AI Article Synopsis
- The study examined the usefulness of Dobutamine stress echocardiography (DSE) for predicting outcomes in 393 patients without angina after coronary revascularization.
- It found that detecting myocardial ischemia during DSE significantly increased the risk predictions for both all-cause death (hazard ratio 3.5) and cardiac death (hazard ratio 4.2).
- The results suggest that myocardial ischemia is an important independent factor for assessing long-term mortality risk in these patients, even when considering other clinical information.
Article Abstract
The clinical utility of stress testing in patients without angina pectoris after revascularization has been questioned. Dobutamine stress echocardiography (DSE) is an established technique for detection of myocardial ischemia and cardiac risk stratification. We studied the prognostic value of DSE in 393 patients without typical angina pectoris after coronary revascularization. Ischemia was incremental to clinical data in predicting all-cause death (hazard ratio 3.5, 95% confidence interval 1.8 to 6.7) and cardiac death (hazard ratio 4.2, 95% confidence interval 1.8 to 9.8). In conclusion, myocardial ischemia during DSE is independently associated with an increased risk of all-cause mortality and cardiac death in these patients after adjustment for clinical data.

The triglyceride to high density lipoprotein cholesterol (TG/HDL-C) ratio has been consistently linked with the risk of coronary heart disease (CHD). Nevertheless, there is a paucity of studies focusing on acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) or experiencing bleeding events. The study encompassed 17,643 ACS participants who underwent PCI.

Fine particulate matter has been linked with acute coronary syndrome. Nevertheless, the key constituents remain unclear. Here, we conduct a nationwide case-crossover study in China during 2015-2021 to quantify the associations between fine particulate matter constituents (organic matter, black carbon, nitrate, sulfate, and ammonium) and acute coronary syndrome, and to identify the critical contributors.

The influence of the mitochondrial control system on ischemic heart disease has become a major focus of current research. Mitophagy, as a very crucial part of the mitochondrial control system, plays a special role in ischemic heart disease, unlike mitochondrial dynamics. The published reviews have not explored in detail the unique function of mitophagy in ischemic heart disease, therefore, the aim of this paper is to summarize how mitophagy regulates the progression of ischemic heart disease.

Cardiogenic shock (CS) in women is a serious cardiovascular (CV) event associated with a high mortality rate. Non-ischemic etiologies are the most common etiologies in women, such as stress-induced cardiomyopathy, peripartum/postpartum cardiomyopathy, heart failure-related CS, or CS due to myocarditis or valvular heart disease. Although not being the most common etiology in women, acute myocardial infarction is still an important one.

Kawasaki disease (KD) is an inflammatory condition more common in children but rare in adults, where diagnosis can be challenging due to nonspecific symptoms. Early recognition is essential to prevent severe complications. We present the case of a 26-year-old male with adult-onset KD who initially presented with vague symptoms, resulting in diagnostic delays.
