Retrospective analysis of complications and survival in patients with acute inferior myocardial infarction accompanied by right ventricular myocardial infarction

Summary

Right ventricular myocardial infarction (RVMI) accompanies about 30–50% of inferior wall myocardial infarction. RVMI is associated with higher rates of cardiogenic shock, atrioventricular block, atrial fibrillation, increased mortality rates. The topic requires a scientific update, as only a few studies have been made on RVMI during the past decade. We aimed to analyse the impact of RVMI on inferior myocardial infarction.

Design and methods: Retrospective study included 310 patients with documented inferior myocardial infarction (with and without RVMI) between January 2013 and January 2014. Data on baseline characteristics, mortality, in-hospital complications: cardiogenic shock and rhythm and conduction disorders was collected.

Results: In 102 (32.9%) patients with inferior myocardial infarction, RVMI was present and 208 (67.1%) cases were without RVMI involvement. RVMI patients had higher rate of rhythm and conduction disturbances than patients without RVMI involvement: atrioventricular block (OR 3.8, 95% CI 2.0–7.1, p < 0.001), atrial fibrillation (OR 1.6, 95% CI 0.9–2.9, p = 0.001), also higher incidence of cardiogenic shock (OR 2.6, 95% CI 1.7–3.9, p < 0.001). Mortality rates after 24 months were higher in RVMI group (OR 1.8, 95% CI 1.2–3.8, p = 0.034). No significant difference was found on in-hospital mortality.

Conclusions: Right ventricular involvement complicates the long-term mortality and outcomes after inferior myocardial infarction. It is related to a higher incidence of in-hospital complications, especially I–III degree AV block and atrial fibrillation. However, influence on long-term mortality needs further investigation.

Neurogenic stress cardiomyopathy following aneurysmal subarachnoid haemorrhage: a literature review

Summary

Neurogenic stress cardiomyopathy (NSC) is defined as transient cardiac dysfunction occurring after primary brain injury, such as aneurysmal subarachnoid haemorrhage, and characterised by left ventricular systolic dysfunction with reduced ejection fraction and abnormalities of regional wall motion. It may also be suspected if elevated levels of cardiac biomarkers and ECG abnormalities are present. It is a reversible condition with favourable long-term prognosis if diagnosed and treated timely, however, NSC is associated with higher rates of early mortality and complications, including pulmonary oedema, cardiogenic shock, delayed cerebral ischaemia. Early diagnosis of the NSC is important in order to prevent these complications and reduce mortality. Management of the NSC is complicated and a multidisciplinary approach is usually required.
