Significant left ventricular outflow tract gradient reduction with exercise capacity improvement was achieved in the majority of patients treated with non-surgical myocardial reduction. We recommend this method as an alternative to surgery for symptomatic patients with hypertrophic obstructive cardiomyopathy.
The aim of our study was to evaluate renal resistive index (RI) value in never treated hypertensive patients in relation to ambulatory blood pressure measurement (ABPM) values and early target organ damage. The study included 318 subjects: 223 patients with never treated essential hypertension (mean age 37.1 years) and 95 normotensive healthy subjects (mean age 37.9 years). ABPM, echocardiography and carotid and renal arteries duplex color Doppler examinations were performed. RI values in patients with never treated essential hypertension were no different from the normotensive control group (0.59 +/- 0.05 vs 0.59 +/- 0.05; NS). In the untreated patients RI correlated significantly with 24-h pulse pressure (r=0.234; p<0.01) and ambulatory arterial stiffness index (AASI) values (r=0.274; p<0.001), intima-media thickness (IMT) (r=0.249; p<0.001), E'/A' (rho= -0.279; p<0.001) and relative wall thickness (RWT; r=0.185; p<0.01). In the multivariate stepwise analysis, RI values correlated independently with carotid IMT (beta=0.272; p=0.020) and 24-h AASI values (beta=0.305; p=0.009). In normotensive healthy controls, significant independent correlation between RI and carotid IMT and 24-h AASI values were also found. Our study may indicate limited value of RI in differentiating patients with uncomplicated hypertension with healthy controls. Renal resistive values were independently correlated with carotid IMT and AASI. These may suggest that renal vascular resistance is related to two markers for cardiovascular events both in the hypertensive and normotensive subjects.
The COVID-19 pandemic has affected the physical and mental health of people around the world. This may be particularly true for patients with life-threatening diseases. We analyzed the level of fear of COVID-19 (FCV-19S), the prevalence of anxiety (HADS-A) and depression (HADS-D) in pulmonary arterial and chronic thromboembolic pulmonary hypertension (PAH and CTEPH) patients during the COVID-19 pandemic. In this multicenter prospective study, 223 patients (63% females, 66% PAH) with age range 18–90 years were included. The fear of COVID-19 was high, at a mean level of 18.9 ± 7.4 points. Anxiety (HADS-A ≥ 8 points) was diagnosed in 32% of all patients, depression (HADS-D ≥ 8 points) in 21%, and anxiety or depression in 38%. FCV-19S was higher in woman and in elderly people (p = 0.02; p = 0.02, respectively). In the multivariate analysis, FCV-19S higher than the median increased the odds ratio of anxiety, but not of depression (R 6.4 (95%CI 2.0–20.0), p = 0.002; OR 1.9 (0.9–3.9), p = 0.06, respectively). History of COVID-19 increased risk of both HADS-A and HADS-D. Patients with PAH and CTEPH, especially woman over 65 years and those who had been infected with COVID-19, may need additional psychological support due to fear of COVID-19, anxiety or depression.
We addressed a question if there is a relationship between severity of newly diagnosed obstructive sleep apnea (OSA) and markers of cardiovascular alterations in middle-aged untreated hypertensive patients. In 121 consecutive patients with never-treated essential hypertension (mean age 35.9±10.1 years; 97 men and 24 women) evaluation of office and ambulatory blood pressure (BP) measurements, metabolic syndrome (MS) components and markers of alterations in cardiovascular system including left ventricular structure and function, carotid artery wall intima-media thickness (cIMT) and urinary albumin excretion (UAE) was performed. OSA was classified as mild (apnea/hypopnea index (AHI) 5-15 events h(-1)) or moderate-to-severe (AHI >15 events h(-1)). Mild and moderate-to-severe OSA were diagnosed in 30% and 20% of patients, respectively. No differences in nighttime BP levels and decline between patients with and without OSA were observed. The patients with moderate-to-severe OSA were characterized by higher cIMT (0.74±0.16 vs. 0.60±0.15 mm; P=0.001), UAE (14.5±6.9 vs. 10.0±8.0 mg 24 h(-1); P=0.014), relative wall thickness (0.42±0.05 vs. 0.39±0.05; P=0.023) and by a higher degree of diastolic dysfunction (E'-wave velocity 11.4±3.2 vs. 15.5±3.8 m s(-1); P<0.001) as compared with the patients without OSA. In multivariate analysis, AHI independently of BP and MS components correlated with UAE, relative wall thickness and E'-wave velocity. In the middle-aged never-treated hypertensive patients, moderate-to-severe OSA correlates with markers of cardiovascular alterations independently of BP levels and MS components.
The incidence of COVID-19 infection in patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) is similar to that in the general population, but the mortality rate is much higher. COVID-19 vaccination is strongly recommended for PAH/CTEPH patients. The aim of our cross-sectional study was to identify reasons why PAH/CTEPH patients refused vaccination against COVID-19. Moreover, we assessed the safety profile of approved COVID-19 vaccines in PAH/CTEPH patients. We examined 261 patients (164 PAH patients and 97CTEPH patients) with a median age of 60 (18–92) years, 62% of which were female. Sixty-one patients (23%) refused to be vaccinated. The main reason for unwillingness to be vaccinated was anxiety about adverse events (AEs, 61%). Age and fear of COVID-19 in the univariate analysis and age ≥60 years in the multivariate regression analysis were factors that impacted willingness to be vaccinated (OR = 2.5; p = 0.005). AEs were reported in 61% of vaccinated patients after the first dose and in 40.5% after the second dose (p = 0.01). The most common reported AEs were pain at the injection site (54.5%), fever (22%), fatigue (21%), myalgia (10.5%), and headache (10%). A lower percentage of AEs was reported in older patients (OR = 0.3; p = 0.001). The COVID-19 vaccines are safe for PAH/CTEPH patients. The results obtained in this study may encourage patients of these rare but severe cardio-pulmonary diseases to get vaccinated against COVID-19.
