About this trial
The goal of this prospective observational study is to investigate to what extent acute exacerbation of chronic obstructive pulmonary disease (AE-COPD) triggers Takotsubo-stunning, and how this affects the outcome for these patients.
The main questions it aims to answer are:
1. What is cumulative incidence of Takotsubo-stunning in patients hospitalized for AE-COPD at Sahlgrenska University Hospital/S (Gothenburg, Sweden)? 2. Among patients hospitalized for AE-COPD at Sahlgrenska University Hospital/S, what is the risk of in-hospital clinical manifestations of acute heart failure in patients with Takotsubo-stunning compared to those without?

Trial groups
Trial outcomes
Primary outcomes
Reversible left ventricular dysfunction (myocardial stunning) according to echocardiography
Echocardiographic signs of myocardial stunning/Takotsubo-stunning at inclusion (day 0) with recovery of left ventricular function at day 1 and/or day 30
Clinical signs of acute heart failure at inclusion (day 0) or day 1 according to the Killip Classification
Acute heart failure will be defined as modified Killip Class \>1, and will be compared between patients with vs without myocardial stunning/Takotsubo-stunning
Secondary outcomes
In-hospital Major Adverse Cardiac Events (MACE)
Defined as nonfatal myocardial infarction, nonfatal stroke or cardiovascular death; at some point during hospitalization. Comparison between patients with versus without myocardial stunning/Takotsubo-stunning.
Admission to intensive care unit (ICU) during index hospitalization
Admission to ICU at any point during hospitalization. Comparison between patients with versus without myocardial stunning/Takotsubo-stunning.
In-hospital death and death within one year
In-hospital death and death within one year. Comparison between patients with versus without myocardial stunning/Takotsubo-stunning.
