Routine Stress Testing After PCI in Patients With and Without Acute Coronary Syndrome: A Secondary Analysis of the POST-PCI Randomized Clinical Trial.

Importance: The appropriate follow-up surveillance strategy for patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI) remains unknown.

Objective: To assess clinical outcomes in patients with and without ACS who have undergone high-risk PCI according to a follow-up strategy of routine stress testing at 12 months after PCI vs standard care alone.

Design, Setting, And Participants: The POST-PCI (Pragmatic Trial Comparing Symptom-Oriented vs Routine Stress Testing in High-Risk Patients Undergoing Percutaneous Coronary Intervention) trial was a randomized clinical trial that compared follow-up strategies of routine functional testing vs standard care alone 12 months after high-risk PCI.

[Hemodynamic Changes in Chronic Liver Disease].

Chronic liver disease causes hemodynamic changes in the body depending on the degree of progression. These hemodynamic changes begin with splanchnic vasodilation, with complications beginning to appear as the hyperdynamic changes occur. As chronic liver disease progresses, increased splanchnic vasodilation and hyperdynamic changes worsen portal hypertension and help cause or worsen chronic liver disease complications, such as ascites.

Differential Impact of Degree of Hypertension on Subclinical Coronary Atherosclerosis in Asymptomatic Subjects With and Without Diabetes Mellitus.

This study sought to evaluate the association between the degree of hypertension and subclinical coronary atherosclerosis in asymptomatic subjects with and without diabetes mellitus (DM). We retrospectively analyzed 7,352 asymptomatic subjects (mean age 52.8 ± 7.

Impact of COVID-19 on Heart Failure Patients in South Korea.

Cardiovascular diseases can affect the clinical course of coronavirus disease 2019 (COVID-19); however, evaluation of COVID-19 contribution to prognosis for each individual disease, such as heart failure, is lacking in South Korea. Therefore, this study aimed to investigate COVID-19 patients with heart failure by matching them with patients with heart failure only and those with COVID-19 only. We performed a nationwide population-based retrospective study using data from the National Health Insurance System.

Association between oral health and incidence of pneumonia: a population-based cohort study from Korea.

Pneumonia is related to oral health of the elderly and intensive care unit patients. However, studies on the relationship between overall oral health and pneumonia in the general population have been limited. The purpose of this study was to investigate the association between oral health and pneumonia using a nationwide population-based Korean cohort database.
