Effect of implantable cardioverter-defibrillator in non-ischemic heart failure according to background medical therapy: Extended follow-up of the DANISH trial.

BACKGROUND: The Heart Failure Collaboratory (HFC) score integrates types and doses of guideline-directed pharmacotherapies for heart failure (HF) with reduced ejection fraction (HFrEF). We examined the effect of implantable cardioverter-defibrillator (ICD) implantation according to modified HFC (mHFC) score in 1,116 patients with non-ischemic HFrEF from the Danish Study to Assess the Efficacy of ICDs in Patients with Non-ischemic Systolic HF on Mortality (DANISH). METHODS AND RESULTS: Patients were assigned scores for renin-angiotensin-system inhibitors, beta-blockers, and mineralocorticoid receptor antagonists (0: no use; 1: <50% of maximum dose; 2: ≥50% of maximum dose). The maximum score was 6, corresponding to ≥50% of maximum dose for all therapies. The median baseline mHFC score was 4, and the median follow-up was 9.5 years. Compared with mHFC score=3-4, mHFC score=1-2 was associated with a higher rate of all-cause death (mHFC=1-2: adjusted HR 1.67 [95%CI,1.23-2.28]; mHFC=3-4, reference; mHFC=5-6: adjusted HR 1.07 [95%CI,0.87-1.31]). ICD implantation did not reduce all-cause death compared with control (reference) (HR 0.89 [95%CI,0.74-1.08]) regardless of mHFC score (mHFC=1-2: HR 0.98 [95%CI,0.56-1.71]; mHFC=3-4: HR 0.89 [95%CI,0.66-1.20]; mHFC=5-6: HR 0.85 [95%CI,0.64-1.12]; Pinteraction, 0.65). Similarly, ICD implantation did not reduce cardiovascular death (HR 0.87 [95%CI,0.70-1.09]) regardless of mHFC score (Pinteraction, 0.59). The ICD group had a lower rate of sudden cardiovascular death (HR, 0.60 [95% CI,0.40-0.92]); this association was not modified by mHFC score (Pinteraction, 0.35). CONCLUSIONS: Lower mHFC scores were associated with higher rates of all-cause death. ICD implantation did not result in an overall survival benefit in patients with non-ischemic HFrEF regardless of mHFC score.

New York Heart Association functional class and implantable cardioverter-defibrillator in non-ischaemic heart failure with reduced ejection fraction: Extended follow-up of the DANISH trial.

AIMS: Current guidelines recommend implantable cardioverter-defibrillator (ICD) therapy in patients with heart failure, a left ventricular ejection fraction of ≤35%, and New York Heart Association (NYHA) class II-III. However, the evidence regarding the benefit of primary prevention ICD is less consistent in patients with NYHA class III. We investigated the long-term effects of primary prevention ICD implantation according to NYHA class in an extended follow-up study of the DANISH trial. METHODS AND RESULTS: The DANISH trial randomized 1116 patients with non-ischaemic heart failure with reduced ejection fraction (HFrEF) to ICD implantation or usual care. Outcomes were analysed according to NYHA class at baseline (NYHA class II and III/IV). The primary outcome was all-cause mortality. Of the 1116 patients randomized in the DANISH trial, 597 (53.5%) were in NYHA class II at baseline, 505 (45.3%) in NYHA class III, and 14 (1.3%) in NYHA class IV. During a median follow-up of 9.5 years, NYHA class III/IV, compared with NYHA class II, were associated with a greater long-term rate of all-cause mortality (hazard ratio [HR] 1.52, 95% confidence interval [CI] 1.20-1.93) and cardiovascular death (HR 1.95 [1.47-2.60]). ICD implantation, compared with usual care, did not reduce the long-term rate of all-cause mortality (all participants: HR 0.89 [95% CI 0.74-1.08]; NYHA class II: HR 0.85 [0.64-1.13]; NYHA class III/IV: HR 0.89 [0.69-1.14]; pinteraction = 0.78) or cardiovascular death (all participants: HR 0.87 [95% CI 0.70-1.09]; NYHA class II: HR 0.78 [0.54-1.12]; NYHA class III/IV: HR 0.89 [0.67-1.19]; pinteraction = 0.58), irrespective of NYHA class. Similarly, NYHA class did not modify the beneficial effects of ICD implantation on sudden cardiovascular death (all participants: HR 0.60 [95% CI 0.40-0.92]; NYHA class II: HR 0.73 [0.40-1.36]; NYHA class III/IV: HR 0.52 [0.29-0.94]; pinteraction = 0.39). CONCLUSIONS: In patients with non-ischaemic HFrEF, ICD implantation, compared with usual care, did not reduce the overall mortality rate, but it did reduce sudden cardiovascular death, regardless of baseline NYHA class.

The importance of nonobstructive plaque characteristics in symptomatic and asymptomatic coronary artery disease.

BACKGROUND: We examined obstructive and nonobstructive plaque volumes in populations with subclinical and clinically manifested coronary artery disease (CAD) using quantitative computed tomography (QCT). METHODS: 855 participants with CAD (274 asymptomatic individuals, 254 acute chest pain patients without acute coronary syndrome (ACS), and 327 patients with ACS) underwent QCT of proximal coronary segments to assess participant-level plaque volumes of dense calcium, fibrous, fibrofatty, and necrotic core tissue. RESULTS: Nonobstructive (<50% stenosis) plaque volumes were greater than obstructive plaque volumes, irrespective of population (all p<0.0001): Asymptomatic individuals (mean (95% CI)): 218 [190-250] vs. 16 [12-22] mm3; acute chest pain patients without ACS: 300 [263-341] vs. 51 [41-62] mm3; patients with ACS: 370 [332-412] vs. 159 [139-182] mm3. After multivariable adjustment, nonobstructive fibrous and fibrofatty tissue volumes were greater in acute chest pain patients without ACS compared to asymptomatic individuals (fibrous tissue: 122 [107-139] vs. 175 [155-197] mm3, p<0.01; fibrofatty tissue: 44 [38-50] vs. 71 [63-80] mm3, p<0.01. Necrotic core tissue was greater in ACS patients (29 [26-33] mm3) compared to both asymptomatic individuals (15 [13-18] mm3, p<0.0001) and acute chest pain patients without ACS (21 [18-24] mm3, p<0.05). Nonobstructive dense calcium volumes did not differ between the three populations: 29 [24-36], 29 [23-35], and 41 [34-48] mm3, p>0.3 respectively. CONCLUSION: Nonobstructive CAD was the predominant contributor to total atherosclerotic plaque volume in both subclinical and clinically manifested CAD. Nonobstructive fibrous, fibrofatty and necrotic core tissue volumes increased with worsening clinical presentation, while nonobstructive dense calcium tissue volumes did not.

Estimated Glomerular Filtration Rate and Implantable Cardioverter-Defibrillator in Nonischemic Systolic Heart Failure: Extended Follow-Up of DANISH.

BACKGROUND: Patients with heart failure and chronic kidney disease (CKD) may have an increased risk of death from causes competing with arrhythmic death, which could have implications for the efficacy of implantable cardioverter-defibrillators (ICDs). We examined the long-term effects of primary prophylactic ICD implantation, compared with usual care, according to baseline CKD status in an extended follow-up study of DANISH (Danish Study to Assess the Efficacy of ICDs in Patients With Nonischemic Systolic Heart Failure on Mortality). METHODS AND RESULTS: In the DANISH trial, 1116 patients with nonischemic heart failure with reduced ejection fraction were randomized to receive an ICD (N=556) or usual care (N=550). Outcomes were analyzed according to CKD status (estimated glomerular filtration rate ≥/<60 mL/min per 1.73 m2) at baseline. In total, 1113 patients had an available estimated glomerular filtration rate measurement at baseline (median estimated glomerular filtration rate 73 mL/min per 1.73 m2), and 316 (28%) had CKD. During a median follow-up of 9.5 years, ICD implantation, compared with usual care, did not reduce the rate of all-cause mortality (no CKD, HR, 0.82 [95% CI, 0.64-1.04]; CKD, HR, 1.02 [95% CI, 0.75-1.38]; Pinteraction=0.31) or cardiovascular death (no CKD, HR, 0.77 [95% CI, 0.58-1.03]; CKD, HR, 1.05 [95% CI, 0.73-1.51]; Pinteraction=0.20), irrespective of baseline CKD status. Similarly, baseline CKD status did not modify the beneficial effects of ICD implantation on sudden cardiovascular death (no CKD, HR, 0.57 [95% CI, 0.32-1.00]; CKD, HR, 0.65 [95% CI, 0.34-1.24]; Pinteraction=0.70). CONCLUSIONS: ICD implantation, compared with usual care, did not reduce the overall mortality rate, but it did reduce the rate of sudden cardiovascular death, regardless of baseline kidney function in patients with nonischemic heart failure with reduced ejection fraction.

Rifampicin reduces plasma concentration of linezolid in patients with infective endocarditis.

BACKGROUND: Linezolid in combination with rifampicin has been used in treatment of infective endocarditis especially for patients infected with staphylococci. OBJECTIVES: Because rifampicin has been reported to reduce the plasma concentration of linezolid, the present study aimed to characterize the population pharmacokinetics of linezolid for the purpose of quantifying an effect of rifampicin cotreatment. In addition, the possibility of compensation by dosage adjustments was evaluated. PATIENTS AND METHODS: Pharmacokinetic measurements were performed in 62 patients treated with linezolid for left-sided infective endocarditis in the Partial Oral Endocarditis Treatment (POET) trial. Fifteen patients were cotreated with rifampicin. A total of 437 linezolid plasma concentrations were obtained. The pharmacokinetic data were adequately described by a one-compartment model with first-order absorption and first-order elimination. RESULTS: We demonstrated a substantial increase of linezolid clearance by 150% (95% CI: 78%-251%), when combined with rifampicin. The final model was evaluated by goodness-of-fit plots showing an acceptable fit, and a visual predictive check validated the model. Model-based dosing simulations showed that rifampicin cotreatment decreased the PTA of linezolid from 94.3% to 34.9% and from 52.7% to 3.5% for MICs of 2 mg/L and 4 mg/L, respectively. CONCLUSIONS: A substantial interaction between linezolid and rifampicin was detected in patients with infective endocarditis, and the interaction was stronger than previously reported. Model-based simulations showed that increasing the linezolid dose might compensate without increasing the risk of adverse effects to the same degree.

Duration of Device-Based Fever Prevention after Cardiac Arrest.

BACKGROUND: Guidelines recommend active fever prevention for 72 hours after cardiac arrest. Data from randomized clinical trials of this intervention have been lacking. METHODS: We randomly assigned comatose patients who had been resuscitated after an out-of-hospital cardiac arrest of presumed cardiac cause to device-based temperature control targeting 36°C for 24 hours followed by targeting of 37°C for either 12 or 48 hours (for total intervention times of 36 and 72 hours, respectively) or until the patient regained consciousness. The primary outcome was a composite of death from any cause or hospital discharge with a Cerebral Performance Category of 3 or 4 (range, 1 to 5, with higher scores indicating more severe disability; a category of 3 or 4 indicates severe cerebral disability or coma) within 90 days after randomization. Secondary outcomes included death from any cause and the Montreal Cognitive Assessment score (range, 0 to 30, with higher scores indicating better cognitive ability) at 3 months. RESULTS: A total of 393 patients were randomly assigned to temperature control for 36 hours, and 396 patients were assigned to temperature control for 72 hours. At 90 days after randomization, a primary end-point event had occurred in 127 of 393 patients (32.3%) in the 36-hour group and in 133 of 396 patients (33.6%) in the 72-hour group (hazard ratio, 0.99; 95% confidence interval, 0.77 to 1.26; P = 0.70) and mortality was 29.5% in the 36-hour group and 30.3% in the 72-hour group. At 3 months, the median Montreal Cognitive Assessment score was 26 (interquartile range, 24 to 29) and 27 (interquartile range, 24 to 28), respectively. There was no significant between-group difference in the incidence of adverse events. CONCLUSIONS: Active device-based fever prevention for 36 or 72 hours after cardiac arrest did not result in significantly different percentages of patients dying or having severe disability or coma.

Rehospitalisations, repeated aortic surgery, and death in initial survivors of surgery for Stanford type A aortic dissection and the significance of age - a nationwide registry-based cohort study.

AIMS: Describe and compare incidences across age groups of rehospitalization, repeated aortic surgery, and death in patients who survived surgery and hospitalization for type A aortic dissection. METHODS AND RESULTS: From Danish nationwide registries, we identified patients hospitalized with Stanford type A aortic dissections (2006-2018). Survivors of hospitalization and surgery on the ascending aorta and/or aortic arch comprised the study population (n = 606, 36 (38.9%) <60 years old (group I), 194 (32.0%) 60-69 years old (group II), and 176 (29.1%) >69 years old (group III)). During the first year, 62.5% were re-hospitalized and 1.4% underwent repeated aortic surgery with no significant differences across age groups (P = 0.68 and P = 0.39, respectively). Further, 5.9% died (group I: 3.0%, group II: 8.3%, group III: 7.4%, P = 0.04). After 10 years, 8.0% had undergone repeated aortic surgery (group I: 11.5%, group II: 8.5%, group III: 1.6%, P = 0.04) and 10.2% (group I), 17.0% (group II), and 22.2% (group III) had died (P = 0.01). Using multivariable Cox regression analysis, we described long-term outcomes comparing age groups. No age differences were found in one-year outcomes, while age > 69 years compared with age < 60 years was associated with a lower rate of repeated aortic surgery [hazard ratio 0.17, 95% confidence interval (CI) 0.04-0.78] and a higher rate of all-cause mortality (hazard ratio 2.44, 95% CI 1.37-4.34) in the 10-year analyses. CONCLUSION: Rehospitalisations in the first year after discharge were common in all age groups, but survival was high. Repeated aortic surgery was significantly more common among younger than older patients.

Efficacy of Implantable Cardioverter Defibrillator in Nonischemic Systolic Heart Failure According to Sex: Extended Follow-Up Study of the DANISH Trial.

BACKGROUND: Men and women may respond differently to certain therapies for heart failure with reduced ejection fraction, including implantable cardioverter defibrillators (ICD). In an extended follow-up study of the DANISH trial (Danish Study to Assess the Efficacy of ICDs in Patients With Non-Ischemic Systolic Heart Failure on Mortality), adding 4 years of additional follow-up, we examined the effect of ICD implantation according to sex. METHODS: In the DANISH trial, 1116 patients with nonischemic systolic heart failure were randomized to receive an ICD (N=556) or usual clinical care (N=550). The primary outcome was all-cause mortality. RESULTS: Of the 1116 patients randomized in the DANISH trial, 307 (27.5%) were women. During a median follow-up of 9.5 years, women had a lower associated rate of all-cause mortality (hazard ratio [HR], 0.60 [95% CI, 0.47-0.78]) cardiovascular death (HR, 0.62 [95% CI, 0.46-0.84]), nonsudden cardiovascular death (HR, 0.59 [95% CI, 0.42-0.85]), and a numerically lower rate of sudden cardiovascular death (HR, 0.70 [95% CI, 0.40-1.25]), compared with men. Compared with usual clinical care, ICD implantation did not reduce the rate of all-cause mortality, irrespective of sex (men, HR, 0.85 [95% CI, 0.69-1.06]; women, HR, 0.98 [95% CI, 0.64-1.50]; Pinteraction=0.51). In addition, sex did not modify the effect of ICD implantation on sudden cardiovascular death (men, HR, 0.57 [95% CI, 0.36-0.92]; women, HR, 0.68 [95% CI, 0.26-1.77]; Pinteraction=0.76). CONCLUSIONS: In patients with nonischemic systolic heart failure, ICD implantation did not provide an overall survival benefit, but reduced sudden cardiovascular death, irrespective of sex.

Cardiovascular magnetic resonance characteristics and clinical outcomes of patients with ST-elevation myocardial infarction and no standard modifiable risk factors-A DANAMI-3 substudy.

Introduction: A higher 30-day mortality has been observed in patients with first-presentation ST elevation myocardial infarction (STEMI) who have no standard modifiable cardiovascular risk factors (SMuRFs), i. e., diabetes, hypertension, hyperlipidemia, and current smoker. In this study, we evaluate the clinical outcomes and CMR imaging characteristics of patients with and without SMuRFs who presented with first-presentation STEMI. Methods: Patients from the Third DANish Study of Acute Treatment of Patients With ST-Segment Elevation Myocardial Infarction (DANAMI-3) with first-presentation STEMI were classified into those with no SMuRFs vs. those with at least one SMuRF. Results: We identified 2,046 patients; 283 (14%) SMuRFless and 1,763 (86%) had >0 SMuRF. SMuRFless patients were older (66 vs. 61 years, p < 0.001) with more males (84 vs. 74%, p < 0.001), more likely to have left anterior descending artery (LAD) as the culprit artery (50 vs. 42%, p = 0.009), and poor pre-PCI (percutaneous coronary intervention) TIMI (thrombolysis in myocardial infarction) flow ≤1 (78 vs. 64%; p < 0.001). There was no difference in all-cause mortality, non-fatal reinfarction, or hospitalization for heart failure at 30 days or at long-term follow-up. CMR imaging was performed on 726 patients. SMuRFless patients had larger acute infarct size (17 vs. 13%, p = 0.04) and a smaller myocardial salvage index (42 vs. 50%, p = 0.02). These differences were attenuated when the higher LAD predominance and/or TIMI 0-1 flow were included in the model. Conclusion: Despite no difference in 30-day mortality, SMuRFless patients had a larger infarct size and a smaller myocardial salvage index following first-presentation STEMI. This association was mediated by a larger proportion of LAD culprits and poor TIMI flow pre-PCI.

Angiographic outcome in patients treated with deferred stenting after ST-segment elevation myocardial infarction-results from DANAMI-3-DEFER.

AIMS: Stent implantation during primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) occasionally results in flow disturbances and distal embolization, which may cause adverse clinical outcomes. Deferred stent implantation seems to reduce the impairment on myocardial function, although the mechanisms have not been clarified. We sought to evaluate whether deferred stenting could reduce flow disturbance in patients treated with primary PCI. METHODS AND RESULTS: Patients with STEMI included in the DANAMI-3-DEFER trial were randomized to deferred versus immediate stent implantation. The primary and secondary outcomes of this substudy were the incidences of slow/no reflow and distal embolization. A total of 1205 patients were included. Deferred stenting (n = 594) resulted in lower incidences of distal embolization [odds ratio (OR) 0.67, 95% confidence interval (CI) 0.46-0.98, P = 0.040] and slow/no reflow (OR 0.60, 95%CI 0.37-0.97, P = 0.039). In high-risk subgroups, the protective effect was greatest in patients >65 years of age (slow/no reflow: OR 0.36, 95% CI 0.17-0.72, P = 0.004 and distal embolization: OR 0.34, 95% CI 0.18-0.63, P = 0.001), in patients presenting with occluded culprit artery at admission (slow/no reflow: OR 0.33, 95% CI 0.16-0.65, P = 0.001 and distal embolization: OR 0.54, 95% CI 0.31-0.96, P = 0.036) and in patients with thrombus grade >3 (slow/no reflow: OR 0.37, 95% CI 0.20-0.67, P = 0.001 and distal embolization: OR 0.39, 95% CI 0.24-0.64, P < 0.001) with a significant P for interaction for all. CONCLUSION: Deferred stent implantation reduces the incidences of slow/no reflow and distal embolization, especially in older patients and in those with total coronary occlusion or high level of thrombus burden.

Blood-Pressure Targets in Comatose Survivors of Cardiac Arrest.

BACKGROUND: Evidence to support the choice of blood-pressure targets for the treatment of comatose survivors of out-of-hospital cardiac arrest who are receiving intensive care is limited. METHODS: In a double-blind, randomized trial with a 2-by-2 factorial design, we evaluated a mean arterial blood-pressure target of 63 mm Hg as compared with 77 mm Hg in comatose adults who had been resuscitated after an out-of-hospital cardiac arrest of presumed cardiac cause; patients were also assigned to one of two oxygen targets (reported separately). The primary outcome was a composite of death from any cause or hospital discharge with a Cerebral Performance Category (CPC) of 3 or 4 within 90 days (range, 0 to 5, with higher categories indicating more severe disability; a category of 3 or 4 indicates severe disability or coma). Secondary outcomes included neuron-specific enolase levels at 48 hours, death from any cause, scores on the Montreal Cognitive Assessment (range, 0 to 30, with higher scores indicating better cognitive ability) and the modified Rankin scale (range, 0 to 6, with higher scores indicating greater disability) at 3 months, and the CPC at 3 months. RESULTS: A total of 789 patients were included in the analysis (393 in the high-target group and 396 in the low-target group). A primary-outcome event occurred in 133 patients (34%) in the high-target group and in 127 patients (32%) in the low-target group (hazard ratio, 1.08; 95% confidence interval [CI], 0.84 to 1.37; P = 0.56). At 90 days, 122 patients (31%) in the high-target group and 114 patients (29%) in the low-target group had died (hazard ratio, 1.13; 95% CI, 0.88 to 1.46). The median CPC was 1 (interquartile range, 1 to 5) in both the high-target group and the low-target group; the corresponding median modified Rankin scale scores were 1 (interquartile range, 0 to 6) and 1 (interquartile range, 0 to 6), and the corresponding median Montreal Cognitive Assessment scores were 27 (interquartile range, 24 to 29) and 26 (interquartile range, 24 to 29). The median neuron-specific enolase level at 48 hours was also similar in the two groups. The percentages of patients with adverse events did not differ significantly between the groups. CONCLUSIONS: Targeting a mean arterial blood pressure of 77 mm Hg or 63 mm Hg in patients who had been resuscitated from cardiac arrest did not result in significantly different percentages of patients dying or having severe disability or coma.

Oxygen Targets in Comatose Survivors of Cardiac Arrest.

BACKGROUND: The appropriate oxygenation target for mechanical ventilation in comatose survivors of out-of-hospital cardiac arrest is unknown. METHODS: In this randomized trial with a 2-by-2 factorial design, we randomly assigned comatose adults with out-of-hospital cardiac arrest in a 1:1 ratio to either a restrictive oxygen target of a partial pressure of arterial oxygen (Pao2) of 9 to 10 kPa (68 to 75 mm Hg) or a liberal oxygen target of a Pao2 of 13 to 14 kPa (98 to 105 mm Hg); patients were also assigned to one of two blood-pressure targets (reported separately). The primary outcome was a composite of death from any cause or hospital discharge with severe disability or coma (Cerebral Performance Category [CPC] of 3 or 4; categories range from 1 to 5, with higher values indicating more severe disability), whichever occurred first within 90 days after randomization. Secondary outcomes were neuron-specific enolase levels at 48 hours, death from any cause, the score on the Montreal Cognitive Assessment (ranging from 0 to 30, with higher scores indicating better cognitive ability), the score on the modified Rankin scale (ranging from 0 to 6, with higher scores indicating greater disability), and the CPC at 90 days. RESULTS: A total of 789 patients underwent randomization. A primary-outcome event occurred in 126 of 394 patients (32.0%) in the restrictive-target group and in 134 of 395 patients (33.9%) in the liberal-target group (hazard ratio, 0.95; 95% confidence interval, 0.75 to 1.21; P = 0.69). At 90 days, death had occurred in 113 patients (28.7%) in the restrictive-target group and in 123 (31.1%) in the liberal-target group. On the CPC, the median category was 1 in the two groups; on the modified Rankin scale, the median score was 2 in the restrictive-target group and 1 in the liberal-target group; and on the Montreal Cognitive Assessment, the median score was 27 in the two groups. At 48 hours, the median neuron-specific enolase level was 17 µg per liter in the restrictive-target group and 18 µg per liter in the liberal-target group. The incidence of adverse events was similar in the two groups. CONCLUSIONS: Targeting of a restrictive or liberal oxygenation strategy in comatose patients after resuscitation for cardiac arrest resulted in a similar incidence of death or severe disability or coma.

Self-assessed health status and associated mortality in endocarditis: secondary findings from the POET trial.

PURPOSE: Self-assessed poor health status is associated with increased risk of mortality in several cardiovascular conditions, but has not been investigated in patients with endocarditis. We examined health status and mortality in patients with endocarditis. METHODS: This is a re-specified substudy of the randomized POET endocarditis trial, which included 400 patients. Patients completed the single-question self-assessed health status from the Short-Form 36 questionnaire at time of randomization and were categorized as having poor or non-poor (excellent/very good, good, or fair) health status. Self-assessed health status and all-cause mortality were examined by a Cox regression model. RESULTS: Self-assessed health status was completed by 266 (67%) patients with a mean age of 68.0 years (± 11.8), 54 (20%) were females, and 86 (32%) had one or more major concurrent medical conditions besides endocarditis. The self-assessed health status distribution was poor (n = 21, 8%) and non-poor (n = 245, 92%). The median follow-up was 3.3 years and death occurred in 9 (43%) and 48 (20%) patients reporting poor and non-poor health status, respectively, and mortality rates [mortality/100 person-years, 95% confidence interval (CI)] were 18.1 (95% CI 9.4-34.8) and 5.4 (95% CI 4.1-7.2), i.e., the crude hazard ratio for death was 3.4 (95% CI: 1.7-7.0, p < 0.01). CONCLUSION: Self-assessed poor health status compared with non-poor health status as assessed by a single question was associated with a threefold increased long-term mortality in patients with endocarditis.

NT-proBNP and ICD in Nonischemic Systolic Heart Failure: Extended Follow-Up of the DANISH Trial.

OBJECTIVES: In this extended follow-up study of the DANISH (Danish Study to Assess the Efficacy of Implantable Cardioverter Defibrillators in Patients with Non-ischemic Systolic Heart Failure on Mortality) trial, adding 4 years of additional follow-up, we examined the effect of implantable cardioverter-defibrillator (ICD) implantation according to baseline N-terminal pro-B-type natriuretic peptide (NT-proBNP) level. BACKGROUND: In the DANISH trial, NT-proBNP level at baseline appeared to modify the response to ICD implantation. METHODS: In the DANISH trial, 1,116 patients with nonischemic systolic HF were randomized to receive an ICD (N = 556) or usual clinical care (N = 550). Outcomes were analyzed according to NT-proBNP levels (below/above median) at baseline. The primary outcome was death from any cause. RESULTS: All 1,116 patients in the DANISH trial had an available NT-proBNP measurement at baseline (median: 1,177 pg/mL; range: 200-22,918 pg/mL). There was a trend toward a reduction in all-cause death with ICD implantation, compared with usual clinical care, in patients with NT-proBNP levels lower than the median (HR: 0.75 [95% CI: 0.55-1.03]), but not in those with higher NT-proBNP levels (HR: 0.95 [95% CI: 0.74-1.21]) (Pinteraction = 0.28). Similarly, ICD implantation significantly reduced the rate of cardiovascular (CV) and sudden cardiovascular death (SCD) in patients with NT-proBNP levels lower than the median (CV death, HR: 0.69 [95% CI: 0.47-1.00]; SCD, HR: 0.37 [95% CI: 0.19-0.75]), but not in those with higher levels (CV death, HR: 0.94 [95% CI: 0.70-1.25]; SCD, HR: 0.86 [95% CI: 0.49-1.51]) (Pinteraction = 0.20 and 0.08 for CV death and SCD, respectively). CONCLUSIONS: Lower baseline NT-proBNP levels could identify patients with nonischemic systolic HF who may derive benefit from ICD implantation.

Bleeding Episodes in Patients With Non-ST-Segment Elevation Acute Coronary Syndrome Undergoing Very Early Versus Standard Care Invasive Examination (from the Very EaRly vs Deferred Invasive Evaluation Using Computerised Tomography [VERDICT] Trial).

Bleeding is known to influence the prognosis in patients with acute coronary syndromes. In this predefined secondary outcome analysis of the Very EaRly vs Deferred Invasive evaluation using Computerized Tomography (VERDICT) trial, we investigated whether a very early invasive coronary angiography (ICA), compared with one performed within 48 to 72 hours (standard care), was associated with fewer serious bleedings. Furthermore, we tested the association between demographic data including GRACE score and serious bleedings as well as bleedings and mortality. In the 2,147 patients included in the main study, bleedings within 30 days of admission were assessed based on Thrombolysis In Myocardial Infarction and Bleeding Academic Research Consortium criteria. Differences were calculated by cumulative incidence methods and Grays test. Variables associated with bleeding and mortality were estimated by Cox proportional hazard models. Serious (Bleeding Academic Research Consortium 3abc) bleeding rates were low (15 [1.4%, standard] vs 12 [1.2%, early], p = 0.56). There were no fatal bleedings or serious bleedings before ICA in either group. By multivariate analysis, there was no difference in bleedings between the 2 groups. Female gender (hazard ratio [HR] 2.7, 95% confidence interval [CI] 1.2 to 6.4; p = 0.02), anemia (HR 7.0, 95% CI 2.8 to 17.0; p <0.001), and increasing blood pressure (HR 1.3, 95% CI 1.1 to 1.5; p = 0.01) were individually associated with serious bleeding, whereas GRACE score >140 was not (HR 1.03, 95% CI 0.4 to 2.9; p = 0.96). In conclusion, serious bleedings were few, and there were none before ICA in either group. A very early invasive strategy did not reduce serious bleedings within 30 days, which was associated with female gender, increasing blood pressure, and anemia.

The impact of partial-oral endocarditis treatment on anxiety and depression in the POET trial.

BACKGROUND: The Partial-Oral versus Intravenous Antibiotic Treatment of Endocarditis Trial (POET) found that partial-oral outpatient treatment was non-inferior to conventional in-hospital intravenous treatment in patients with left-sided infective endocarditis. We examined the impact of treatment strategy on levels of anxiety and depression. METHODS: Patients completed the Hospital Anxiety and Depression Scale (HADS) at randomization, at antibiotic completion, and after month 3 and month 6. Changes in anxiety and depression (each subdimension 0-21, high scores indicating worse) were calculated using a repeated measure analysis of covariance model with primary assessment after 6 months. Change in score of 1.7 represented a minimal clinical important difference (MCID). RESULTS: Among the 400 patients enrolled in the POET trial, 263 (66%) completed HADS at randomization with reassessment rates of 86-87% at the three subsequent timepoints. Patients in the partial-oral group and the intravenous group had similar improvements after 6 months in levels of anxiety (-1.8 versus -1.6, P = 0.62) and depression (-2.1 versus -1.9, P = 0.63), although patients in the partial-oral group had numerically lower levels of anxiety and depression throughout. An improvement in MCID scores after 6 months was reported by 47% versus 45% (p = 0.80) patients for anxiety and by 51% versus 54% (p = 0.70) for depression. CONCLUSION: Patients with endocarditis receiving partial-oral outpatient treatment reported similar significant improvements in anxiety and depression at 6 months, as compared to conventionally treated, but numerically lower levels throughout. These findings support the usefulness of partial-oral treatment.

Is It Safe to Mobilize Patients Very Early After Transfemoral Coronary Procedures? (SAMOVAR): A Randomized Clinical Trial.

BACKGROUND: Coronary angiography (CAG) and percutaneous coronary intervention (PCI) are performed via the femoral or radial arteries. In patients examined via transfemoral access, closure devices facilitate hemostasis, but it is unknown whether it is safe to mobilize these patients immediately and how acceptable this may be in terms of patient comfort. OBJECTIVE: The aims of this study were to investigate bleeding complications in patients mobilized immediately after transfemoral CAG or PCI compared with patients on bed rest (BR) for 2 hours after the procedure and, furthermore, to investigate patient comfort in relation to mobilization and BR. METHODS: SAMOVAR was a noninferiority trial with patients randomized to immediate mobilization (IM) or 2 hours of BR after transfemoral CAG or PCI and use of the AngioSeal as a closure device and reversal of heparin effect. The primary end point was development of hematoma greater than 5 cm, pseudoaneurysm, or bleeding requiring blood transfusion. Secondary end points were oozing from the puncture site, small hematoma, and patient comfort. RESULTS: Of 2027 patients (IM, 1010; BR, 1017), 40% underwent PCI. The primary outcome was recorded in 0.7% patients randomized to IM versus 0.5% in BR ( P = .58). There was no difference in the incidence of small hematoma, whereas persistent oozing was seen slightly more often after IM compared with BR (12% vs 9%, P = .04). Patients mobilized immediately reported less back pain and micturition problems ( P < .001). CONCLUSIONS: In patients who had CAG and PCI performed through transfemoral access, reversal of anticoagulation and use of closure devices allowed IM with low rates of complications and improved patient comfort.

Long-Term Follow-Up of DANISH (The Danish Study to Assess the Efficacy of ICDs in Patients With Nonischemic Systolic Heart Failure on Mortality).

BACKGROUND: DANISH (The Danish Study to Assess the Efficacy of Implantable Cardioverter Defibrillators [ICDs] in Patients With Nonischemic Systolic Heart Failure on Mortality) found that primary-prevention ICD implantation was not associated with an overall survival benefit in patients with nonischemic systolic heart failure during a median follow-up of 5.6 years, although there was a beneficial effect on all-cause mortality in patients ≤70 years. This study presents an additional 4 years of follow-up data from DANISH. METHODS: In DANISH, 556 patients with nonischemic systolic heart failure were randomized to receive an ICD and 560 to receive usual clinical care and followed until June 30, 2016. In this long-term follow-up study, patients were followed until May 18, 2020. Analyses were conducted for the overall population and according to age (≤70 and >70 years). RESULTS: During a median follow-up of 9.5 years (25th-75th percentile, 7.9-10.9 years), 208/556 patients (37%) in the ICD group and 226/560 patients (40%) in the control group died. Compared with the control group, the ICD group did not have significantly lower all-cause mortality (hazard ratio [HR] 0.89, [95% CI, 0.74-1.08]; P = 0.24). In patients ≤70 years (n = 829), all-cause mortality was lower in the ICD group than the control group (117/389 [30%] versus 158/440 [36%]; HR, 0.78 [95% CI, 0.61-0.99]; P = 0.04), whereas in patients >70 years (n = 287), all-cause mortality was not significantly different between the ICD and control group (91/167 [54%] versus 68/120 [57%]; HR, 0.92 [95% CI, 0.67-1.28]; P = 0.75). Cardiovascular death showed similar trends (overall, 147/556 [26%] versus 164/560 [29%]; HR, 0.87 [95% CI, 0.70-1.09]; P = 0.20; ≤70 years, 87/389 [22%] versus 122/440 [28%]; HR, 0.75 [95% CI, 0.57-0.98]; P = 0.04; >70 years, 60/167 [36%] versus 42/120 [35%]; HR, 0.97 [95% CI, 0.65-1.45]; P = 0.91). The ICD group had a significantly lower incidence of sudden cardiovascular death in the overall population (35/556 [6%] versus 57/560 [10%]; HR, 0.60 [95% CI, 0.40-0.92]; P = 0.02) and in patients ≤70 years (19/389 [5%] versus 49/440 [11%]; HR, 0.42 [95% CI, 0.24-0.71]; P = 0.0008), but not in patients >70 years (16/167 [10%] versus 8/120 [7%]; HR, 1.34 [95% CI, 0.56-3.19]; P = 0.39). CONCLUSIONS: During a median follow-up of 9.5 years, ICD implantation did not provide an overall survival benefit in patients with nonischemic systolic heart failure. In patients ≤70 years, ICD implantation was associated with a lower incidence of all-cause mortality, cardiovascular death, and sudden cardiovascular death.

Ischemia From Nonculprit Stenoses Is Not Associated With Reduced Culprit Infarct Size in Patients with ST-Segment-Elevation Myocardial Infarction.

BACKGROUND: In patients with ST-segment-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention, reperfusion injury accounts for a significant fraction of the final infarct size, which is directly related to patient prognosis. In animal studies, brief periods of ischemia in noninfarct-related (nonculprit) coronary arteries protect the culprit myocardium via remote ischemic preconditioning. Positive fractional flow reserve (FFR) documents functional significant coronary nonculprit stenosis, which may offer remote ischemic preconditioning of the culprit myocardium. The aim of the study was to investigate the association between functional significant, multivessel disease (MVD) and reduced culprit final infarct size or increased myocardial salvage (myocardial salvage index [MSI]) in a large contemporary cohort of STEMI patients. METHODS: Cardiac magnetic resonance was performed in 610 patients with STEMI at day 1 and 3 months after primary percutaneous coronary intervention. Patients were stratified into 3 groups according to FFR measurements in nonculprit stenosis (if any): angiographic single vessel disease (SVD), FFR nonsignificant MVD (functional SVD), or FFR-significant, functional MVD. RESULTS: A total of 431 (71%) patients had SVD, 35 (6%) had functional SVD, and 144 (23%) had functional MVD. There was no difference in final infarct size (mean infarct size [%left ventricular mass] SVD, 9±3%; functional SVD, 9±3%; and functional MVD, 9±3% [P=0.82]) or in MSI between groups (mean MSI [%left] SVD, 66±23%; functional SVD, 68±19%; and functional MVD, 69±19% [P=0.62]). In multivariable analyses, functional MVD was not associated with larger MSI (P=0.56) or smaller infarct size (P=0.55). CONCLUSIONS: Functional MVD in nonculprit myocardium was not associated with reduced culprit final infarct size or increased MSI following STEMI. This is important knowledge for future studies examining a cardioprotective treatment in patients with STEMI, as a possible confounding effect of FFR-significant, functional MVD can be discarded.
