The timing of death in acute pulmonary embolism patients regarding the mortality risk stratification at admission to the hospital.

Background: The management of patients with acute pulmonary embolism (aPE) depends on the severity of aPE. The timing of death in various aPE risk subgroups is only partially known. Methods: 1618 patients with an objectively established aPE diagnosis with computed tomography pulmonary angiography enrolled in the regional PE registry were included in the study. According to ESC criteria, patients were stratified at admission to the hospital in four risk strata. The timing of PE-related and non-PE-related deaths was analyzed regarding mortality risk. Results: PE-related, and non-PE-related hospital death rates were 1.1 % and 1.5 % in low, 1.1 % and 4.8 % in intermediate-low, 8.1 % and 5.9 % in intermediate-high, and 27.7 % and 6.9 % in high-risk groups, respectively. The median time of PE-related and non-PE-related death across the PE mortality risk were: 4 (1.7-7.5) and 7.0 (4-14.7) days in low, 1.5 (1.0-9.5) and 11.5 (2.0-21.0) days in intermediate-low, 4.0 (2.0-9.0) and 9.0 (5.7-18.2) days in intermediate-high, 2.0 (1.0-4.75) and 7.0 (3.0-21.2) days in high-risk subgroups. 48.2 % and 17.1 % of patients who died in the high and intermediate-high risks died during the first hospital day. After the 6th hospitalization day, PE-related deaths were recorded in 43.9 % of deaths from intermediate-high and 17.9 % from high-risk subgroups. Conclusion: PE-related mortality is prominent on the first hospitalization day in high and intermediate-high-risk PE. A substantial proportion of intermediate-high and high-risk patient's PE deaths occurred after the first 6 days of hospitalization.

New-Onset Paroxysmal Atrial Fibrillation in the Setting of Acute Pulmonary Embolism Is Associated with All-Cause Hospital Mortality in Women but Not in Men.

BACKGROUND: Patients with acute pulmonary embolism (PE) may have various types of atrial fibrillation (AF). The role of AF in hemodynamic states and outcomes may differ between men and women. METHODS: In total, 1600 patients (743 males and 857 females) with acute PE were enrolled in this study. The severity of PE was assessed using the European Society of Cardiology (ESC) mortality risk model. Patients were allocated into three groups according to their electrocardiography recordings taken during hospitalization: sinus rhythm, new-onset paroxysmal AF, and persistent/permanent AF. The association between the types of AF and all-cause hospital mortality was tested using regression models and net reclassification index (NRI) and integrated discrimination index (IDI) statistics with respect to sex. RESULTS: There were no differences between the frequencies of the types of AF between men and women: 8.1% vs. 9.1% and 7.5% vs. 7.5% (p = 0.766) for paroxysmal and persistent/permanent AF, respectively. We found that the rates of paroxysmal AF significantly increased across the mortality risk strata in both sexes. Among the types of AF, the presence of paroxysmal AF had a predictive value for all-cause hospital mortality independent of mortality risk and age in women only (adjusted HR, 2.072; 95% CI, 1.274-3.371; p = 0.003). Adding paroxysmal AF to the ESC risk model did not improve the reclassification of patient risk for the prediction of all-cause mortality, but instead enhanced the discriminative power of the existing model in women only (NRI, not significant; IDI, 0.022 (95% CI, 0.004-0.063); p = 0.013). CONCLUSION: The occurrence of paroxysmal AF in female patients with acute PE has predictive value for all-cause hospital mortality independent of age and mortality risk.

Signs and symptoms of acute pulmonary embolism and their predictive value for all-cause hospital death in respect of severity of the disease, age, sex and body mass index: retrospective analysis of the Regional PE Registry (REPER).

BACKGROUND: The incidence of the signs and symptoms of acute pulmonary embolism (PE) according to mortality risk, age and sex has been partly explored. PATIENTS AND METHODS: A total of 1242 patients diagnosed with acute PE and included in the Regional Pulmonary Embolism Registry were enrolled in the study. Patients were classified as low risk, intermediate risk or high risk according to the European Society of Cardiology mortality risk model. The incidence of the signs and symptoms of acute PE at presentation with respect to sex, age, and PE severity was investigated. RESULTS: The incidence of haemoptysis was higher in younger men with intermediate-risk (11.7% vs 7.5% vs 5.9% vs 2.3%; p=0.01) and high-risk PE (13.8% vs 2.5% vs 0.0% vs 3.1%; p=0.031) than in older men and women. The frequency of symptomatic deep vein thrombosis was not significantly different between subgroups. Older women with low-risk PE presented with chest pain less commonly (35.8% vs 55.8% vs 48.8% vs 51.9%, respectively; p=0.023) than men and younger women. However, younger women had a higher incidence of chest pain in the lower-risk PE group than in the intermediate-risk and high-risk PE subgroups (51.9%, 31.4% and 27.8%, respectively; p=0.001). The incidence of dyspnoea (except in older men), syncope and tachycardia increased with the risk of PE in all subgroups (p<0.01). In the low-risk PE group, syncope was present more often in older men and women than in younger patients (15.5% vs 11.3% vs 4.5% vs 4.5%; p=0.009). The incidence of pneumonia was higher in younger men with low-risk PE (31.8% vs<16% in the other subgroups, p<0.001). CONCLUSION: Haemoptysis and pneumonia are prominent features of acute PE in younger men, whereas older patients more frequently have syncope with low-risk PE. Dyspnoea, syncope and tachycardia are symptoms of high-risk PE irrespective of sex and age.

Women have right ventricular infarction more frequently than men.

OBJECTIVE: The objective of the study was to determine whether women significantly have more frequently right ventricular infarction than men. METHODS: The study population consisted of consecutive patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous intervention. The following criteria were used for the diagnosis of right ventricular infarction: ST-segment elevation in one of the right precordial leads V4R-V6R for equal or more than 1 mm together with ST-segment elevation in at least two contiguous inferior leads. The odds ratio for the diagnosis was calculated according to gender. Searching PubMed, nine more relevant studies that used the same criteria for the diagnosis of right ventricular infarction were identified and a metanalysis was conducted. RESULTS: In our group of 517 consecutive patients with STEMI, 32 (23.5%) of 136 women and 42 (11.0%) of 381 men had RVI (odds ratio (OR) = 2.48, 95% confidence interval (CI): 1.49-4.13; P = 0.001). Two hundred and seventy-five patients had inferior STEMI and among them 32 (42.7%) of 75 women and 42 (23.1%) of 182 men, had a right ventricular infarction (OR = 2.48, 95%CI: 1.40-4.40; P= 0.002). In a meta-analysis, a total number of 4,326 patients with inferior STEMI were included. Four hundred and thirty-seven (41.4%) out of 1,056 women and 1,221 (37.3%) out of 3,270 men, had been diagnosed with RVI (OR = 1.27, 95% CI: 1.09-1.48; P = 0.021). CONCLUSION: Right ventricular infarctions occur more frequently in women than in men.

Dynamics of electrocardiographic changes, brain-natriuretic peptide and cortisol levels in a patient with stress (takotsubo) cardiomyopathy--a case report.

INTRODUCTION: Takotsubo cardiomyopathy is a transient acute heart failure syndrome caused by stress that provokes left ventricular mid-apical akinesis and mimics acute coronary syndrome. CASE REPORT: A 66-year-old woman had chest pain and dispnoea a few hours before hospitalization. A sudden emotional stressful event preceded the symptoms. Electrocardiographic abnormalities--precordial ST elevation and modest increase of cardiac troponin mimiced acute myocardial infarction. However, echocardiographic examination showed apical ballooning with markedly diminished left ventricle ejection fraction and the obstruction in the outflow tract of the left ventricle. Coronary angiography at admission showed no coronary stenosis and slower blood flow through the left anterior descending artery. According to anamnesis, echocardiography and coronarography finding we established the diagnosis of stress cardiomyopathy--takotsubo cardiomyopathy. We described in details the slow but dynamic electrocardiographic changes, levels of brain natriuretic peptide, cortisol and echocardiography evolution of disease during a 4-month follow-up till the full recovery. CONCLUSION: Stress (takotsubo) cardiomyopathy--became an important differential diagnosis of acute anterior myocardial infarction and it should be reconsidered every time when emotionally stressed patients with transient-apical akinesis or dyskinesis of the LV are present.
