Sympathetic nervous system (SNS), endothelin 1 (ET-1) and angiotensin II (Ang II) are involved in the pathophysiology of acute myocardial infarction (AMI). Valproic acid (VPA) is under study for the treatment against AMI due to its beneficial cardiac effects. However, the vascular effects of VPA on the activation of the SNS, ET-1 and Ang II after AMI are not fully studied.

Since 1968, the United States Transuranium and Uranium Registries (USTUR) has studied the biokinetics and tissue dosimetry of uranium and transuranium elements in nuclear workers. As part of the USTUR collaboration with the Million Person Study (MPS) of Low-Dose Health Effects, radiation dose to different parts of the human heart is being estimated for workers with documented intakes of 239Pu or 226Ra. The study may be expanded for workers with intakes of 238U and other radionuclides.

[Anomalous origin of left circumflex artery from the right sinus of Valsalva and left anterior descending artery with double intramyocardial tract: a rare case of angina].

Article Synopsis
- A rare case of angina was reported involving a patient's anomalous left circumflex artery originating from the right sinus of Valsalva and having a retroaortic course along with double myocardial bridging of the anterior descending artery.
- The "crossed aorta sign" (or "RAC sign") was observed using a modified apical 4-chamber view during transthoracic echocardiography.
- Although the anomaly was suspected during the initial coronary angiography, it was ultimately confirmed through echocardiography and coronary computed tomography angiography.
Electrocardiographic findings for predicting the left anterior descending artery chronic total occlusion in patients with inferior ST-segment elevation myocardial infarction.

In determining the culprit vessel responsible for inferior ST-segment elevation myocardial infarction (STEMI) as either the right coronary artery (RCA) or left circumflex (LCX), the electrocardiographic value has been validated. However, its ability to predict whether inferior STEMI is complicated by left anterior descending artery (LAD) chronic total occlusion remains uncertain. Based on the involvement of arteries other than the culprit vessels, 189 patients with inferior STEMI from our chest pain center were categorized into four groups: LAD occlusion group (n = 20), LAD stenosis > 50% group (n = 116), normal LAD group (n = 27), and other vessel stenosis > 50% group (n = 26).
