Hemodynamic Stability and Contrast Nephropathy Development in Patients With Acute Myocardial Infarction

We read the article entitled “Contrast-Induced Nephropathy and Long-Term Mortality After Percutaneous Coronary Intervention in Patients with Acute Myocardial Infarction” by Sun et al with interest. They found that contrast-induced nephropathy (CIN) was an independent predictor for long-term mortality, even in patients with a stable hemodynamic status and preserved left ventricular ejection fraction (LVEF). Meanwhile, renal insufficiency played an important role in the prognosis of CIN, and the use of b-blockers was a protective factor. They also proposed that the adverse outcome of CIN did not depend on cardiac function. The LVEF parameter used by the authors in the definition of hemodynamic stability is not sufficient according to current heart failure guidelines. New York Heart Association functional status, volume status, diastolic heart failure, or combined (systolic and diastolic heart failure) heart failure was not mentioned in the text. All of these abovementioned parameters are closely related to the patients’ cardiovascular status. In addition, the development of heart failure is more common in patients with anterior myocardial infarction (MI), but there is no information about MI typing in the text. ORCID iDs
