BACKGROUND Heart rate recovery (HRR) has been shown to predict cardiovascular disease mortality. HRR is delayed in hypertension, but its association with prehypertension (PHT) has not been well studied. METHODS The study population consisted of 683 asymptomatic individuals (90% men, aged 47±7.9 years). HRR was defined as peak heart rate minus heart rate after a 2-minute rest. PHT was categorized into stage I (systolic blood pressure (SBP) 120-129mm Hg or diastolic BP (DBP) 80-84mm Hg) or stage II (SBP 130-139mm Hg or DBP 85-89mm Hg). Logistic regression was used to generate odds ratios (ORs) for the relationship between HRR and PHT. RESULTS The mean HRR was lower in the PHT groups than in those who were normotensive (60 bpm and 58 bpm in stages I and II PHT vs. 65 bpm in normal BP; P <0.01). Persons with PHT were more likely to be in the lowest quartile of HRR compared with those with normal BP (adjusted OR, 3.80 and 95% confidence interval [CI], 1.06, 13.56 for stage II PHT and adjusted OR, 3.01 and 95% CI 1.05, 8.66 for stage I PHT). In a fully adjusted model, HRR was still significantly associated with both stages of PHT. CONCLUSION Among asymptomatic patients undergoing stress testing, delayed HRR was independently associated with early and late stages of PHT. Further studies are needed to determine the usefulness of measuring HRR in the prevention and management of hypertension.

Obesity demonstrates a direct relation with cardiovascular risk and all-cause mortality, while cardiorespiratory fitness demonstrates an inverse relation. In clinical practice, several cardiometabolic (CM) risk factors are commonly measured to gauge cardiovascular risk, but the interaction between fitness and obesity with regard to CM risk has not been fully explored. In this study, 2,634 Brazilian adults referred for employer-sponsored heath exams were assessed. Obesity was defined as body mass index >30 kg/m(2) or waist circumference >102 cm in men or >88 cm in women when body mass index was 25 to 30 kg/m(2). Fitness was quantified by stage achieved on an Ellestad treadmill stress test, with those completing stage 4 considered fit. Hepatic steatosis was determined by ultrasound. CM risk factors were compared after stratifying patients into 4 groups: fit and normal weight, fit and obese, unfit and normal weight, and unfit and obese. Approximately 22% of patients were obese; 12% were unfit. Fitness and obesity were moderately correlated (ρ = 0.38 to 0.50). The sample included 6.5% unfit and normal-weight subjects and 16% fit and obese subjects. In overweight and obese patients, fitness was negatively associated with CM risk (p <0.01 for all values). In fit patients, increasing body mass index was positively associated with CM risk (p <0.01 for all values). In instances of discordance between fitness and obesity, obesity was the stronger determinant of CM risk. In conclusion, fitness and obesity are independently associated with CM risk. The effects of fitness and obesity are additive, but obesity is more strongly associated with CM risk when fitness and obesity are discordant. These findings underscore the need for weight loss in obese patients and suggest an unmeasured benefit of fitness.

BACKGROUND AND AIMS There is concern that statin use may exacerbate nonalcoholic fatty liver disease (NAFLD). We aimed to assess the association of statin use with NALFD and severity of liver fibrosis among NAFLD individuals. METHODS We evaluated 6,385 cross-sectional healthy Brazilian subjects (43 ± 10 years, 79% males) without clinical coronary heart disease between November 2008 and July 2010. NAFLD was diagnosed by ultrasound. Severity of liver fibrosis was predicted by fatty liver index and FIB-4. RESULTS NAFLD prevalence was 36% (n = 2310). Overall 552 (9%) individuals were using statins of whom 49% had NAFLD. Statin users were more likely to be men, older age, and have higher burden of risk factors (p <0.05). In age gender adjusted analysis the odds ratio for NAFLD with statin use was 0.87 (0.61-1.25, p = 0.46) in the presence of metabolic syndrome and 1.08 (0.88-1.32, p = 0.56) in its absence. On further adjustment for metabolic risk factors, LDL and smoking the results remained unchanged (OR: 0.89, 95% CI: 0.65-1.32, p = 0.56 and 0.90 (0.69-1.18, p = 0.46). There was no significant association between statin use and fatty liver index in a subanalysis of NAFLD individuals (71 ± 18 vs. 69 ± 23, p = 0.18). Although FIB-4 was mildly elevated with statin use (1.20 ± 0.51 vs. 1.02 ± 0.46, p <0.001), a multivariate analysis adjusted for age, gender and risk factors revealed statin use was not associated with severe fibrosis (FIB >1.45) (OR 0.88, 95% CI: 0.60-1.29, p = 0.50). CONCLUSIONS The results of this study favor statin use in subjects with NAFLD as its use is not associated with the presence of NAFLD or increased fibrosis.

Middle-aged individuals with favorable levels of all major cardiovascular risk factors (CVRFs) have much lower age-specific risks for incident cardiovascular disease (CVD). However, the relationship of the absence of CVRFs with subclinical CVD and inflammation is not well described. We classified 440 asymptomatic Brazilian men (aged 46+/-7 years) based on the number of CVRFs (smoking, systolic blood pressure > or =130 mm Hg, low-density lipoprotein cholesterol > or =130 mg/dL, high-density lipoprotein cholesterol <40 mg/dL, triglycerides > or =150 mg/dL, fasting glucose > or =100 mg/dL, and waist circumference >102 cm). Only 7% had no CVRFs, whereas 1, 2, 3, and > or =4 CVRFs were observed in 18%, 24%, 21%, and 29%, respectively. In age-adjusted analysis, each lower CVRF profile was associated with lower odds of prevalent coronary artery calcium (odds ratio, 0.75; P=.002) and elevated white blood cell count (odds ratio, 0.70; P<.001). Our study supports the notion that a favorable CVD profile is associated with less underlying atherosclerosis and inflammation and further highlights the importance of primary prevention of CVRFs.

AIMS Non-alcoholic hepatic steatosis (HS) is associated with hypertension and increased cardiovascular risk. While Blood pressure hyper-reactive response (HRR) during peak exercise indicates an increased risk of incident hypertension and increased cardiovascular risk, no data on the association of non-alcoholic HS and HRR exists. In this study, we have evaluated the association of HS with HRR. METHODS We included 13 410 consecutive individuals with a mean age: 42.4  ±  8.9 years, 3561 (26.6%) female with normal resting blood pressure and without a previous diagnosis of hypertension, who underwent symptom limited exercise treadmill test, abdominal ultrasonography and clinical and laboratory evaluation. HS was detected by abdominal ultrasonography. HRR was defined by a peak exercise systolic blood pressure  >220 mmHg and/or elevation of 15 mmHg or more in diastolic blood pressure from rest to peak exercise. RESULTS The prevalence of HS was 29.5% (n  =  3956). Overall, 4.6% (n  =  619) of the study population presented a HRR. Subjects with HS had a higher prevalence of HRR (8.1 vs. 3.1%, odds ratio 2.8, 95% CI 2.4-3.3, P  <  0.001). After adjustment for body mass index, waist circumference, fasting plasma glucose and low density lipoprotein cholesterol, HS (odds ratio 1.4, 95% CI 1.1-1.6, P  =  0.002) remained independently associated with HRR. HS was additive to obesity markers in predicting exercise HRR. CONCLUSIONS Non-alcoholic HS is independently associated with hyper-reactive exercise blood pressure response.

Cardiopulmonary exercise test (CPET) has been gaining importance as a method of functional assessment in Brazil and worldwide. In its most frequent applications, CPET consists in applying a gradually increasing intensity exercise until exhaustion or until the appearance of limiting symptoms and/or signs. The following parameters are measured: ventilation; oxygen consumption (VO2); carbon dioxide production (VCO2); and the other variables of conventional exercise testing. In addition, in specific situations, pulse oximetry and flow-volume loops during and after exertion are measured. The CPET provides joint data analysis that allows complete assessment of the cardiovascular, respiratory, muscular and metabolic systems during exertion, being considered gold standard for cardiorespiratory functional assessment.1-6 The CPET allows defining mechanisms related to low functional capacity that can cause symptoms, such as dyspnea, and correlate them with changes in the cardiovascular, pulmonary and skeletal muscle systems. Furthermore, it can be used to provide the prognostic assessment of patients with heart or lung diseases, and in the preoperative period, in addition to aiding in a more careful exercise prescription to healthy subjects, athletes and patients with heart or lung diseases. Similarly to CPET clinical use, its research also increases, with the publication of several scientific contributions from Brazilian researchers in high-impact journals. Therefore, this study aimed at providing a comprehensive review on the applicability of CPET to different clinical situations, in addition to serving as a practical guide for the interpretation of that test.
