Aims The aim of this study is to evaluate temporal trends, treatment, and clinical outcomes of patients who present with an acute myocardial infarction (AMI) and have a current or historical diagnosis of cancer, according to cancer type and presence of metastases. Methods and results Data from 6 563 255 patients presenting with an AMI between 2004 and 2014 from the US National Inpatient Sample (NIS) database were analysed. A total of 5 966 955 had no cancer, 186 604 had current cancer, and 409 697 had a historical diagnosis of cancer. Prostate, breast, colon, and lung cancer were the four most common types of cancer. Patients with cancer were older with more comorbidities. Differences in invasive treatment were noted, 43.9% received percutaneous coronary intervention (PCI) in patients without cancer, whilst only 21.0% of patients with lung cancer received PCI. Lung cancer was associated with the highest in-hospital mortality [odds ratio (OR) 2.71, 95% confidence interval (CI) 2.62–2.80], major adverse cardiovascular and cerebrovascular complications (OR 2.38, 95% CI 2.31–2.45), and stroke (OR 1.91, 95% CI 1.80–2.02), while colon cancer was associated with highest risk of bleeding (OR 2.82, 95% CI 2.68–2.98). Irrespective of the type of cancer, presence of metastasis was associated with worse in-hospital outcomes, and historical cancer did not adversely impact on survival (OR 0.90, 95% CI 0.89–0.91). Conclusion A concomitant cancer diagnosis is associated with a conservative medical management strategy for AMI, and worse clinical outcomes, compared to patients without cancer. Survival and clinical outcomes in the context of AMI vary significantly according to the type of cancer and metastasis status. The management of this high-risk group is challenging and requires a multidisciplinary and patient-centred approach to improve their outcomes.

Aims This study aims to examine the temporal trends and outcomes in patients who undergo percutaneous coronary intervention (PCI) with a previous or current diagnosis of cancer, according to cancer type and the presence of metastases. Methods and results Individuals undergoing PCI between 2004 and 2014 in the Nationwide Inpatient Sample were included in the study. Multivariable analyses were used to determine the association between cancer diagnosis and in-hospital mortality and complications. 6 571 034 PCI procedures were included and current and previous cancer rates were 1.8% and 5.8%, respectively. Both rates increased over time and the four most common cancers were prostate, breast, colon, and lung cancer. Patients with a current lung cancer had greater in-hospital mortality (odds ratio (OR) 2.81, 95% confidence interval (95% CI) 2.37–3.34) and any in-hospital complication (OR 1.21, 95% CI 1.10–1.36), while current colon cancer was associated with any complication (OR 2.17, 95% CI 1.90–2.48) and bleeding (OR 3.65, 95% CI 3.07–4.35) but not mortality (OR 1.39, 95% CI 0.99–1.95). A current diagnosis of breast was not significantly associated with either in-hospital mortality or any of the complications studied and prostate cancer was only associated with increased risk of bleeding (OR 1.41, 95% CI 1.20–1.65). A historical diagnosis of lung cancer was independently associated with an increased OR of in-hospital mortality (OR 1.65, 95% CI 1.32–2.05). Conclusions Cancer among patients receiving PCI is common and the prognostic impact of cancer is specific both for the type of cancer, presence of metastases and whether the diagnosis is historical or current. Treatment of patients with a cancer diagnosis should be individualized and involve a close collaboration between cardiologists and oncologists.

Although immune checkpoint inhibitor (ICI) myocarditis carries a high reported mortality, increasing reports of smoldering myocarditis suggest a clinical spectrum of disease. Endomyocardial biopsy (EMB) remains the gold standard for diagnosis of ICI myocarditis, but different pathologic diagnostic criteria exist. The objective of this study was to classify the spectrum of ICI myocarditis and myocardial inflammation by pathology findings on EMB and correlate this with clinical outcomes.

The use of contrast echocardiography in the assessment of cardiac masses has been shown to be helpful in distinguishing tumor from thrombus. Deformation imaging of cardiac tumors has been shown to differentiate better rhabdomyomas from fibromas in pediatric patients. Cardiac MRI (CMR) appears to be helpful in determining whether cardiac tumors are benign or malignant by identifying presence of infiltration, uptake of contrast in first pass perfusion and gadolinium enhancement. Patients with evidence of cardiac metastases by CMR show similar survival to stage IV cancer without cardiac metastases. In our institution, we use a standardized approach for the evaluation of cardiac masses, which includes multimodality imaging in the appropriate clinical context. The autotransplantation surgical technique has shown some promise in improving survival in patients with primary cardiac sarcomas. In our institution, we do not routinely recommend anticoagulation for "tumor-thrombus" in renal cell carcinoma due to risk of bleeding from primary tumor. Cardiac masses are often found incidentally, but sometimes can present with cardiovascular symptoms due to obstruction and valvular dysfunction, which may prompt imaging. It is important to determine whether the mass is a normal variant, imaging artifact, vegetation, thrombus, or tumor. Transthoracic echocardiography is ideally suited to be the initial imaging modality because of the portability, wide availability, lack of radiation, and relatively low cost. The gold standard cardiac imaging technique to distinguish tumor from thrombus is contrast enhanced CMR with prolonged inversion time. Advantages of CMR when compared to echocardiography regarding characterization of cardiac tumors are as follows: larger field of view, better spatial resolution, better tissue characterization, lack of attenuation, and ability to image at any prescribed plane. Primary and secondary cardiac tumors have particular characteristics in echocardiography and CMR. Imaging of cardiac tumors plays an important role in establishing a diagnosis and in planning management.

Rare neuroendocrine tumours (NETs) that most commonly arise in the gastrointestinal tract can lead to carcinoid syndrome and carcinoid heart disease. Patients with carcinoid syndrome present with vasomotor changes, hypermotility of the gastrointestinal system, hypotension and bronchospasm. Medical therapy for carcinoid syndrome, typically with somatostatin analogues, can help control symptoms, inhibit tumour progression and prolong survival. Carcinoid heart disease occurs in more than 50% of these patients and is the initial presentation of carcinoid syndrome in up to 20% of patients. Carcinoid heart disease has characteristic findings of plaque-like deposits composed of smooth muscle cells, myofibroblasts, extracellular matrix and an overlying endothelial layer which can lead to valve dysfunction. Valvular dysfunction can lead to oedema, ascites and right-sided heart failure. Medical therapy of carcinoid heart disease is limited to symptom control and palliation. Valve surgery for carcinoid heart disease should be considered for symptomatic patients with controlled metastatic carcinoid syndrome. A multidisciplinary approach is needed to guide optimal management.

Introduction: Late cardiotoxicity related to radiotherapy (RT) in breast cancer and Hodgkin's lymphoma has been wellreported. However, the relatively higher cardiac dose exposure for esophageal cancer (EC) may result in the earlier onset of cardiac diseases. In this report, we examined the incidence, onset, and long-term survival outcomes of high-grade cardiac events after RT in a large cohort of patients with EC.Methods: Between March 2005 and August 2017, a total of 479 patients with EC from a prospectively maintained institutional database at The University of Texas MD Anderson Cancer Center were analyzed. All patients were treated with either intensity-modulated RT or proton beam therapy, either preoperatively or definitively. We focused on any grade 3 or higher (G3þ) cardiac events according to the Common Terminology Criteria for Adverse Events, version 5.0.Results: G3þ cardiac events occurred in 18% of patients at a median of 7 months with a median follow-up time of 76 months. Preexisting cardiac disease (p ¼ 0.001) and radiation modality (intensity-modulated RT versus proton beam therapy) (p ¼ 0.027) were significantly associated with G3þ cardiac events. Under multivariable analysis, the mean heart dose, particularly of less than 15 Gy, was associated with reduced G3þ events. Furthermore, G3þ cardiac events were associated with worse overall survival (p ¼ 0.041).Conclusions: Severe cardiac events were relatively common in patients with early onset EC after RT, especially those with preexisting cardiac disease and higher radiation doses to the heart. Optimal treatment approaches should be taken to reduce cumulative doses to the heart, especially for patients with preexisting cardiac disease.
