Clinical outcomes and mortality in patients with atrial fibrillation and recently diagnosed lung cancer in oncology outpatient settings.

INTRODUCTION: Our aim was to investigate the prevalence of atrial fibrillation (AF) and recently diagnosed lung cancer in the outpatient oncology clinic and to describe the clinical profile, management and outcomes of this population. METHODS: Among 6984 patients visited at the outpatient oncology clinics attending lung cancer patients in five university hospitals from 2017 to 2019, all consecutive subjects with recently diagnosed (<1 year) disease and AF were retrospectively selected and events in follow up were registered. RESULTS: A total of 269 patients (3.9 % of all attended, 71 ± 8 years, 91 % male) were included. Charlson, CHA2DS2-VASc and HAS-BLED indexes were 6.7 ± 2.9, 2.9 ± 1.5 y 2.5 ± 1.2, respectively. Tumour stage was I, II, III and IV in 11 %, 11 %, 33 % and 45 % of them, respectively. Anticoagulants were prescribed to 226 patients (84 %): direct anticoagulants (n = 99;44 %), low molecular weight heparins (n = 69;30 %) and vitamin K antagonists (n = 58;26 %). After 46 months of maximum follow-up, 186 patients died (69 %). Cumulative incidences of events at 3 years were 3.3 ± 1.3 % for stroke/systemic embolism (n = 7); 8.9 ± 2.2 % for thrombotic events (n = 18); 9.9 ± 2.6 % for major bleeding (n = 16), and 15.9 ± 3,0 % for cardiovascular events (n = 33). In patients with early stages of cancer (I-II), 2-year mortality was significantly higher in those with cardiovascular events or major bleeding (85 % vs 25 %, p = 0.01). CONCLUSION: Nearly 4 % or all outpatients in the oncology clinic attending lung cancer present recently diagnosed disease and AF. Major bleeding and cardiovascular event rates are high in this population, with an impact on mortality in early stages of cancer.

Stratification and management of cardiovascular risk in cancer patients. A consensus document of the SEC, FEC, SEOM, SEOR, SEHH, SEMG, AEEMT, AEEC, and AECC.

Both cancer treatment and survival have significantly improved, but these advances have highlighted the deleterious effects of vascular complications associated with anticancer therapy. This consensus document aims to provide a coordinated, multidisciplinary and practical approach to the stratification, monitoring and treatment of cardiovascular risk in cancer patients. The document is promoted by the Working Group on Cardio Oncology of the Spanish Society of Cardiology (SEC) and was drafted in collaboration with experts from distinct areas of expertise of the SEC and the Spanish Society of Hematology and Hemotherapy (SEHH), the Spanish Society of Medical Oncology (SEOM), the Spanish Society of Radiation Oncology (SEOR), the Spanish Society of General and Family Physicians (SEMG), the Spanish Association of Specialists in Occupational Medicine (AEEMT), the Spanish Association of Cardiovascular Nursing (AEEC), the Spanish Heart Foundation (FEC), and the Spanish Cancer Association (AECC).

Effectiveness of sacubitril-valsartan in cancer patients with heart failure.

AIMS: Current guidelines recommend sacubitril/valsartan for patients with heart failure and reduced left ventricular ejection fraction (LVEF), but there is lack of evidence of its efficacy and safety in cancer therapy-related cardiac dysfunction (CTRCD). Our aim was to analyse the potential benefit of sacubitril/valsartan in patients with CTRCD. METHODS AND RESULTS: We performed a retrospective multicentre registry (HF-COH) in six Spanish hospitals with cardio-oncology clinics including all patients treated with sacubitril/valsartan. Demographic and clinical characteristics and laboratory and echocardiographic data were collected. Median follow-up was 4.6 [1; 11] months. Sixty-seven patients were included (median age was 63 ± 14 years; 64% were female, 87% had at least one cardiovascular risk factor). Median time from anti-cancer therapy to CTRD was 41 [10; 141] months. Breast cancer (45%) and lymphoma (39%) were the most frequent neoplasm, 31% had metastatic disease, and all patients were treated with combination antitumor therapy (70% with anthracyclines). Thirty-nine per cent of patients had received thoracic radiotherapy. Baseline median LVEF was 33 [27; 37], and 21% had atrial fibrillation. Eighty-five per cent were on beta-blocker therapy and 76% on mineralocorticoid receptor antagonists; 90% of the patients were symptomatic NYHA functional class ≥II. Maximal sacubitril/valsartan titration dose was achieved in 8% of patients (50 mg b.i.d.: 60%; 100 mg b.i.d.: 32%). Sacubitril/valsartan was discontinued in four patients (6%). Baseline N-terminal pro-B-type natriuretic peptide levels (1552 pg/mL [692; 3624] vs. 776 [339; 1458]), functional class (2.2 ± 0.6 vs. 1.6 ± 0.6), and LVEF (33% [27; 37] vs. 42 [35; 50]) improved at the end of follow-up (all P values ≤0.01). No significant statistical differences were found in creatinine (0.9 mg/dL [0.7; 1.1] vs. 0.9 [0.7; 1.1]; P = 0.055) or potassium serum levels (4.5 mg/dL [4.1; 4.8] vs. 4.5 [4.2; 4.8]; P = 0.5). Clinical, echocardiographic, and biochemical improvements were found regardless of the achieved sacubitril-valsartan dose (low or medium/high doses). CONCLUSIONS: Our experience suggests that sacubitril/valsartan is well tolerated and improves echocardiographic functional and structural parameters, N-terminal pro-B-type natriuretic peptide levels, and symptomatic status in patients with CTRCD.

A 70-Year-Old Woman With a Prosthetic Mitral Valve and Sudden Chest Pain.

CASE PRESENTATION: A 70-year-old woman presented to the ED with oppressive ongoing chest pain that had lasted for 1 hour and was accompanied by intense sweating. The patient had a previous history of bronchial asthma, severe degenerative mitral regurgitation, and an ostium secundum atrial septal defect that had been treated 6 years ago with a prosthetic mechanical mitral valve, Bicarbon 25, and an atrial septal defect closure. She was being treated with ciclesonide, tiotropium bromide, olodaterol, theophylline, and warfarin, adjusted according to the international normalized ratio. Two weeks before the current event, because of trauma suffered in her leg, her primary care physician changed her treatment to subcutaneous enoxaparin, 80 mg once daily. Considering that her weight was 80 kg and her renal function was normal, the dose of enoxaparin prescribed was subtherapeutic for a mechanical prosthetic valve.

Myocardial stunning identified by using strain/strain rate imaging during dobutamine stress echocardiography in a rare late recurrence of Tako-Tsubo syndrome.

Tako-Tsubo cardiomyopathy affects postmenopausal women and is often associated to emotional or physical stress. It is typically characterized by transient left ventricular apical ballooning with chest pain and, electrocardiographic changes and biochemical markers suggestive of acute coronary syndrome, despite angiographically normal coronary arteriograms. The pathogenesis of the condition is still unknown, but increased catecholamine levels have been postulated as a pathogenic mechanism. Little data exist in the medical literature regarding recurrent events in this disorder. We present here a case of a 62 year-old woman who had a recurrent episode of Tako-Tsubo syndrome 6 years after initial presentation with typical features of the condition. An underlying cause could not be found that could explain the recurrence of this late episode.
