischemic stroke was significantly related to presence of MAC (log rank = 9; P < 0.01). In multivariable Cox regression analysis models, MAC was associated with increased risk of ischemic stroke (hazard ratio = 1.78-2.35), independent of age, baseline or time-varying systolic BP, prevalence or incidence of atrial fibrillation, history of previous cerebrovascular disease, and other well-recognized confounders, such as sex, time-varying left ventricular mass, left atrial diameter, and urinary albumin/creatinine ratio (all P < 0.05).ConclusionsMAC is common in treated hypertensive patients with ECG LVH and is an independent predictor of incident ischemic stroke.

    ABSTRACT: Objective Weight loss improves cardiac abnormalities associated with severe obesity. We evaluated the impact of weight loss following laparoscopic gastric bypass (LGBP) on left ventricular (LV) geometry and function in obese patients. Methods Twenty-six patients with severe obesity (41 ± 8 years, 50% women) underwent Doppler echocardiograms before and after LGBP, to measure LV geometry, excess of LV mass relative to hemodynamic load and systolic and diastolic function. Results Pre-operatively, 85% of patients exhibited LVH, and 62% hypertension and metabolic syndrome, reflecting high cardiometabolic risk. After 8 ± 4 months of follow-up, the average weight loss was 19 ± 8%. Weight loss was significantly associated with improved metabolic parameters and reduced heart rate (−9 bpm), systolic (−11 mmHg) and diastolic (−6 mmHg) blood pressure (all p < 0.02). After surgery, there was significant reduction in relative wall thickness (0.43 ± 0.07 versus 0.39 ± 0.06), LV mass index (63 ± 14 g/m2.7 versus 49 ± 10 g/m2.7) and excess of LV mass in relation to hemodynamic load (all p < 0.004). LVH remained in 54% of patients, hypertension in 23% and metabolic syndrome in 27%. Ejection fraction and Doppler indices of diastolic function did not change significantly, even after adjusting for changes in heart rate. All favorable changes in LV geometry and function were also confirmed in the subgroup with <9 month follow-up (median), whereas no further improvement could be detected in patients with longer follow-up. Conclusions In patient with severe obesity, LV geometry and systolic function improved rapidly after LGBP, without evidence of further improvement during prolonged follow-up.

    ABSTRACT: Pulse pressure/stroke volume indexed to height(2.04) (PP/SVi) is a validated measure of arterial stiffness, but its relation to carotid atherosclerosis is unknown. Clinical, echocardiographic, and carotid ultrasound data from 6,209 hypertensive patients without prevalent cardiovascular (CV) disease in the Campania Salute Network were analyzed. The population was grouped into tertiles of PP/SVi. From carotid ultrasound, peak and mean intima-media thickness (IMT) and presence of carotid plaques in the common and internal carotid arteries were reported. Increasing PP/SVi tertile was associated with a parallel increase in age, blood pressure, total serum cholesterol and the number of antihypertensive drugs used (all P < 0.01). Higher PP/SVi was also associated with greater peak and mean IMT (all P < 0.01), also when adjusting for age, gender, blood pressure, lipid profile, and diabetes mellitus (all P < 0.01). Similarly, compared to the lower PP/SVi tertile, the multiple adjusted prevalence ratio of carotid plaque was 7 (95% confidence interval (CI) 1-13, P < 0.03) in the middle tertile and 21 (95% CI 15-28, P < 0.0001) in the upper tertile, independently of confounders. In treated hypertensive patients participating in the Campania Salute Network, higher PP/SVi is associated with carotid atherosclerosis independent of well-known clinical confounders.

    ABSTRACT: Metabolic syndrome (MetS) is associated with uncontrolled blood pressure (BP), despite use of aggressive therapy. This study was performed to assess whether the use of different classes of antihypertensive drugs might influence this association. We evaluated risk of uncontrolled BP (BP ≥ 140/90 mmHg under antihypertensive treatment) at the time of the last available visit, after a mean follow-up of 5 years in 4612 hypertensive patients without prevalent cardiovascular disease (43% women, 53 ± 11 years) from the Campania Salute Network. At the time of the first visit, prevalence of MetS was associated with 43% increased risk of follow-up uncontrolled BP, independent of significant confounders and without a significant impact of specific classes of antihypertensive medications. At the time of the last available visit, patients with MetS had more often uncontrolled BP, despite more aggressive treatment. After adjusting for demographics, risk factors and number of antihypertensive medications, risk of uncontrolled BP was reduced with increased prescription of diuretics [DRTs; odds ratio (OR) 0.73, 95% confidence interval (CI) 0.62-0.86], renin-angiotensin system blockers [RAS-blockers (Angiotensin-converting enzyme-inhibitors or angiotensin receptor blockers); OR 0.77, 95% CI 0.66-0.91] and statins (OR 0.79, 95% 0.68-0.92, all P < 0.05), without significant impact of the other classes of medications. Despite the use of increased number of medications, hypertensive patients with MetS are at higher risk of uncontrolled BP. Among classes of antihypertensive medications, increased prescriptions of DRTs, RAS-blockers and also statins decrease the probability of poor BP control.

    ABSTRACT: The aim of this study was to evaluate whether diabetes (DM) and impaired fasting glucose (IFG) were associated with early alterations in left ventricular geometry and function in a large population of adolescents and young adults independently of major confounders. We analyzed echocardiographic data of 1,624 14- to 39-year-old participants (mean age 26.6 ± 7.7 years; 57% female) without prevalent cardiovascular disease from the fourth Strong Heart Study examination; 179 (11%) participants had DM and 299 (18%) had IFG. Participants with DM and IFG were older and more often obese and hypertensive than participants with normal fasting glucose (NFG) (all P < 0.05). After adjustment for age, sex, systolic blood pressure, and body fat, diabetic and IFG participants had higher left ventricular mass index than those with NFG (41.5 ± 8.7 and 39.6 ± 9.2 vs. 35.6 ± 7.8 g/m(2.7)) and reduced stress-corrected midwall shortening (98 ± 8.6 and 99 ± 7.5 vs. 101 ± 8.5%; all P < 0.05). The prevalence of left ventricular hypertrophy was higher in DM (20%) and IFG (17%) than in NFG participants (12%; P < 0.05). Compared with the other groups, DM was also associated with higher prevalence of inappropriate left ventricular mass, concentric geometry, and more diastolic abnormalities independently of covariates (all P < 0.05). In a population of adolescents and young adults, DM is independently associated with early unfavorable cardiovascular phenotype characterized by increased left ventricular mass, concentric geometry, and early preclinical systolic and diastolic dysfunction; early cardiovascular alterations are also present in participants with prediabetes.

    ABSTRACT: BACKGROUND AND AIMS: Metabolic syndrome (MetS) is a complex condition characterized by different phenotypes, according to the combinations of risk factors and is associated with cardiovascular abnormalities. Whether control of MetS components by treatment produces improvement in the associated cardiovascular abnormalities is unknown. We investigated whether partial control of components of MetS was associated with less echocardiographic abnormalities than the complete presentation of MetS based on measured components. METHODS AND RESULTS: We evaluated markers of echocardiographic preclinical cardiovascular disease in MetS (ATP III) defined by measured components or by history of treatment, in 1421 African-American and 1195 Caucasian non-diabetic HyperGEN participants, without prevalent cardiovascular disease or serum creatinine >2 mg/dL. Of 2616 subjects, 512 subjects had MetS by measured components and 328 by history. Hypertension was found in 16% of participants without MetS, 6% of those with MetS by history and 42% of those with MetS by measured components. Obesity and central fat distribution had similar prevalence in both MetS groups (both p < 0.0001 vs. No-MetS). Blood pressure was similar in MetS by history and No-MetS, and lower than in MetS by measured components (p < 0.0001). LV mass and midwall shortening, left atrial (LA) dimension and LA systolic force were similarly abnormal in both MetS groups (all p < 0.0001 vs. No-MetS) without difference between them. CONCLUSIONS: There is a little impact of control by treatment of single components of MetS (namely hypertension) on echocardiographic abnormalities. Lower blood pressure in participants with MetS by history was not associated with substantially reduced alterations in cardiac geometry and function.

    ABSTRACT: Left-ventricular hypertrophy (LVH) is a marker of organ damage in hypertension and helps stratifying cardiovascular risk. Initial left-ventricular mass (LVM) is also a predictor of progression to hypertension, independently of initial blood pressure (BP) and other confounders. To evaluate whether baseline LVM can influence BP control in treated hypertension. We evaluated risk of uncontrolled BP (>140 or 90 mmHg under at least two medications), in relation to initial LVM in 4693 hypertensive outpatients (mean age 53±11 years, 43% women, 5% diabetic), without prevalent cardiovascular disease, from the Campania Salute Network. Uncontrolled BP was found in 2240 patients (48%). Participants with initial LVH were more often men, older, diabetic, had higher initial BP, fasting glucose, uric acid and triglycerides, and lower heart rate (HR), high-density lipoprotein-cholesterol and glomerular filtration rate than those without LVH (all P<0.05). Of 1440 patients with initial LVH, 803 (56%) were uncontrolled at follow-up compared to 44% without LVH (P<0.0001). In multivariate analyses, odds of uncontrolled BP increased with higher baseline systolic BP [odds ratio (OR)=1.13×5 mmHg, 95% confidence interval (CI) 1.10-1.15], HR (OR=1.04×5 beats/min, 95% CI 1.01-1.07), BMI (OR=1.03×kg/m, 95% CI 1.01-1.04), LVM index (OR=1.05×5 g/m, 95% CI 1.01-1.10) and prevalence of diabetes (OR=5.22, 95% CI 3.52-7.76; all P<0.05) independently of age, sex, metabolic parameters and number of antihypertensive meds (P>0.1). Among medication classes, only angiotensin-converting enzyme inhibitors or angiotensin receptor blockers were associated with lower risk of uncontrolled BP (OR=0.83, 95% CI 0.71-0.96; P=0.01), independently of covariates. In a population of treated hypertensive patients, initial LVM is a significant predictor of uncontrolled BP, independently of major risk factors and antihypertensive therapy.

    ABSTRACT: Left ventricular (LV) mass (LVM) is the most important information requested in hypertensive patients referred for echocardiography. However, LV function also predicts cardiovascular (CV) risk independent of LVM. There is no evidence that addition of LV function significantly improves model prediction of CV risk compared with LVM alone. Thus, composite fatal and nonfatal CV or cerebrovascular events were evaluated in 5380 hypertensive outpatients (2336 women, 298 diabetics, and 1315 obese subjects) without prevalent CV disease (follow-up: 3.5+/-2.8 years). We compared 5 risk models using Cox regression and adjusting for age and sex: (1) LV mass normalized for height in meters(2.7) (LVMi); (2) LVMi, concentric LV geometry, by relative wall thickness (>0.43), ejection fraction, and transmitral diastolic pattern (by thirtiles of mitral deceleration index); (3) LVMi, LV geometry, midwall shortening, and mitral deceleration index thirtiles; (4) as No. 2 with the addition of left atrial dilatation (>23 mm); and (5) as No. 3 with the addition of left atrial dilatation. Individual hazard functions were compared using receiving operating characteristic curves and z statistics. Areas under the curves increased from 0.60 in the model with the sole LVMi to 0.62 in the others (all P values for differences were not significant). The additional information on systolic and diastolic function decreased the contribution (Wald statistics) of LVMi in the Cox model without improving the model ability to predict CV risk. We conclude that risk models with inclusion of information on LV geometry and systolic and diastolic function, in addition to LVMi, do not improve the prediction of CV events but rather redistribute the impact of individual predictors within the risk variance.
