Psoriasis Severity

We explored the association between subclinical cardiac organ damage (OD) with comorbidities and psoriasis severity in 53 psoriasis patients on infliximab treatment (age 47 ± 15 years, 30% women) and 99 controls without psoriasis (age 47 ± 11 years, 28% women). Cardiac OD was assessed by echocardiography as the presence of increased left ventricular (LV) relative wall thickness (RWT), LV hypertrophy or dilated left atrium. Psoriasis severity was graded using the psoriasis area and severity index (PASI). The prevalence of hypertension was 66% in psoriasis vs. 61% in controls (p = 0.54) and cardiac OD seen in 51 and 73%, respectively (p = 0.007). Psoriasis was associated with a lower prevalence of cardiac OD (odds ratio (OR) 0.32, 95% confidence interval (CI) 0.13–0.77, p = 0.01) independent of age, sex, smoking, body mass index, and hypertension. Among psoriasis patients, hypertension was associated with increased risk of subclinical cardiac OD (OR 6.88, 95% CI 1.32–35.98, p = 0.02) independent of age, sex, and body mass index. PASI at treatment initiation was associated with a higher RWT at follow-up, independent of sex, age, and hypertension (β 0.36, p = 0.006) while no association with current PASI was found. In conclusion, cardiac OD was less prevalent in psoriasis patients on infliximab treatment than controls. Hypertension was the major covariable for subclinical cardiac OD in psoriasis.

The aim – to study the features of structural and functional remodeling of the left ventricle in patients suffering from arterial hypertension with concomitant hypothyroidism and to determine clinical and past medical history and laboratory factors associated with their development. Materials and methods. 50 patients suffering from hypertension with concomitant hypothyroidism were enrolled into the study. Depending on the level of thyroid stimulating hormone in the serum the examined patients were distributed into two groups of 25 patients with the compensated and 25 with decompensated course of hypothyroidism. The control group consisted of 30 patients with hypertension in which the pathology of the thyroid gland was excluded. The comparison of the main parameters of the echocardiography study of the myocardium has been performed depending on hypothyroidism compensation. Assessment of parameters of transmitral diastolic blood flow has been performed. A regression analysis has been conducted to detect the relation of clinical and past medical history factors and echocardiographic parameters with the development of diastolic dysfunction by E/A ratio. The values of central hemodynamics have been studied for evaluation of the contractile function of the myocardium. Results and discussion. According to the results of the echocardiography of both examined groups it has been found that the final systolic and stroke volume exceeded the parameters of the control group. The mean value of the left ventricle ejection fraction was statistically significantly lower than in the control group (p=0.004). The left ventricle myocardial mass in patients with hypothyroidism was statistically significantly greater than in the control group. It was proved that in patients, who were diagnosed with decompensated hypothyroidism, the mean value of the left atrium size to growth by the degree of 2.7 was statistically significantly higher than in the control group (p=0.01), whereas the average value of the ratio of the size of the left atrium to the surface area of the body had no statistically significant differences between the groups. It has been found that in both groups the proportion of patients with diastolic dysfunction in which the E/A ratio was less than 1.0 was higher than in the control group (р=0.01 and p=0.03, respectively). The independent factors of diastolic dysfunction of the left ventricle in patients with hypertension in the presence of hypothyroidism have been found. Conclusions. In the presence of decompensated hypothyroidism in patients with arterial hypertension, both with obesity and with normal body mass index, left ventricular mass indexes were significantly higher in comparison with a control group. Regardless of the compensation of the thyroid state in patients with arterial hypertension, the ejection fraction was significantly lower. According to regression analysis, independent factors for the development of diastolic dysfunction in patients with arterial hypertension and hypothyroidism with a body mass index ≥ 30 kg/m2 is the index of mass of the left ventricular myocardium, determined by the degree of 2.7, the level of total cholesterol to statistical significance – the level of office systolic blood pressure and the duration of hormone replacement therapy for hypothyroidism; with body mass index < 30 kg/m2 – age and left atrial index, determined by body surface area. For patients with arterial hypertension and reduced thyroid gland function, violation of the left ventricular myocardial relaxation is typical as evidenced by a higher proportion of patients with a decrease in E/A to less than 0.8 in these patients.

ABSTRACTAimLongitudinal global strain (LGS) is reduced in obese patients with normal ejection fraction of the left ventricle. TAPSE/PAPS ratio, recently described, may be a step forward a more efficient RV function evaluation.There are still few publications in the application of these methods in pediatric patients.MethodsThis case-control study compared 104 children aged 5-18 years between October 2017 and February 2019, 52 obese children with body mass index (BMI) > +2 SD, and 52 matched controls.They were screened for other cardiovascular risk factors like insulin resistance or hypercholesterolemia. A complete echocardiography including standard and functional parameters was performed.ResultsWe found that obese children presented poor systolic function (LGS −15,90 ± 3,84 %) in comparison with non-obese children (−19,44 ± 5,75 %, p=0,001). LGS correlated positively with body mass index (BMI).Standard echocardiography also revealed cardiomegaly and hypertrophy.TAPSE/PASP ratio correlated negatively with triglycerides levels (β −0,402, p=0,014). Diastolic function was poor in those with HOMA-IR (β −0,375, p=0,016) and hypertriglyceridemia (β −0,375 p=0,024).ConclusionWe think that is necessary to perform a standarised cardiovascular evaluation in obese children for early identification of subclinical dysfunction especially in those with insulin resistance and dyslipidemia

Baseline Bmi

Introduction: Obesity is a risk factor for left ventricular dysfunction and incident heart failure. We hypothesized that baseline body mass index (BMI) and trajectories in weight change through young adulthood are associated with abnormal cardiac mechanics in middle age. Methods: We examined 2,735 participants from the Coronary Artery Risk Development in Young Adults (CARDIA) study. BMI was calculated at exam years 0, 2, 5, 7, 10, 15, 20, 25. 2D echo was performed with speckle-tracking analysis. Left ventricular ejection fraction (LVEF) and global longitudinal, circumferential, and radial strain (GLS, GCS, GRS, respectively) were measured at y25. Group-based modeling with latent class analysis (PROC TRAJ) was used to identify trajectories in relative changes in BMI (% change in BMI from baseline at each exam). Linear regression examined associations between baseline BMI and trajectory of BMI change and absolute GLS, GCS, and GRS at y25 adjusting for demographics, risk factors, and echo parameters. Results: Mean age at baseline was 25±4 years. Baseline BMI at y0 was significantly associated with mean GLS at y25 (p=0.01), but not GRS or GCS. We identified 4 distinct trajectories of relative BMI change: stable weight (36% of sample), mild increase (40%), moderate increase (18%), and major increase (6%) in weight (Figure). At y25, there was no difference in LVEF across the 4 BMI trajectory groups (P=NS). After adjustment for clinical variables and baseline BMI, absolute GLS was lower in groups with BMI increases (overall P<0.001). GRS and GCS were not significantly different between the groups. Conclusion: In conclusion, baseline BMI and increases in BMI during young adulthood are significantly associated with the presence of subclinical cardiac dysfunction in middle age despite normal EF. This novel characterization of BMI trajectories across young adulthood may assist in improving understanding of the impact of weight gain and obesity on cardiac dysfunction.
