Respiratory sleep disorders in patients with congestive heart failure.

ABSTRACT: Respiratory sleep disorders (RSD) occur in about 40-50% of patients with symptomatic congestive heart failure (CHF). Obstructive sleep apnea (OSA) is considered a cause of CHF, whereas central sleep apnea (CSA) is considered a response to heart failure, perhaps even compensatory. In the setting of heart failure, continuous positive airway pressure (CPAP) has a definite role in treating OSA with improvements in cardiac parameters expected. However in CSA, CPAP is an adjunctive therapy to other standard therapies directed towards the heart failure (pharmacological, device and surgical options). Whether adaptive servo controlled ventilatory support, a variant of CPAP, is beneficial is yet to be proven. Supplemental oxygen therapy should be used with caution in heart failure, in particular, by avoiding hyperoxia as indicated by SpO2 values >95%.

Sleep fragmentation and incidence of congestive heart failure: the Sleep Heart Health Study.

Project description:Study objectivesSleep fragmentation (SF) has been reported to be associated with cardiovascular risk. The aim of this study was to explore the relationship between SF and congestive heart failure (CHF).MethodsA total of 4,887 participants (2,256 males and 2,631 females; mean age of 63.6 ± 11.0 years) from the Sleep Heart Health Study were included in this study. Incident CHF was defined as the first occurrence of CHF between baseline in-home polysomnography (PSG) and the end of follow-up. Objective assessments for SF, including sleep fragmentation index (SFI), arousal index (ArI), sleep efficiency (SE), and wake after sleep onset (WASO), were determined based on in-home PSG records. Multivariate Cox regression analysis was used to investigate the relationship between SF and incident CHF.ResultsDuring an average of 10 years of follow-up, 543 participants with CHF (11.1%) were observed. Individuals with CHF had a significantly higher SFI, total ArI, and WASO and a lower SE than controls. After multivariate Cox regression analysis, SE (odds ratio [OR], 0.967; 95% confidence interval [CI], 0.955-0.978; P < .001), WASO (OR, 1.009; 95% CI, 1.006-1.012; P < .001), SFI (OR, 1.046; 95% CI, 1.007-1.086; P = .021), and total ArI (OR, 1.018; 95% CI, 1.000-1.035; P = .044) were found to be associated with the incidence of CHF in participants without hypertension.ConclusionsObjectively measured SF was associated with the incidence of CHF. The role of SFI, total ArI, SE, and WASO deserves further investigation.Clinical trial registrationRegistry: ClinicalTrials.gov; Name: Sleep Heart Health Study (SHHS) Data Coordinating Center (SHHS); URL: https://clinicaltrials.gov/ct2/show/NCT00005275; Identifier: NCT00005275.CitationYan B, Wu Y, Fan X, Lu Q, Ma X, Bai L.

Control and Congestive Heart Failure

Project description:Congestive heart failure was done by artificial myocardial infarction. After extracting total RNA from control and infarcted ventricles with Triazol, messenger RNA was isolated with Qiagen mRNA isolation kit. About 1.5ug poly A+ RNA was taken for probe preparation. Probe was labeled with Alexa Fluor 546 and 657. Labeled probes were hybridized with Qiagen rat unigene oligo library. After 2 low and 1 high stringency washes Prolong Antifade was added to the slides to prevent bleaching effect. The data ratio was normalized using a location and intensity dependent Lowess formula.

Sleep Timing May Predict Congestive Heart Failure: A Community-Based Cohort Study.

Project description:Background Previous studies have suggested that sleep timing is associated with cardiovascular risk factors. However, there is no evidence on the relationship between sleep timing and congestive heart failure (CHF). We aimed to examine this relationship in this study. Methods and Results We recruited 4765 participants (2207 men; mean age, 63.6±11.0 years) from the SHHS (Sleep Heart Health Study) database in this multicenter prospective cohort study. Follow-up was conducted until the first CHF diagnosis between baseline and the final censoring date. Sleep timing (bedtimes and wake-up times on weekdays and weekends) was based on a self-reported questionnaire. Cox proportional hazard models were constructed to investigate the association between sleep timing and CHF. During the mean follow-up period of 11 years, 519 cases of CHF (10.9%) were reported. The multivariable Cox proportional hazards models revealed that participants with weekday bedtimes >12:00 am (hazard ratio [HR], 1.56; 95% CI, 1.15-2.11; P=0.004) and from 11:01 pm to 12:00 am (HR, 1.25; 95% CI, 1.00-1.56; P=0.047) had an increased risk of CHF compared with those with bedtimes from 10:01 pm to 11:00 pm. After stratified analysis, the association was intensified in participants with a self-reported sleep duration of 6 to 8 hours. Furthermore, wake-up times >8:00 am on weekdays (HR, 1.53; 95% CI, 1.07-2.17; P=0.018) were associated with a higher risk of incident CHF than wake-up times ≤6:00 am. Conclusions Delayed bedtimes (>11:00 pm) and wake-up times (>8:00 am) on weekdays were associated with an increased risk of CHF.

Incidental Congestive Heart Failure in Patients With Aldosterone-Producing Adenomas.

Project description:Background Previous studies show that patients with primary aldosteronism are associated with higher risk of congestive heart failure (CHF). However, the effect of target treatment to the incidental CHF has not been elucidated. We aimed to investigate the risk of new-onset CHF in patients with aldosterone-producing adenomas (APAs) and explore the effect of adrenalectomy on new onset of CHF. Methods and Results From 1997 to 2009, 688 APA were identified and matched with essential hypertension controls. The risks of developing incidental CHF (hazard ratio, 0.49; 95% CI, 0.31-0.75; P=0.001) and mortality (hazard ratio, 0.29; 95% CI, 0.20-0.44; P<0.001) were significantly lower in the APA group after targeted treatment. A total of 605 patients with APAs who underwent adrenalectomy lowered the risks of CHF (subdistribution hazard ratio, 0.55; 95% CI, 0.34-0.90; P=0.017) and mortality (adjusted hazard ratio, 0.27; 95% CI, 0.16-0.44; P<0.001) compared with essential hypertension controls. Conclusions In conclusion, for patients with APAs, adrenalectomy can be associated with lower risk of incidental CHF and all-cause mortality in a long-term follow-up.

Hypertrophic remodelling of retinal arterioles in patients with congestive heart failure.

Project description:AimsAnalysis of microvascular parameters in the retinal circulation-known to reflect those in the systemic circulation-allows us to differentiate between eutrophic and hypertrophic remodelling of small arteries. This study aimed to examine microvascular changes in patients with congestive heart failure (CHF) and reduced as well as mid-range ejection fraction.Methods and resultsForty subjects with CHF underwent measurement of retinal capillary flow (RCF), wall-to-lumen ratio (WLR), vessel and lumen diameter, wall thickness, and wall cross-sectional area (WCSA) of retinal arterioles of the right eye by scanning laser Doppler flowmetry (SLDF). Applying a matched pair approach, we compared this group with reference values of age-matched controls from a random sample in the population of Pilsen, Czech Republic. There was no significant difference in RCF and WLR between the groups (RCF: P = 0.513; WLR: P = 0.106). In contrast, wall thickness and WCSA, indicators of hypertrophic remodelling, were higher in CHF subjects (WT: 15.0 ± 4.2 vs. 12.7 ± 4.2 μm, P = 0.021; WCSA: 4437.6 ± 1314.5 vs. 3615.9 ± 1567.8 μm2 , P = 0.014). Similarly, vessel (109.4 ± 11.1 vs. 100.5 ± 14.4 μm, P = 0.002) and lumen diameter (79.0 ± 7.9 vs. 75.2 ± 8.5 μm, P = 0.009) were increased in CHF.ConclusionsIn CHF subjects, we observed hypertrophic remodelling of retinal arterioles indicative of similar changes of small resistance arteries in the systemic circulation. Microvascular structure and function assessed by SLDF may thereby represent a useful, non-invasive method for monitoring of microvascular damage in patients with CHF and may offer innovative treatment targets for new CHF therapies.

Cardiopulmonary ultrasound correlates of pleural effusions in patients with congestive heart failure.

Project description:BackgroundPleural effusions are common in patients with congestive heart failure. However, there is a need to assess systematically the correlation between effusion volume, extravascular lung water and echocardiographic parameters. We used combined cardiopulmonary ultrasound to evaluate the relationship between effusion volume, extravascular lung water, and echocardiographic parameters in patients with congestive heart failure.MethodsPatients who were hospitalized for congestive heart failure underwent combined cardiopulmonary ultrasound. A semiquantitative score of pleural effusions was derived by pulmonary ultrasound and extravascular lung water was estimated by ultrasound lung comets. The measurements were compared with echocardiographic and clinical results.ResultsAmong 168 patients (median age 66 years, 69.6% men), 102 (60.7%) had pleural effusions, 84.3% bilateral, 10.8% right-sided, and 4.9% left-sided. High pleural effusion scores were associated with high ultrasound lung comet scores (P < 0.0001). Compared with patients without pleural effusions, patients with pleural effusions were significantly older and had higher systolic pulmonary artery pressure (SPAP), NT-proBNP, New York Heart Association scale, larger left atrium, larger right ventricle, more severe mitral regurgitation, and worse left and right heart function. Adjusted for age, multiple logistic regression analysis showed that SPAP (OR 5.688, P = 0.006) and E/A (OR 3.941, P = 0.043) were the significant variables and risk factors associated with pleural effusions in heart failure.ConclusionFor patients with left heart failure, the degree of pleural effusions was associated with pulmonary congestion. Elevated SPAP and E/A were the main risk factors for the formation of pleural effusions in patients with congestive heart failure.

Sex differences in congestive markers in patients hospitalized for acute heart failure.

Project description:AimsWe sought to examine sex differences in congestion in patients hospitalized for acute heart failure (AHF). Understanding congestive patterns in women and men with AHF may provide insights into sex differences in the presentation and prognosis of AHF patients.Methods and resultsIn a prospective, two-site study in adults hospitalized for AHF, four-zone lung ultrasound (LUS) was performed at the time of echocardiography at baseline (LUS1) and, in a subset, pre-discharge (LUS2). B-lines on LUS and echocardiographic images were analysed offline, blinded to clinical information and outcomes. Among 349 patients with LUS1 data (median age 74, 59% male, and 87% White), women had higher left ventricular ejection fraction (mean 43% vs. 36%, P < 0.001), higher tricuspid annular plane systolic excursion (mean 17 vs. 15 mm, P = 0.021), and higher measures of filling pressures (median E/e' 20 vs. 16, P < 0.001). B-line number on LUS1 (median 6 vs. 6, P = 0.69) and admission N-terminal pro-B-type natriuretic peptide levels (median 3932 vs. 3483 pg/mL, P = 0.77) were similar in women and men. In 121 patients with both LUS1 and LUS2 data, there was a similar and significant decrease in B-lines from baseline to discharge in both women and men. The risk of the composite 90 day outcome increased with higher B-line number on four-zone LUS2: unadjusted hazard ratio for each B-line tertile was 1.86 (95% confidence interval 1.08-3.20, P = 0.025) in women and 1.65 (95% confidence interval 1.03-2.64, P = 0.037) in men (interaction P = 0.72).ConclusionsAmong patients with AHF, echocardiographic markers differed between women and men at baseline, whereas B-line number on LUS did not. The dynamic changes in B-lines during a hospitalization for AHF were similar in women and men.
