Adherence to optimal heart rate control in heart failure with reduced ejection fraction: insight from a survey of heart rate in heart failure in Sweden (HR-HF study).

INTRODUCTION: Despite that heart rate (HR) control is one of the guideline-recommended treatment goals for heart failure (HF) patients, implementation has been painstakingly slow. Therefore, it would be important to identify patients who have not yet achieved their target heart rates and assess possible underlying reasons as to why the target rates are not met. MATERIALS AND METHODS: The survey of HR in patients with HF in Sweden (HR-HF survey) is an investigator-initiated, prospective, multicenter, observational longitudinal study designed to investigate the state of the art in the control of HR in HF and to explore potential underlying mechanisms for suboptimal HR control with focus on awareness of and adherence to guidelines for HR control among physicians who focus on the contributing role of beta-blockers (BBs). RESULTS: In 734 HF patients the mean HR was 68 ± 12 beats per minute (bpm) (37.2% of the patients had a HR >70 bpm). Patients with HF with reduced ejection fraction (HFrEF) (n = 425) had the highest HR (70 ± 13 bpm, with 42% >70 bpm), followed by HF with preserved ejection fraction and HF with mid-range ejection fraction. Atrial fibrillation, irrespective of HF type, had higher HR than sinus rhythm. A similar pattern was observed with BB treatment. Moreover, non-achievement of the recommended target HR (<70 bpm) in HFrEF and sinus rhythm was unrelated to age, sex, cardiovascular risk factors, cardiovascular diseases, and comorbidities, but was related to EF and the clinical decision of the physician. Approximately 50% of the physicians considered a HR of >70 bpm optimal and an equal number considered a HR of >70 bpm too high, but without recommending further action. Furthermore, suboptimal HR control cannot be attributed to the use of BBs because there was neither a difference in use of BBs nor an interaction with BBs for HR >70 bpm compared with HR <70 bpm. CONCLUSION: Suboptimal control of HR was noted in HFrEF with sinus rhythm, which appeared to be attributable to physician decision making rather than to the use of BBs. Therefore, our results underline the need for greater attention to HR control in patients with HFrEF and sinus rhythm and thus a potential for improved HF care.

Rehabilitation activities, out-patient visits and employment in patients and partners the first year after ICU: a descriptive study.

OBJECTIVES: To describe the influence of critical illness on patients and their partners in relation to rehabilitation, healthcare consumption and employment during the first year after Intensive Care Unit discharge. DESIGN: Longitudinal, observational and descriptive. SETTING: Five Danish Intensive Care Units. METHODS: Data were collected from hospital charts, population registers and interviews with 18 patients and their partners at 3 and 12 months after intensive care discharge. Descriptive statistical analysis was performed. RESULTS: Post-discharge inpatient rehabilitation was median (range) 52 (15-174) days (n=10). Community-based training was 12 (3-34) weeks (n=15). Neuropsychological rehabilitation following brain damage was 13-20 weeks (n=3). Number of out-patient visits 1 year before and 1 year after were mean 3 versus 8, and General Practitioner visits were 12 versus 18. Three patients resumed work at pre-hospitalisation employment rates after 12 months. After the patients' stay in intensive care, partners' mean full-time sick leave was 17 (range 0-124) days and 21 (range 0-106) days part time. Partners often had long commutes. CONCLUSION: Most patients had comprehensive recovery needs requiring months of rehabilitation. Some partners needed extensive sick leave. The study reveals the human cost of critical illness and intensive care for patients and partners in the Danish welfare system.

Struggling for independence: a grounded theory study on convalescence of ICU survivors 12 months post ICU discharge.

OBJECTIVES: To explore and explain the challenges, concerns, and coping modalities in ICU-survivors living with a partner or spouse during the first 12 months post ICU discharge. DESIGN: Qualitative, longitudinal grounded theory study. SETTINGS: Five ICUs in Denmark, four general, one neurosurgical. METHODS: Thirty-five interviews with patients and their partners at three and 12 months post ICU discharge plus two group interviews with patients only and two with partners only. FINDINGS: The ICU survivors struggled for independence and focussed chiefly on 'recovering physical strength', 'regaining functional capacity', and 'resuming domestic roles'. The first year of recovery evolved in three phases characterised by training, perseverance and continued hope for recovery. The ICU survivors did not seem to worry about traumatic experiences. Rather, their focus was on a wide range of other aspects of getting well. CONCLUSION: The study offers new insight into post-ICU convalescence emphasising patients' motivation for training to recover. The findings may contribute to defining the best supportive measures and timing of rehabilitation interventions in ICU and post ICU that may help ICU-survivors in their struggle for independence throughout recovery.

Patients' experiences of intervention trials on the treatment of myocardial infarction: is it time to adjust the informed consent procedure to the patient's capacity?

OBJECTIVE: To investigate how patients included in trials on treatment in the early phase of acute myocardial infarction experience the consent procedure. DESIGN: A combined qualitative and quantitative interview concerning the patients' knowledge of the trial, their feelings about being asked to participate, and their attitudes towards the consent procedure. SETTING: Tertiary referral centre. PATIENTS: 31 patients who had given written informed consent for their participation in randomised intervention trials of acute myocardial infarction. RESULTS: The patients interviewed had only fragmentary knowledge about the trial they were involved in. Most considered that reading and signing a consent form was an unwanted or unnecessary procedure. Instead, they would have preferred to have been given concise verbal information about the study. Most were willing to allow a physician to decide for them in the event of their being too ill to be asked about their participation. CONCLUSIONS: Patients who are asked to participate in intervention trials in the early phase of acute myocardial infarction often appear to lack sufficient knowledge to reach an autonomous choice. There were problems and disadvantages associated with the process of obtaining written informed consent in this particular situation, especially regarding the need for the patient to sign a consent form during the acute phase of the disease.

Should cardiopulmonary resuscitation be performed on patients with heart failure? The role of the patient in the decision-making process.

OBJECTIVES: There is an ongoing debate about patients' involvement in the decision of whether or not to start, cardiopulmonary resuscitation (CPR) in the case of cardiac arrest. The objective here is to analyse on what grounds patients with heart failure, who run a relatively high risk of suffering cardiac arrest, form their attitudes towards CPR and to what extent they want to be involved in making decisions concerning CPR. DESIGN: This study employs a combined qualitative and quantitative interview concerning patients' knowledge about CPR, their experiences and preferences regarding involvement in making decisions concerning CPR, and their willingness to undergo CPR. SETTING: The study was performed at the Department of Cardiology, Sahlgrens University Hospital, Gothenburg. SUBJECTS: The subjects involved were 40 patients with various stages of chronic heart failure. RESULTS: Many of the interviewees lacked fundamental knowledge of CPR. The majority of the patients opted for CPR no matter how small their chances of survival were. The issue had not earlier engaged their thoughts, even less been discussed with physicians. The patients relied on the physician's ability to judge if CPR was to be regarded as a potentially beneficial intervention or as an unmotivated one. Nevertheless, the patients welcomed the opportunity to take part in the decision-making process. CONCLUSION: In order to make ethically justified decisions, physicians should consider bringing up the question of CPR with patients suffering from heart failure at the point in time where the progressive disease gives rise to more severe symptoms, corresponding to NYHA classes IIIb-IV. In earlier stages of the disease, one can assume that the patient will opt for CPR unless he or she demonstrates a negative attitude towards life.

[Improved survival after in-hospital cardiac arrest]. / Förbättrad överlevnad efter hjärtstopp på sjukhus.

Internationally, survival among patients suffering in-hospital cardiac arrest is relatively low and unchanged at about 15%. Our experience at Sahlgrenska Hospital in Göteborg indicates a higher rate. We found survival to be related to the type of arrhythmia initially encountered, the highest rate having been observed among patients in ventricular fibrillation. We also found survival among patients suffering cardiac arrest to be higher in monitored as opposed to non-monitored wards. Whether the improved survival rate observed at Sahlgrenska as compared with international observations among patients suffering cardiac arrest is due to improvements in the organization or to patient selection is not clear. In order to achieve a higher survival rate after in-hospital cardiac arrest an efficient organization in which health care providers are given regular training and feed back is most likely of the utmost importance.

Ambulatory blood pressure: a predictor of left ventricular mass and future blood pressure in subjects predisposed for hypertension.

Twenty-four-hour ambulatory blood pressure (SpaceLab 5200) and a single laboratory blood pressure were measured in a population-derived sample of normotensive men (mean age 36 years) with (n = 13) or without (n = 16) a positive family history of hypertension. The aim was to determine whether ambulatory monitoring was a better predictor than clinical measurements for echocardiographic derived indices of left ventricular mass and for future blood pressure. At the initial examination ambulatory blood pressure could discriminate between the groups, showing significant differences that were not evident from the clinical blood pressure measurement. After 5 years the blood pressure had increased in the group with a family predisposition for hypertension but only one subject had overt hypertension. The correlation between the average day-time blood pressure and the clinical blood pressure at follow-up was only marginally better than the correlation for the initial clinical blood pressure. In contrast to the clinical blood pressure, both day-time and night-time blood pressure averages were significantly correlated to left ventricular mass at the initial examination. It is concluded that in still normotensive subjects, ambulatory monitoring is a better predictor than clinical measurements for left ventricular mass but not for future blood pressure.
