Cardiogenic shock in cancer

Investigating the effect of cancer medication in the development of Takotsubo cardiomyopathy

Takotsubo cardiomyopathy (TCM) is a cardiac condition that is usually characterized by sudden heart failure (HF) or chest pain that resembles acute coronary syndrome (ACS). It is identified by severe systolic dysfunction of the left ventricle (LV) and can be caused by physical, medical, or emotional stress. The pathophysiological mechanisms leading to TCM have not yet been clearly determined. TCM is a complex condition to diagnose and may go undetected during cancer treatment due to the wide variety of cardiotoxic effects associated with antineoplastic therapies. Consequently, timely identification and effective treatment are critical to enhancing the prognosis. Nevertheless, TCM is a more prevalent condition in oncology than was previously believed; therefore, clinicians who treat cancer patients should consider it in their differential diagnosis. The purpose of this manuscript is to provide physicians with a summary of the available evidence regarding the ramifications of the association between TCM and cancer to aid in improving patient management.

Outcomes of Patients With Cancer With Myocardial Infarction-Associated Cardiogenic Shock Managed With Mechanical Circulatory Support

Background

Cardiogenic shock (CS) is the leading cause of death among patients with acute myocardial infarction (AMI) and is managed with temporary mechanical circulatory support (tMCS) in advanced cases. Patients with cancer are at high risk of AMI and CS. However, outcomes of patients with cancer and AMI-CS managed with tMCS have not been rigorously studied.

Methods

Adult patients with AMI-CS managed with tMCS from 2006 to 2018 with and without cancer were identified using the National Inpatient Sample. Propensity score matching (PSM) was performed for variables associated with cancer. Primary outcome was in-hospital death, and secondary outcomes were major bleeding and thrombotic complications.

Results

After PSM, 1287 patients with cancer were matched with 12,870 patients without cancer. There was an increasing temporal trend for prevalence of cancer among patients admitted with AMI-CS managed with tMCS (P trend < .001). After PSM, there was no difference in in-hospital death (odds ratio [OR], 1.00; 95% CI, 0.88-1.13) or thrombotic complications (OR, 1.10; 95% CI, 0.91-1.34) between patients with and without cancer. Patients with cancer had a higher risk of major bleeding (OR, 1.29; 95% CI, 1.15-1.46).

Conclusions

Among patients with AMI-CS managed with tMCS, cancer is becoming increasingly frequent and associated with increased risk of major bleeding, although there was no difference in in-hospital death. Further studies are needed to further characterize outcomes, and inclusion of patients with cancer in trials of tMCS is needed.

Characteristics, management, and outcomes of active cancer patients with cardiogenic shock

AIMS

Characteristics, management, and outcomes of patients with active cancer admitted for cardiogenic shock remain largely unknown. This study aimed to address this issue and identify the determinants of 30-day and 1-year mortality in a large cardiogenic shock cohort of all aetiologies.

METHODS AND RESULTS

FRENSHOCK is a prospective multicenter observational registry conducted in French critical care units between April and October 2016. 'Active cancer' was defined as a malignancy diagnosed within the previous weeks with planned or ongoing anticancer therapy. Among the 772 enrolled patients (mean age 65.7 ± 14.9 years; 71.5% male), 51 (6.6%) had active cancer. Among them, the main cancer types were solid cancers (60.8%), and hematological malignancies (27.5%). Solid cancers were mainly urogenital (21.6%), gastrointestinal (15.7%), and lung cancer (9.8%). Medical history, clinical presentation, and baseline echocardiography were almost the same between groups. In-hospital management significantly differed: patients with cancers received more catecholamines or inotropes (norepinephrine 72% vs. 52%, P = 0.005 and norepinephrine-dobutamine combination 64.7% vs. 44.5%, P = 0.005), but had less mechanical circulatory support (5.9% vs. 19.5%, P = 0.016). They presented a similar 30-day mortality rate (29% vs. 26%) but a significantly higher mortality at 1-year (70.6% vs. 45.2%, P < 0.001). In multivariable analysis, active cancer was not associated with 30-day mortality but was significantly associated with 1-year mortality in 30-day survivors [HR 3.61 (1.29-10.11), P = 0.015].

CONCLUSION

Active cancer patients accounted for almost 7% of all cases of cardiogenic shock. Early mortality was the same regardless of active cancer or not, whereas long-term mortality was significantly increased in patients with active cancer.

The role of temporary mechanical circulatory support in de novo heart failure syndromes with cardiogenic shock: A contemporary review

Cardiogenic shock (CS) is a complex clinical syndrome with a high mortality rate. It can occur to due to multiple etiologies of cardiovascular disease and is phenotypically heterogeneous. Acute myocardial infarction-related CS (AMI-CS) has historically been the most prevalent cause, and thus, research and guidance have focused primarily on this. Recent data suggest that the burden of non-ischemic CS is increasing in the population of patents requiring intensive care admission. There is, however, a paucity of data and guidelines to inform the management of these patients who fall into two broad groups: those with existing heart failure and CS and those with no known history of heart failure who present with "de novo" CS. The use of temporary mechanical circulatory support (MCS) has expanded across all etiologies, despite its high cost, resource intensity, complication rates, and lack of high-quality outcome data. Herein, we discuss the currently available evidence on the role of MCS in the management of patients with de novo CS to include fulminant myocarditis, right ventricular (RV) failure, Takotsubo syndrome, post-partum cardiomyopathy, and CS due to valve lesions and other cardiomyopathies.

Evaluation and management of cancer patients presenting with acute cardiovascular disease: a Clinical Consensus Statement of the Acute CardioVascular Care Association (ACVC) and the ESC council of Cardio-Oncology—part 2: acute heart failure, acute myocardial diseases, acute venous thromboembolic diseases, and acute arrhythmias

Advances in treatment, common cardiovascular (CV) risk factors and the ageing of the population have led to an increasing number of cancer patients presenting with acute CV diseases. These events may be related to cancer itself or cancer treatment. Acute cardiac care specialists must be aware of these acute CV complications and be able to manage them. This may require an individualized and multidisciplinary approach. The management of acute coronary syndromes and acute pericardial diseases in cancer patients was covered in part 1 of a clinical consensus document. This second part focusses on acute heart failure, acute myocardial diseases, venous thromboembolic diseases and acute arrhythmias.

Impact of Active and Historical Cancers on the Management and Outcomes of Acute Myocardial Infarction Complicating Cardiogenic Shock

BACKGROUND

There are limited data on the outcomes of acute myocardial infarction-cardiogenic shock (AMI-CS) in patients with concomitant cancer.

METHODS

A retrospective cohort of adult AMI-CS admissions was identified from the National Inpatient Sample (2000-2017) and stratified by active cancer, historical cancer, and no cancer. Outcomes of interest included in-hospital mortality, use of coronary angiography, use of percutaneous coronary intervention, do-not-resuscitate status, palliative care use, hospitalization costs, and hospital length of stay.

RESULTS

Of the 557,974 AMI-CS admissions during this 18-year period, active and historical cancers were noted in 14,826 (2.6%) and 27,073 (4.8%), respectively. From 2000 to 2017, there was a decline in active cancers (adjusted odds ratio, 0.70 [95% CI, 0.63-0.79]; P &lt; .001) and an increase in historical cancer (adjusted odds ratio, 2.06 [95% CI, 1.89-2.25]; P &lt; .001). Compared with patients with no cancer, patients with active and historical cancer received less-frequent coronary angiography (57%, 67%, and 70%, respectively) and percutaneous coronary intervention (40%, 47%, and 49%%, respectively) and had higher do-not-resuscitate status (13%, 15%, 7%%, respectively) and palliative care use (12%, 10%, 6%%, respectively) (P &lt; .001). Compared with those without cancer, higher in-hospital mortality was found in admissions with active cancer (45.9% vs 37.0%; adjusted odds ratio, 1.29 [95% CI, 1.24-1.34]; P &lt; .001) but not historical cancer (40.1% vs 37.0%; adjusted odds ratio, 1.01 [95% CI, 0.98-1.04]; P = .39). AMI-CS admissions with cancer had a shorter hospitalization duration and lower costs (all P &lt; .001).

CONCLUSION

Concomitant cancer was associated with less use of guideline-directed procedures. Active, but not historical, cancer was associated with higher mortality in patients with AMI-CS.

Cardiogenic shock caused by Takotsubo syndrome complicated with severe anxiety: A case report and literature review

RATIONALE

Takotsubo syndrome (TTS) is characterized by transient and reversible left ventricular systolic dysfunction, which are often associated with acute physical or emotional stressors. Cancer is one of the comorbidities in TTS, and TTS is even considered as a paraneoplastic syndrome, but its mechanism remains unclear. We report a patient in whom cancer and untreated mental disorders triggered TTS.

PATIENT CONCERNS

A 59-year-old man was transferred to the Department of Cardiology because of acute onset of severe chest pain and dyspnea before cystoscopy. He presented with hematuria, had been diagnosed with a high-grade urothelial bladder cancer, and underwent transurethral resection of bladder tumors 4 months previously. He had severe anxiety regarding recurrence and death from cancer, especially after the hematuria recurred.

DIAGNOSIS

TTS and severe anxiety.

INTERVENTIONS

The results of coronary angiography, a left ventriculogram, echocardiography, and the clinical outcome led to the diagnosis of TTS. The patient was treated with extracorporeal membrane oxygenation support, mechanical ventilation, and drugs for heart failure and anxiety.

OUTCOMES

Echocardiography showed normal wall motion on day 6 of symptom onset. Six months after symptom onset, the anxiety score was reduced from 12 to 11, and the patient had no episodes of any discomfort, and no evidence of cancer recurrence was observed.

LESSONS

Patients with cancer and TTS have a higher level of stress, and physicians need to pay more attention to early screening and early treatment of mental disorders in these patients. Prompt and effective multidisciplinary treatment, including psychological counseling and antianxiety drugs, can improve the prognosis in such cases.

[Infections as oncologic emergencies]

Background

Patients with oncologic diseases, particularly those with hematologic malignancies, are at an increased risk of common infections and unique treatment-related complications with high mortality and morbidity. The annual incidence and prevalence of cancer in Germany is rising. Although modern treatments have generally led to improved survival, increasing age, comorbidities, and frailty of the patients require multidisciplinary strategies for handling complex therapeutic concepts and treatment of the associated complications.

Methods

A selective literature search and guidelines from the European Society for Medical Oncology (ESMO), the German Society of Hematology and Medical Oncology (Deutsche Gesellschaft für Hämatologie und Medizinische Onkologie, DGHO), the Infectious Diseases Working Group of the DGHO (Arbeitsgemeinschaft Infektionen in der Hämatologie und Onkologie, AGIHO), and the American Society of Clinical Oncology (ASCO) formed the basis of this study.

Conclusion

Recognition of severe infections in cancer patients and their discrimination from treatment-associated complications is a challenge. Neutropenic fever is the most frequent infectious emergency in oncology. Early empiric treatment with broad-spectrum antibiotics and escalated diagnostic strategies are needed to successfully treat this vulnerable patient group. In this article, a range of potentially life-threatening infections in immunocompromised patients are discussed.

[Infections as oncologic emergencies]

Hintergrund

Patienten mit onkologischen Erkrankungen, insbesondere mit hämatologischen Neoplasien, haben ein erhöhtes Risiko für allgemeine Infektionen und spezielle therapieassoziierte Komplikationen mit hoher Morbidität und Mortalität. Die jährliche Inzidenz und Prävalenz für Krebserkrankungen steigt in Deutschland. Moderne Therapieverfahren haben zu einem verbesserten Überleben geführt, jedoch erfordern steigendes Alter, Komorbiditäten und Gebrechlichkeit der Patienten multidisziplinäre Strategien zur Durchführung komplexer Therapiekonzepte und zur Behandlung von deren Komplikationen.

Methode

Eine selektive Literaturrecherche sowie die Leitlinien der European Society for Medical Oncology (ESMO), der Deutschen Gesellschaft für Hämatologie und Medizinische Onkologie (DGHO), der Arbeitsgemeinschaft Infektionen in der Hämatologie und Onkologie der DGHO (AGIHO) und der American Society of Clinical Oncology (ASCO) sind die Grundlage für den vorliegenden Artikel.

Schlussfolgerungen

Das Erkennen schwerer Infektionen bei Krebspatienten und deren Unterscheidung von therapieassoziierten Komplikationen stellt eine Herausforderung für den behandelnden Arzt dar. Neutropenisches Fieber ist der häufigste infektiologische Notfall in der Onkologie. Frühzeitige empirische Therapie mit Breitspektrumantibiotika und eskalierende diagnostische Maßnahmen sind notwendig für die erfolgreiche Therapie dieser Risikogruppe. In diesem Beitrag wird eine Reihe von lebensbedrohlichen Infektionen bei immunkompromittierten Patienten diskutiert.
