ABSTRACT

Background: Owing to the minimally invasive nature of transcatheter aortic valve replacement (TAVR), TAVR seems to be preferred in patients with cancer; however, related research on the clinical efficacy and safety of TAVR in patients with cancer and severe aortic stenosis is limited, and conclusions are controversial. This study aimed to evaluate the clinical outcomes of patients with cancer who underwent TAVR. Method and results: We conducted a systematic review and meta-analysis to investigate the clinical outcomes in patients with and without cancer who underwent TAVR. We systematically reviewed and analyzed 15 studies (195,658 patients) published in PubMed and Cochrane Library databases between January 2022 and January 2023. The primary outcomes were short-term (in-hospital or 30-day) and long-term (≥12 months) mortality. The prevalence of current or previous cancer in the patients undergoing TAVR was 19.8 % (38,695 patients). Patients with cancer had a lower risk of short-term mortality (odds ratio [OR] 0.69, 95 % confidence interval [CI] 0.61-0.77, P < 0.001) but a higher risk of long-term mortality (OR 1.54, 95 % CI 1.35-1.76, P < 0.001) than those without cancer. Patients with cancer had a lower incidence of postprocedural stroke and acute kidney injury but a higher incidence of pacemaker implantation than patients without cancer. Conclusions: Patients with cancer undergoing TAVR have a good short-term prognosis and acceptable perioperative complications compared with patients without cancer. However, the long-term outcomes are contingent on cancer survival.

ABSTRACT

BACKGROUND: Women with acute myocardial infarction (AMI) often present a worse risk profile and experience a higher rate of in-hospital mortality than men. However, sex differences in post-discharge prognoses remain inadequately investigated. We examined the impact of sex on 1-year post-discharge outcomes in patients with AMI undergoing percutaneous coronary intervention.Methods and Results: We extracted patient-level data for the period January 2017-December 2018 from the J-PCI OUTCOME Registry, endorsed by the Japanese Association of Cardiovascular Intervention and Therapeutics. One-year all-cause and cardiovascular mortality and major adverse cardiovascular events were compared between men and women. In all, 29,856 AMI patients were studied, with 6,996 (23.4%) being women. Women were significantly older and had a higher prevalence of comorbidities than men. Crude all-cause mortality was significantly higher among women than men (7.5% vs. 5.4% [P<0.001] for ST-elevation myocardial infarction [STEMI]; 7.0% vs. 5.2% [P=0.006] for non-STEMI). These sex-related differences in post-discharge outcomes were attenuated after stratification by age. Multivariate analysis demonstrated an increase in all-cause mortality in both sexes with increasing age and advanced-stage chronic kidney disease (CKD). CONCLUSIONS: Within this nationwide cohort, women had worse clinical outcomes following AMI than men. However, these sex-related differences in outcomes diminished after adjusting for age. In addition, CKD was significantly associated with all-cause mortality in both sexes.

ABSTRACT

BACKGROUND: A rotational activation pattern (RAP) around the localized line of a conduction block often correlates with sites specific to the critical zones of ventricular tachycardia (VT). The wavefront direction during substrate mapping affects manifestation of the RAP and line of block. OBJECTIVE: The purpose of this study was to investigate the most optimal cardiac rhythm for identifying RAP and line of block in substrate mapping. METHODS: We retrospectively evaluated 71 maps (median 3205 points/map) in 46 patients (65 ± 15 years; 33% with ischemic cardiomyopathy) who underwent high-density substrate mapping and ablation of scar-related VT. Appearance of a RAP during sinus, right ventricular (RV)-paced, left ventricular (LV)-paced, and biventricular-paced rhythms was investigated. RESULTS: RAP was identified in 24 of 71 maps (34%) in the region where wavefronts from a single direction reached but not in the region where wavefronts from multiple directions centripetally collided. The probability of identifying the RAP depended on scar location; that is, anteroseptal and inferoseptal, inferior and apical, and basal lateral RAPs were likely to be identified during sinus/atrial, RV-paced, and LV-paced rhythms, respectively. In 13 patients, the RAP was not evident in the baseline map but became apparent during remapping in the other rhythm, in which the wavefront reached the site earlier within the entire activation time. CONCLUSION: The optimal rhythm for substrate mapping depends on the spatial distribution of the area of interest. A paced rhythm with pacing sites near the scar may facilitate the identification of critical VT zones.

ABSTRACT

BACKGROUND: In the present study, we aimed to investigate whether early cardiac biomarker alterations and echocardiographic parameters, including left atrial (LA) strain, can predict anthracycline-induced cardiotoxicity (AIC) and thus develop a predictive risk score.Methods and Results: The AIC registry is a prospective, observational cohort study designed to gather serial echocardiographic and biomarker data before and after anthracycline chemotherapy. Cardiotoxicity was defined as a reduction in left ventricular ejection fraction (LVEF) ≥10 percentage points from baseline and <55%. In total, 383 patients (93% women; median age, 57 [46-66] years) completed the 2-year follow-up; 42 (11.0%) patients developed cardiotoxicity (median time to onset, 292 [175-440] days). Increases in cardiac troponin T (TnT) and B-type natriuretic peptide (BNP) and relative reductions in the left ventricular global longitudinal strain (LV GLS) and LA reservoir strain [LASr] at 3 months after anthracycline administration were independently associated with subsequent cardiotoxicity. A risk score containing 2 clinical variables (smoking and prior cardiovascular disease), 2 cardiac biomarkers at 3 months (TnT ≥0.019 ng/mL and BNP ≥31.1 pg/mL), 2 echocardiographic variables at 3 months (relative declines in LV GLS [≥6.5%], and LASr [≥7.5%]) was generated. CONCLUSIONS: Early decline in LASr was independently associated with subsequent cardiotoxicity. The AIC risk score may provide useful prognostication in patients receiving anthracyclines.

ABSTRACT

In patients with end-stage renal disease (ESRD), bloodstream infections and vascular access problems are frequently encountered, and patient management is critical if a cardiac implantable electronic device (CIED) infection develops in a pacing-dependent patient. Here, we describe a case of an ESRD patient with a device infection in whom a leadless pacemaker (LP) implantation from the jugular vein ipsilateral to the dialysis catheter (DC) was successful.

ABSTRACT

BACKGROUND: Dilated cardiomyopathy (DCM) presents with diverse clinical courses, hardly predictable solely by the left ventricular (LV) ejection fraction (EF). Longitudinal strain (LS) offers distinct information from LVEF and exhibits various distribution patterns. This study aimed to evaluate the clinical significance of LS distribution patterns in DCM. METHODS: We studied 139 patients with DCM (LVEF ≤ 35%) who were admitted for heart failure (HF). LS distribution was assessed using a bull's eye map and the relative apical LS index (RapLSI), calculated by dividing apical LS by the sum of basal and mid-LS values. We evaluated the associations of LS distribution with cardiac events (cardiac death, LV assist device implantation, or HF hospitalization) and LV reverse remodeling (LVRR), as indicated by subsequent LVEF changes. RESULTS: Twenty six (19%) and 29 (21%) patients exhibited a pattern of relatively apical impaired or preserved LS (defined by RapLSI < 0.25 or > 0.75, signifying a 50% decrease or increase in apical LS compared to other segments), and the remaining patients exhibited a scattered/homogeneously impaired LS pattern. The proportion of new-onset heart failure and LVEF differed between the three groups. During the median 595-day follow-up, patients with relatively-impaired apical LS had a higher rate of cardiac events (both log-rank p < 0.05) and a lower incidence of LVRR (both p < 0.01) compared to patients with other patterns. RapLSI was significantly associated with cardiac event rates after adjusting for age, sex, and new-onset HF or global LS. CONCLUSION: DCM patients with reduced EF and distinct distribution patterns of impaired LS experienced different outcomes.

ABSTRACT

BACKGROUND: The management of mixed aortic valve disease (MAVD), defined as the concomitant presence of aortic stenosis (AS) and aortic regurgitation, remains a clinical challenging. The present study assessed the impact of transcatheter aortic valve replacement (TAVR) on cardiac geometry and prognosis in patients with MAVD. METHODS AND RESULTS: A retrospective multicenter TAVR registry was conducted, including patients who underwent TAVR for severe symptomatic AS between January 2015 and March 2019. Patients were subdivided into 2 groups according to concomitant presence of moderate or more severe aortic regurgitation as the MAVD group, and with mild or less severe aortic regurgitation as the isolated AS group. The primary outcome was a composite of cardiovascular death and rehospitalization due to cardiovascular causes. A total of 1742 patients (isolated AS, 1522 patients; MAVD, 220 patients) were included (84.0±5.2 years). Although MAVD exhibited significantly larger left ventricular volumes and higher left ventricular mass index at the TAVR procedure than isolated AS (respectively, P<0.001), MAVD showed a greater improvement of left ventricular volumes and left ventricular mass index after TAVR (respectively, P≤0.001). During a median follow-up of 747 days, 301 patients achieved the primary event. The prognosis post-TAVR was comparable between the 2 groups (log-rank P=0.65). Even after adjustment using propensity score matching to reduce the potential bias between the 2 groups, similar results were obtained for the entire cohort. CONCLUSIONS: Despite more advanced cardiac remodeling in MAVD at the time of TAVR compared with isolated AS, a greater improvement of cardiac reverse remodeling was found in MAVD, and the prognosis following TAVR was comparable between the 2 groups.

ABSTRACT

BACKGROUND: Although pulmonary hypertension (PH) and Eisenmenger's syndrome (ES) are common complications in adult congenital heart disease (ACHD), the frequency of diagnostic tests and the incidence of PH/ES in patients with ACHD in Japanese clinical practice are unclear. Therefore, we sought to clarify the frequency of diagnostic tests and incidence of PH/ES in patients with ACHD using the Medical Data Vision (MDV) database, the largest anonymized database of diagnosis procedure combination hospitals in Japan. METHODS: We conducted a retrospective cohort study using the MDV database (April 2008 to December 2021) of patients with ACHD (International Classificaiton of Diseases, 10th revision codes: Q203-204, Q210-213, Q250) aged ≥15 years. The frequency of laboratory/clinical tests and the incidence of PH/ES were calculated. Subgroup analyses were performed for the periods 2008-2015 and 2016-2021. RESULTS: Overall, 28219 ACHD patients were extracted from the MDV database (females 56.3%, males 43.7%; mean ± standard deviation age 44.7 ± 23.5 years). The mean ± standard deviation follow-up period was 2.5 ± 2.7 years. The frequencies of electrocardiography, ultrasonography, brain natriuretic peptide (BNP), N-terminal pro-BNP (NT-proBNP), right heart catheterization, and pulmonary function tests (DLCO) were 2149.8, 1054, 1233, 340, 40.0, and 6.0 per 1000 person-years, respectively. The incidence rate of PH/ES was 32.8 per 1000 person-years. The incidence rate of PH/ES increased from 24.6 to 46.7 per 1000 person-years from 2008-2015 to 2016-2021. CONCLUSION: We have clarified the frequency of diagnostic tests related to PH/ES and the incidence of PH/ES in patients with ACHD in clinical practice in Japan, including non-specialist institutions for PH.

ABSTRACT

AIMS: The anti-inflammatory effects of the xanthine oxidase inhibitor, febuxostat, a urate-lowering agent, have been reported in animal studies. However, the anti-inflammatory effects of urate-lowering therapy and its associated cardiovascular protective effects have not been fully determined in actual clinical practice. This study aimed to investigate the effect of febuxostat on white blood cell (WBC) count in patients with asymptomatic hyperuricemia and to assess for potential correlations between changes in WBC count and inflammatory biomarkers and atherosclerosis in this patient population. METHODS: This was a post hoc subanalysis of the PRIZE study, a multicenter, prospective, randomized, open-label clinical trial. In the PRIZE study, asymptomatic hyperuricemia patients were randomized to febuxostat group or control group with non-pharmacological therapy and evaluated the effect on vascular. The primary endpoints of this study were the assessment of the time course of WBC count over 24 months and its changes from baseline. Correlations of WBC count with high-sensitivity C-reactive protein (hs-CRP) and mean common carotid artery (CCA)-IMT were also exploratorily examined in the febuxostat group. RESULTS: A total of 444 patients (febuxostat group, n=223; control group, n=221) with WBC measurements available at baseline and at least one of the follow-up time points of 12 or 24 months, were enrolled. Febuxostat modestly, but significantly, reduced WBC counts at 12 and 24 months compared with the baseline levels (P=0.002 and P=0.026, respectively). Notably, the WBC count in the febuxostat group at 12 and 24 months was significantly lower than that in the control group (P=0.007 and P=0.023, respectively). The changes in WBC count were associated with those of hs-CRP (P=0.038), but not with CCA-IMT (P=0.727). CONCLUSIONS: Febuxostat therapy for 24 months modestly, but significantly, decreased WBC count in patients with asymptomatic hyperuricemia. This might potentially reflect a modest anti-inflammatory action of febuxostat in clinical settings.

ABSTRACT

PURPOSE: Renal congestion is a therapeutic target in congestive heart failure. However, its detailed evaluation in a clinical setting is challenging. This study sought to assess renal congestion impairment using superb microvascular imaging (SMI), a simple and accessible method. METHODS: Dahl salt-sensitive rats, used as a model for congestive heart failure, underwent central venous pressure (CVP) measurements. Renal congestion was evaluated through measurements of renal medullary pressure (RMP) and assessment of renal perfusion using contrast-enhanced ultrasonography at both the early (control group) and heart failure phases (HF group). All rats were assessed with SMI. The region of interest (ROI) was set in interlobular vessels, interlobar vessels, and a combination of these areas. The area ratio was calculated from the color pixel count in the ROI divided by the total pixel count in the ROI. Intrarenal perfusion index (IRPI) was defined as (maximum area ratio-minimum area ratio) / maximum area ratio. RESULTS: There were no significant differences in renal function and left ventricular ejection fraction between the two groups. CVP, time-to-peak (TTP) in the medulla, and RMP were higher in the HF group than in the control group. In the HF group, IRPI, evaluated in the interlobular vessels, was significantly higher than in the control group. IRPI was positively correlated with TTP in the medulla (p = 0.028, R = 0.60) and RMP (p < 0.001, R = 0.84), indicating that IRPI reflected renal congestion. CONCLUSIONS: IRPI is a useful tool for assessing renal congestion in rats with congestive heart failure.

ABSTRACT

A 67-year-old woman with severe aortic stenosis (AS) was transferred to our hospital for large B-cell lymphoma treatment. Because of her high risk of anthracycline-induced cardiotoxicity due to severe AS and low performance status, the patient was initially treated with doxorubicin-free chemotherapy. However, doxorubicin was considered necessary to achieve complete remission. After multidisciplinary team discussions, transcatheter aortic valve replacement (TAVR) was performed without complications. Nine days after TAVR, the patient received the first cycle of anthracycline-containing chemotherapy (R-CHOP). Currently, 12 months after completing 4 cycles of R-CHOP, the patient remains in complete remission without having developed cardiotoxicity.

ABSTRACT

Aims: The aim of this study was to identify phenotypes with potential prognostic significance in aortic stenosis (AS) patients after transcatheter aortic valve replacement (TAVR) through a clustering approach. Methods and results: This multi-centre retrospective study included 1365 patients with severe AS who underwent TAVR between January 2015 and March 2019. Among demographics, laboratory, and echocardiography parameters, 20 variables were selected through dimension reduction and used for unsupervised clustering. Phenotypes and outcomes were compared between clusters. Patients were randomly divided into a derivation cohort (n = 1092: 80%) and a validation cohort (n = 273: 20%). Three clusters with markedly different features were identified. Cluster 1 was associated predominantly with elderly age, a high aortic valve gradient, and left ventricular (LV) hypertrophy; Cluster 2 consisted of preserved LV ejection fraction, larger aortic valve area, and high blood pressure; and Cluster 3 demonstrated tachycardia and low flow/low gradient AS. Adverse outcomes differed significantly among clusters during a median of 2.2 years of follow-up (P < 0.001). After adjustment for clinical and echocardiographic data in a Cox proportional hazards model, Cluster 3 (hazard ratio, 4.18; 95% confidence interval, 1.76-9.94; P = 0.001) was associated with increased risk of adverse outcomes. In sequential Cox models, a model based on clinical data and echocardiographic variables (χ2 = 18.4) was improved by Cluster 3 (χ2 = 31.5; P = 0.001) in the validation cohort. Conclusion: Unsupervised cluster analysis of patients after TAVR revealed three different groups for assessment of prognosis. This provides a new perspective in the categorization of patients after TAVR that considers comorbidities and extravalvular cardiac dysfunction.

ABSTRACT

AIM: There is little information on the relationships of serum small dense low-density lipoprotein cholesterol (sdLDL-C) levels and serum triglyceride (TG) levels with cardiovascular events in patients with coronary artery disease (CAD) and type 2 diabetes mellitus (DM) who are receiving statins. The aim of this study was to evaluate the relationships of serum TG levels and sdLDL-C levels as residual risks for cardiovascular events in patients with CAD and type 2 DM who were being treated with statins. METHODS: The subjects were divided into four groups based on TG levels and sdLDL-C levels: sdLDL-C of <40.0 mg/dL and TG of <150 mg/dL, sdLDL-C of ≥ 40.0 mg/dL and TG of <150 mg/dL, sdLDL-C of <40.0 mg/dL and TG of ≥ 150 mg/dL, and sdLDL-C of ≥ 40.0 mg/dL and TG of ≥ 150 mg/dL. During a median follow-up period of 1419 days, cardiovascular events occurred in 34 patients. RESULTS: The incidences of cardiovascular events were significantly higher in patients with sdLDL-C of ≥ 40.0 mg/dL and TG of <150 mg/dL and in patients with sdLDL-C of ≥ 40.0 mg/dL and TG of ≥ 150 mg/dL, but not in patients with sdLDL-C of <40.0 mg/dL and TG of ≥ 150 mg/dL, than in patients with sdLDL-C of <40.0 mg/dL and TG of <150 mg/dL. CONCLUSIONS: Under the condition of treatment with statins, patients with CAD and type 2 DM who had sdLDL-C levels of ≥ 40.0 mg/dL had a high risk for cardiovascular events even though serum TG levels were controlled at <150 mg/dL.

ABSTRACT

BACKGROUND: The end-of-life (EOL) status, including age at death and treatment details, of patients with adult congenital heart disease (ACHD) remains unclear. This study investigated the EOL status of patients with ACHD using a nationwide Japanese database.Methods and Results: Data on the last hospitalization of 26,438 patients with ACHD aged ≥15 years, admitted between 2013 and 2017, were included. Disease complexity (simple, moderate, or great) was classified using International Classification of Diseases, 10th Revision codes. Of the 853 deaths, 831 patients with classifiable disease complexity were evaluated for EOL status. The median age at death of patients in the simple, moderate, and great disease complexity groups was 77.0, 66.5, and 39.0 years , respectively. The treatments administered before death to patients in the simple, moderate, and great complexity groups included cardiopulmonary resuscitation (30.1%, 35.7%, and 41.9%, respectively), percutaneous cardiopulmonary support (7.2%, 16.5%, and 16.3%, respectively), and mechanical ventilation (58.7%, 72.2%, and 75.6%, respectively). Overall, 70% of patients died outside of specialized facilities, with >25% dying after ≥31 days of hospitalization. CONCLUSIONS: Nationwide data showed that patients with ACHD with greater disease complexity died at a younger age and underwent more invasive treatments before death, with many dying after ≥1 month of hospitalization. Discussing EOL options with patients at the appropriate time is important, particularly for patients with greater disease complexity.

ABSTRACT

Sacubitril/valsartan improves outcomes in patients with heart failure (HF) with reduced ejection fraction. However, the relationship between longitudinal changes in natriuretic peptides and echocardiographic parameters in patients with HF treated with sacubitril/valsartan across the left ventricular ejection fraction (LVEF) range is not fully understood.In patients with HF treated with sacubitril/valsartan, comprehensive data on natriuretic peptides, including atrial natriuretic peptide (ANP), N-terminal pro-brain-type natriuretic peptide (NT-proBNP), BNP, and echocardiography, were measured after 6 months of treatment. We assessed the change in natriuretic peptides and echocardiographic parameters in LVEF classification subgroups.Among 49 patients, the median ANP concentration increased from 55 pg/mL at baseline to 78 pg/mL (P < 0.001). The NT-proBNP concentration decreased from 250 pg/mL to 146 pg/mL (P < 0.001). No significant change was observed in the BNP concentration (P = 0.640). The trajectories of each natriuretic peptide in patients with LVEF > 40% (n = 22) were similar to those in individuals with LVEF ≤ 40% (n = 27). Regardless of LVEF classification, echocardiography at 6 months showed a significant improvement in LVEF, left ventricular end-diastolic volume, and the ratio of early diastolic mitral inflow velocity to early diastolic mitral annulus velocity (E/e'). The reduction in natriuretic peptide concentration was related to LV reverse remodeling and decreased left and right atrial pressures assessed by E/e' and inferior vena cava diameter.Sacubitril/valsartan induced an increase in ANP, a reduction in NT-proBNP, and no change in plasma BNP, regardless of LVEF. It caused LV reverse remodeling, and the natriuretic peptide concentration changes were associated with structural and functional echocardiographic parameters.

ABSTRACT

AIMS: The first-generation radiofrequency HotBalloon (RHB) is a size-adjustable single-shot device used in atrial fibrillation. The energy output is determined by its central temperature and not by its balloon surface temperature (BST), thus limiting its efficacy and safety. Therefore, a second-generation RHB was developed to monitor BST and enable BST-controlled ablation. This animal study aims to evaluate the accuracy of a newly developed BST-monitoring system and validate the optimal BST for ablation. METHODS AND RESULTS: In Protocol 1, thermocapsules were attached to the superior vena cava (SVC) epicardium. The accuracy of BST monitoring was examined during SVC isolation. In Protocol 2, the efficacy and safety of different BST-controlled ablations were examined. In the acute model, electrophysiological and pathological findings were assessed after energy applications with BST at 51, 54, 57, and 60°C. In the chronic model, the lesion durability and pathological findings were assessed 8 weeks after BST-controlled ablation (57 and 60°C). A significant positive correlation was found between the epicardial temperature and the BST-monitoring value (r = 0.98). In the acute model, all target veins were electrically isolated with BST-controlled ablation at ≥57°C (18/18, 100%). In the chronic model, durable lesions were observed in all veins at 60°C, while 44% of the veins showed reconnection at 57°C. In both pathological analyses, significantly greater lesions were observed at 60°C than at 57°C. There were no significant differences in adverse events between the two groups. CONCLUSION: Balloon surface temperature-controlled ablation at 60°C using the second-generation RHB may be optimal for creating durable lesions without compromising safety.

ABSTRACT

The establishment of a strategy for rapid heart recovery in patients with cardiogenic shock is required. Impella is a percutaneous left ventricular (LV) assist device that maintains hemodynamic stability and also causes LV mechanical unloading. However, the timing at which Impella should be started and a systematic strategy after the start of Impella have not been established. We report a representative case of dilated cardiomyopathy requiring catecholamines and intra-aortic balloon pumping (IABP). The hemodynamics were unstable under IABP support, and withdrawal from IABP or catecholamines was considered impossible. However, the exchange of the IABP with Impella CP made it possible to suppress the heart rate with ivabradine, introduce intensive heart failure medication, and discontinue catecholamines. The patient was weaned from Impella 24 days after the start of the first Impella CP. Rapid heart recovery was achieved with favorable outcomes. We present a comprehensive strategy for rapid heart recovery using Impella in a patient with cardiogenic shock.

ABSTRACT

BACKGROUND: The prevalence of adult congenital heart disease (ACHD) is increasing rapidly and in particular, patients who underwent complicated surgeries are reaching their youth and middle age. Therefore, the need for ACHD treatment will increase, but the current medical situation is unknown. In this study we assessed trends in unplanned admissions in patients with ACHD in Japan.Methods and Results: From the Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination, a nationwide claim-based database, we selected patients aged >15 years with CHD defined by the International Classification of Diseases, 10th Revision codes. We identified 39,676 admissions between April 2012 and March 2018; 10,444 (26.3%) were unplanned. Main diagnoses were categorized into 3 degrees of complexity (severe, moderate, and mild) and other. Among unplanned admissions, the proportion of the severe group increased with time. Patients in the mild group were significantly older than those in the moderate and severe groups (median age: 70.0, 39.0, and 32.0 years, respectively). There were 765 deaths during hospitalization (overall mortality rate, 7.3%). The odds ratio of death during admission was significantly higher in patients aged >50 years, especially in the moderate group. CONCLUSIONS: Patients with moderate or severe ACHD tended to experience unplanned admissions at a younger age. In anticipation of greater numbers of new, severe patients, we need to prepare for their increasing medical demands.

ABSTRACT

Background: Recent studies suggested a relationship between Takotsubo syndrome (TTS) and malignancy. However, clinical outcomes of TTS associated with cancer have not been assessed completely. This study was aimed to investigate the outcomes of patients with TTS and cancer. Methods: We performed a systematic review and meta-analysis to evaluate the clinical outcomes of TTS in patients with and without malignancy. We systematically reviewed and analyzed 14 studies (189,210 patients) published in PubMed and Cochrane Library databases until December 2022. The primary outcome was all-cause mortality at the longest follow-up. Results: The prevalence of current or previous malignancy in patients with TTS was 8.7% (16,461 patients). Patients with TTS and malignancy demonstrated a higher risk of mortality at the longest follow-up than those with TTS alone (odds ratio [OR], 2.41; 95% confidence interval [CI]; 1.95-2.98; P < 0.001). Moreover, cancer was significantly associated with an increased risk of in-hospital or 30-day mortality (OR 2.36; 95% CI, 1.67-3.33; P < 0.001), shock (OR 1.42; 95% CI, 1.30-1.55; P < 0.001), mechanical respiratory support (OR 1.68; 95% CI, 1.59-1.77; P < 0.001), arrhythmia (OR 1.27; 95% CI, 1.21-1.34; P < 0.001), and major adverse cardiac events (OR 1.69; 95% CI, 1.18-2.442; P < 0.001). Conclusions: This study revealed significant associations between previous or active cancer and an increased risk of all-cause mortality and in-hospital adverse events in patients with TTS.
