Background — It is well established that a depressed baroreflex sensitivity may adversely influence the prognosis in patients with chronic heart failure (CHF) and in those with previous myocardial infarction. Methods and Results — We tested whether a slow breathing rate (6 breaths/min) could modify the baroreflex sensitivity in 81 patients with stable (2 weeks) CHF (age, 58±1 years; NYHA classes I [6 patients], II [33], III [27], and IV [15]) and in 21 controls. Slow breathing induced highly significant increases in baroreflex sensitivity, both in controls (from 9.4±0.7 to 13.8±1.0 ms/mm Hg, P <0.0025) and in CHF patients (from 5.0±0.3 to 6.1±0.5 ms/mm Hg, P <0.0025), which correlated with the value obtained during spontaneous breathing ( r =+0.202, P =0.047). In addition, systolic and diastolic blood pressure decreased in CHF patients (systolic, from 117±3 to 110±4 mm Hg, P =0.009; diastolic, from 62±1 to 59±1 mm Hg, P =0.02). Conclusions — These data suggest that in patients with CHF, slow breathing, in addition to improving oxygen saturation and exercise tolerance as has been previously shown, may be beneficial by increasing baroreflex sensitivity.
IntroductionQuality of life measures are useful when interventions or treatments are indicated for several reasons such as improvement of physical functioning, pain relief, to estimate the effectiveness of therapies or to predict mortality. The aim of the current study was to describe quality of life in patients with stable coronary artery disease, myocardial infarction and heart failure and to evaluate the relationship between depression and health-related quality of life.Material and methodsPatients after STEMI, with stable coronary artery disease, and heart failure (n = 332) completed the MacNew Heart Disease Health-related Quality of Life Questionnaire and the Hospital Anxiety and Depression Scale.ResultsPatients with myocardial infarction had significantly higher scores than patients with stable coronary artery disease or heart failure on the MacNew global scale (p < 0.001) and the physical (p < 0.001), emotional (p < 0.001) and social (p < 0.001) subscales. The anxiety scores were significantly higher in the group of patients with stable coronary artery disease than in patients with myocardial infarction (p < 0.05). The depression scores were significantly higher in patients with heart failure (p < 0.01).ConclusionsIn patients with stable CAD, anxiety correlated mainly with symptoms, i.e. angina, than with the history of MI. Patients with symptoms of angina react to the illness with anxiety more than depression, whereas patients with heart failure with dyspnea react to the illness with depressive symptoms more than anxiety. In patients after MI and with stable CAD, cognitive-behavioral techniques could be useful to quickly reduce the level of anxiety, while patients with heart failure require long-term support therapy to reduce the risk of depressive symptoms.
Background. The prognostic value of cardiopulmonary exercise testing (CPET) is known, but the predictive value of 6MWT in patients with heart failure (HF) and patients undergoing coronary artery bypass grafting (CABG) is not established yet. Objective. We conducted a systematic review exploring the prognostic value of 6MWT in HF patients undergoing cardiac surgery. The aim was to find out whether the change in the distance walked during follow-up visits was associated with prognosis. Data Source. We searched “PubMed” from January 1990 to December 2012 for any review articles or experimental studies investigating the prognostic value of 6MWT in HF patients and patients undergoing cardiac surgery. Results. 53 studies were included in the review, and they explored the role of 6MWT in cardiology, cardiac surgery, and rehabilitation. The results did not show the relation between the six-minute walk distance and adverse events after CABG. The predictive power of the distance walked for death in HF patients undergoing cardiac surgery was not found. It is not yet proved if the change in the six-minute walk distance is associated with prognosis. The predictive power of the six-minute walk distance for death in HF patients undergoing cardiac surgery remains unclear.
Aims To assess the proportion of patients with heart failure and reduced ejection fraction (HFrEF) who are eligible for sacubitril/valsartan (LCZ696) based on the European Medicines Agency/Food and Drug Administration (EMA/FDA) label, the PARADIGM‐HF trial and the 2016 ESC guidelines, and the association between eligibility and outcomes. Methods and results Outpatients with HFrEF in the ESC‐EORP‐HFA Long‐Term Heart Failure (HF‐LT) Registry between March 2011 and November 2013 were considered. Criteria for LCZ696 based on EMA/FDA label, PARADIGM‐HF and ESC guidelines were applied. Of 5443 patients, 2197 and 2373 had complete information for trial and guideline eligibility assessment, and 84%, 12% and 12% met EMA/FDA label, PARADIGM‐HF and guideline criteria, respectively. Absent PARADIGM‐HF criteria were low natriuretic peptides (21%), hyperkalemia (4%), hypotension (7%) and sub‐optimal pharmacotherapy (74%); absent Guidelines criteria were LVEF>35% (23%), insufficient NP levels (30%) and sub‐optimal pharmacotherapy (82%); absent label criteria were absence of symptoms (New York Heart Association class I). When a daily requirement of ACEi/ARB ≥ 10 mg enalapril (instead of ≥ 20 mg) was used, eligibility rose from 12% to 28% based on both PARADIGM‐HF and guidelines. One‐year heart failure hospitalization was higher (12% and 17% vs. 12%) and all‐cause mortality lower (5.3% and 6.5% vs. 7.7%) in registry eligible patients compared to the enalapril arm of PARADIGM‐HF. Conclusions Among outpatients with HFrEF in the ESC‐EORP‐HFA HF‐LT Registry, 84% met label criteria, while only 12% and 28% met PARADIGM‐HF and guideline criteria for LCZ696 if requiring ≥ 20 mg and ≥ 10 mg enalapril, respectively. Registry patients eligible for LCZ696 had greater heart failure hospitalization but lower mortality rates than the PARADIGM‐HF enalapril group.
Background/Objective: Diseases of the cardiovascular system and depression are common, and they often coexist, significantly deteriorating the quality of life. Another factor influencing vital functions is impairment of cognitive functions occurring in patients with heart failure (HF). Deficits of different degrees of severity have been observed within a variety of cognitive domains. Cognitive deficits, which may impair daily functioning, hinder adaptation to the disease and worsen prognosis, are also observed in depression. The aim of this study was to assess the relationship between the quality of life, the severity of depressive disorders and disorders of certain executive functions, and memory in patients with severe, stable heart failure. Method: The study group consisted of 50 patients with stable, severe heart failure and 50 appropriately selected patients with coronary heart disease, without heart failure. Results: The results of cognitive tests are significantly lower in the HF group than in the control group. In the HF group, a significantly lower quality of life, as well as a higher result in the BDI-II test, was observed. No influence of cognitive disorders on the reduction in the quality of life was demonstrated. The factor that significantly affects the quality of life is the intensification of depression symptoms. Conclusions: The factor that significantly affects the quality of life is the intensification of depression symptoms.
SLOWB training improves cardiorespiratory capacity and appears to slow the progression of HFrEF. Further long-term outcome studies are required to confirm the benefits of paced breathing in HFrEF.
The effectiveness of hypertension treatment remains low in many developed countries. The aim of our study was to evaluate the treatment effectiveness in hypertensives treated by general practitioners (GPs) in Poland. Twenty thousand three hundred and five hypertensive patients (mean age 60.1 +/- 12.0 years, 9918 women, 10 387 men), pharmacologically treated by 677 GPs in Poland, were investigated. Blood pressure (BP) in every patient was measured twice, within approximately a 5-min interval, in a seated position, using a mercury sphygmomanometer, after a rest of at least 10 min. Mean blood pressure from both measurements was used for further analysis. Measurements were carried out by a GP in the office. Every physician investigated 30 consecutive hypertensive patients. Of the investigated hypertensive patients treated, 8.3% had systolic blood pressure (SBP) < 140 mmHg and diastolic blood pressure (DBP) < 90 mmHg (7.8% in women, 8.8% in men respectively; p > 0.05). Mean SBP in the investigated group was 161.9 +/- 20.4 mmHg, 162.7 +/- 20.8 mmHg in women and 161.1 +/- 20.1 mmHg in men, respectively; p < 0.05. Mean DBP was 95.4 +/- 11.0 mmHg. The difference between mean DBP in women (95.3 +/- 11.0 mmHg) and men (95.5 +/- 11.1 mmHg) was not significant, p > 0.05. Mean pulse pressure (PP) for the whole group was 66.5 +/- 16.3 mmHg. In this cohort, 26.7% of patients were treated with one, 37.6% with two, 26.7% with three, 8.2% with four and 0.8% with five antihypertensive drugs. Mean number of antihypertensive drugs prescribed for one hypertensive patient was 2.2 +/- 1.0. Effectiveness of hypertension treatment by GPs in Poland remained unsatisfactory despite frequent implementation of combined antihypertensive drug therapy.
