Carcinoid Heart Disease With Hypoxemia.

Patent foramen ovale (PFO) complicated with carcinoid heart disease (CHD) can cause severe hypoxia and worsening clinical conditions. We report the case of a patient with CHD in poor general condition with multiple severe valve regurgitations and PFO, who underwent successful percutaneous closure of the PFO.

The characteristics and outcomes in patients with acute heart failure who used tolvaptan: from KCHF registry.

AIMS: The use of tolvaptan is increasing in clinical practice in Japan. However, the characteristics of patients who used tolvaptan and the timing of its use in patients with acute heart failure (AHF) are not fully elucidated. METHODS AND RESULTS: Among consecutive 4056 patients in the Kyoto Congestive Heart Failure registry, we analysed 3802 patients after excluding patients on dialysis, prior or unknown tolvaptan use at admission, and unknown timing of tolvaptan use, and we divided them into two groups: tolvaptan use (N = 773) and no tolvaptan use (N = 3029). The prevalence of tolvaptan use varied widely from 48.7% to 0% across the participating centres. Factors independently associated with tolvaptan use were diabetes, poor medical adherence, oedema, pleural effusion, hyponatraemia, estimated glomerular filtration rate < 30 mL/min/1.73 m2 , moderate/severe tricuspid regurgitation, dobutamine infusion within 24 h, and additional inotropes infusion beyond 24 h after admission. The mortality rate at 90 days after admission was significantly higher in the tolvaptan use group than in the no tolvaptan use group (14.3% vs. 8.6%, P = 0.049). However, after adjustment, the excess mortality risk of tolvaptan use relative to no tolvaptan use was no longer significant (hazard ratio = 1.53, 95% confidence interval = 0.77-3.02, P = 0.22). Patients with tolvaptan use had a longer hospital stay [median (interquartile range): 22 (15-34) days vs. 15 (11-21) days, P < 0.0001] and a higher prevalence of worsening renal failure (47.0% vs. 31.8%, P < 0.0001) and worsening heart failure (24.8% vs. 14.4%, P < 0.0001) than those without. CONCLUSIONS: AHF patients with tolvaptan use had more congestive status with poorer in-hospital outcomes and higher short-term mortality than those without tolvaptan use.

Tricuspid regurgitation in elderly patients with acute heart failure: insights from the KCHF registry.

AIMS: Several studies demonstrated that tricuspid regurgitation (TR) is associated with poor clinical outcomes. However, data on patients with TR who experienced acute heart failure (AHF) remains scarce. The purpose of this study is to evaluate the association between TR and clinical outcomes in patients admitted with AHF, using a large-scale Japanese AHF registry. METHODS AND RESULTS: The current study population consisted of 3735 hospitalized patients due to AHF in the Kyoto Congestive Heart Failure (KCHF) registry. TR grades were assessed according to the routine clinical practice at each participating centre. We compared the baseline characteristics and outcomes according to the severity of TR. The primary outcome was all-cause death. The secondary outcome was hospitalization for heart failure (HF). The median age of the entire study population was 80 (interquartile range: 72-86) years. One thousand two hundred five patients (32.3%) had no TR, while mild, moderate, and severe TR was found in 1537 patients (41.2%), 776 patients (20.8%), and 217 patients (5.8%), respectively. Pulmonary hypertension, significant mitral regurgitation, and atrial fibrillation/flutter were strongly associated with the development of moderate/severe of TR, while left ventricular ejection fraction <50% was inversely associated with it. Among 993 patients with moderate/severe TR, the number of patients who underwent surgical intervention for TR within 1 year was only 13 (1.3%). The median follow-up duration was 475 (interquartile range: 365-653) days with 94.0% follow-up at 1 year. As the TR severity increased, the cumulative 1 year incidence of all-cause death and HF admission proportionally increased ([14.8%, 20.3%, 23.4%, 27.0%] and [18.9%, 23.0%, 28.5%, 28.4%] in no, mild, moderate, and severe TR, respectively). Compared with no TR, the adjusted risks of patients with mild, moderate, and severe TR were significant for all-cause death (hazard ratio [95% confidence interval]: 1.20 [1.00-1.43], P = 0.0498, 1.32 [1.07-1.62], P = 0.009, and 1.35 [1.00-1.83], P = 0.049, respectively), while those were not significant for hospitalization for HF (hazard ratio [95% confidence interval]: 1.16 [0.97-1.38], P = 0.10, 1.19 [0.96-1.46], P = 0.11, and 1.20 [0.87-1.65], P = 0.27, respectively). The higher adjusted HRs of all the TR grades relative to no TR were significant for all-cause death in patients aged <80 years, but not in patients aged ≥80 years with significant interaction. CONCLUSIONS: In a large Japanese AHF population, the grades of TR could successfully stratify the risk of all-cause death. However, the association of TR with mortality was only modest and attenuated in patients aged 80 or more. Further research is warranted to evaluate how to follow up and manage TR in this elderly population.

Public assistance in patients with acute heart failure: a report from the KCHF registry.

AIMS: There is a scarcity of data on the post-discharge prognosis in acute heart failure (AHF) patients with a low-income but receiving public assistance. The study sought to evaluate the differences in the clinical characteristics and outcomes between AHF patients receiving public assistance and those not receiving public assistance. METHODS AND RESULTS: The Kyoto Congestive Heart Failure registry was a physician-initiated, prospective, observational, multicentre cohort study enrolling 4056 consecutive patients who were hospitalized due to AHF for the first time between October 2014 and March 2016. The present study population consisted of 3728 patients who were discharged alive from the index AHF hospitalization. We divided the patients into two groups, those receiving public assistance and those not receiving public assistance. After assessing the proportional hazard assumption of public assistance as a variable, we constructed multivariable Cox proportional hazard models to estimate the risk of the public assistance group relative to the no public assistance group. There were 218 patients (5.8%) receiving public assistance and 3510 (94%) not receiving public assistance. Patients in the public assistance group were younger, more frequently had chronic coronary artery disease, previous heart failure hospitalizations, current smoking, poor medical adherence, living alone, no occupation, and a lower left ventricular ejection fraction than those in the no public assistance group. During a median follow-up of 470 days, the cumulative 1 year incidences of all-cause death and heart failure hospitalizations after discharge did not differ between the public assistance group and no public assistance group (13.3% vs. 17.4%, P = 0.10, and 28.3% vs. 23.8%, P = 0.25, respectively). After adjusting for the confounders, the risk of the public assistance group relative to the no public assistance group remained insignificant for all-cause death [hazard ratio (HR), 0.97; 95% confidence interval (CI), 0.69-1.32; P = 0.84]. Even after taking into account the competing risk of all-cause death, the adjusted risk within 180 days in the public assistance group relative to the no public assistance group remained insignificant for heart failure hospitalizations (HR, 0.93; 95% CI, 0.64-1.34; P = 0.69), while the adjusted risk beyond 180 days was significant (HR, 1.56; 95% CI, 1.07-2.29; P = 0.02). CONCLUSIONS: The AHF patients receiving public assistance as compared with those not receiving public assistance had no significant excess risk for all-cause death at 1 year after discharge or a heart failure hospitalization within 180 days after discharge, while they did have a significant excess risk for heart failure hospitalizations beyond 180 days after discharge.

Coronary angiography in patients with acute heart failure: from the KCHF registry.

AIMS: Little is known about the characteristics and outcomes of patients who undergo coronary angiography during heart failure (HF) hospitalization, as well as those with coronary stenosis, and those who underwent coronary revascularization. METHODS AND RESULTS: We analysed 2163 patients who were hospitalized for HF without acute coronary syndrome or prior HF hospitalization. We compared patient characteristics and 1 year clinical outcomes according to (i) patients with versus without coronary angiography, (ii) patients with versus without coronary stenosis, and (iii) patients with versus without coronary revascularization. The primary outcome measure was the composite of all-cause death or HF hospitalization. Coronary angiography was performed in 37.0% of patients. In the multivariable logistic regression analysis, factors independently associated with coronary angiography were age < 80 years [adjusted odds ratio (OR) = 1.76, 95% confidence interval (CI) = 1.41-2.20, P < 0.001], men (adjusted OR = 1.28, 95% CI = 1.03-1.59, P = 0.02), diabetes (adjusted OR = 1.27, 95% CI = 1.02-1.60, P = 0.04), no atrial fibrillation or flutter (adjusted OR = 1.45, 95% CI = 1.17-1.82, P < 0.001), no prior device implantation (adjusted OR = 1.81, 95% CI = 1.13-2.91, P = 0.01), current smoking (adjusted OR = 1.40, 95% CI = 1.05-1.87, P = 0.02), no cognitive dysfunction (adjusted OR = 1.90, 95% CI = 1.34-2.69, P < 0.001), ambulatory status (adjusted OR = 2.89, 95% CI = 2.03-4.10, P < 0.001), HF with reduced ejection fraction (adjusted OR = 1.55, 95% CI = 1.24-1.93, P < 0.001), estimated glomerular filtration rate ≥ 30 mL/min/1.73 m2 (adjusted OR = 1.93, 95% CI = 1.45-2.58, P < 0.001), no anaemia (adjusted OR = 1.27, 95% CI = 1.02-1.59, P = 0.04), and no prescription of ß-blockers prior to admission (adjusted OR = 1.32, 95% CI = 1.03-1.68, P = 0.03). Patients who underwent coronary angiography had a lower risk of the primary outcome [adjusted hazard ratio (HR) = 0.70, 95% CI = 0.58-0.85, P < 0.001]. Among the patients who underwent coronary angiography, those with coronary stenosis (38.9%) did not have lower risk of the primary outcome measure than those without coronary stenosis (adjusted HR = 0.93, 95% CI = 0.65-1.32, P = 0.68). Among the patients with coronary stenosis, those with coronary revascularization (54.3%) did not have higher risk of the primary outcome measure than those without coronary revascularization (adjusted HR = 1.36, 95% CI = 0.84-2.21, P = 0.22). CONCLUSIONS: In patients with acute HF, patients who underwent coronary angiography had a lower risk of clinical outcomes and were significantly different from those who did not undergo coronary angiography.

Lower In-Hospital Mortality With Beta-Blocker Use at Admission in Patients With Acute Decompensated Heart Failure.

Background It remains unclear whether beta-blocker use at hospital admission is associated with better in-hospital outcomes in patients with acute decompensated heart failure. Methods and Results We evaluated the factors independently associated with beta-blocker use at admission, and the effect of beta-blocker use at admission on in-hospital mortality in 3817 patients with acute decompensated heart failure enrolled in the Kyoto Congestive Heart Failure registry. There were 1512 patients (39.7%) receiving, and 2305 patients (60.3%) not receiving beta-blockers at admission for the index acute decompensated heart failure hospitalization. Factors independently associated with beta-blocker use at admission were previous heart failure hospitalization, history of myocardial infarction, atrial fibrillation, cardiomyopathy, and estimated glomerular filtration rate <30 mL/min per 1.73 m2. Factors independently associated with no beta-blocker use were asthma, chronic obstructive pulmonary disease, lower body mass index, dementia, older age, and left ventricular ejection fraction <40%. Patients on beta-blockers had significantly lower in-hospital mortality rates (4.4% versus 7.6%, P<0.001). Even after adjusting for confounders, beta-blocker use at admission remained significantly associated with lower in-hospital mortality risk (odds ratio, 0.41; 95% CI, 0.27-0.60, P<0.001). Furthermore, beta-blocker use at admission was significantly associated with both lower cardiovascular mortality risk and lower noncardiovascular mortality risk. The association of beta-blocker use with lower in-hospital mortality risk was relatively more prominent in patients receiving high dose beta-blockers. The magnitude of the effect of beta-blocker use was greater in patients with previous heart failure hospitalization than in patients without (P for interaction 0.04). Conclusions Beta-blocker use at admission was associated with lower in-hospital mortality in patients with acute decompensated heart failure.

Clinical Outcomes After Percutaneous Coronary Intervention in Patients With Cancer.

BACKGROUND: The aim of this study is to evaluate clinical outcomes after percutaneous coronary intervention (PCI) in patients with cancer.Methods and Results:Cancer screening was recommended before PCI in consecutive 1,303 patients who underwent their first PCI. By using cancer screening, cancer was diagnosed in 29 patients (2.2%). In total, 185 patients had present or a history of cancer. Patients with cancer more often suffered from non-cardiac death than those without (4.4% vs. 1.5%, P=0.006), and patients with cancer requiring ongoing therapy (n=18) more often suffered from major bleeding compared with those with recently (≤12 months) diagnosed cancer who do not have ongoing therapy (n=59) (16.7% vs. 3.4%, P=0.049). During the 1-year follow up, 25 patients (2.0%) were diagnosed as having cancer, in which 48.0% of bleeding events led to a cancer diagnosis. Patients with high bleeding risk according to the Academic Research Consortium for high bleeding risk (ARC-HBR) were associated with a greater 1-year major bleeding risk than those without high bleeding risk in patients with (7.9% vs. 0.0%, P=0.02) and without cancer (7.1% vs. 2.5%, P<0.001), respectively. CONCLUSIONS: Cancer was diagnosed in 2.2% of 1,303 unselected patients before PCI by cancer screening and in 2.0% within 1-year after PCI. Cancer was associated with a greater risk of non-cardiac death, whereas ongoing active cancer was associated with greater risk of major bleeding. ARC-HBR criteria successfully identified high-bleeding risk patients, irrespective of the presence or absence of cancer.

Aortic Complex Rupture After Transcatheter Aortic Valve Implantation.

Aortic complex rupture is one of the most critical complications associated with transcatheter aortic valve implantation (TAVI). Its incidence is rare, and its mechanism varies by case; therefore, it is difficult to identify the predictors of complex rupture. Herein, we report a clinical case series of aortic complex rupture. Within our cohort, the frequency of complex rupture was 0.8% (4/497 consecutive patients) with an in-hospital mortality of 0. Among these four patients with complex rupture, two underwent emergent thoracotomy and surgical hemostasis without a heart-lung machine and surgical aortic valve replacement, whereas the other two were conservatively managed. The case overview revealed the following similarities: all the patients were elderly, small women; balloon-expandable valves were used; the annulus area was small with heavily calcified leaflet; and aggressive treatment strategy was used (i.e., oversizing and post-dilatation). In such cases, TAVI should be performed with a careful strategy. Once aortic complex rupture occurs, damage can be minimized through cooperation with an institutional heart team and calm management.
