Lipoprotein(a)-associated thrombus formation and plaque healing in acute coronary syndromes: insights from optical coherence tomography

Yusaku Shibata, Osamu Kurihara, Nobuaki Kobayashi, Fumitaka Okajima et autres

BACKGROUND: Elevated lipoprotein(a) levels are associated with myocardial infarction; however, in-vivo evidence linking lipoprotein(a) to intracoronary thrombosis remains limited. We evaluated phase-specific lipoprotein(a) levels during the hyperacute, acute, and stable phases of acute coronary syndrome and their associations with angiographic and optical …

Cardiac rupture due to Takotsubo syndrome complicated by a myocardial bridge: a case series

Kakeru Ishihara, Hideki Miyachi, Takeshi Yamamoto, Kuniya Asai

Background: Takotsubo syndrome is characterized by transient left ventricular systolic dysfunction, without obstructive coronary artery disease. Myocardial bridge, where a coronary artery courses intramurally, may provoke ischaemia and trigger Takotsubo syndrome. Although both conditions typically have favourable outcomes, we encountered two cases …

Contribution of First Contact With a Cardiologist to the Door-to-Cardiac Catheterization Laboratory Time in Patients With Acute Myocardial Infarction Complicated by Cardiogenic Shock ― Data From K-ACTIVE ―

Toshinori Ko, Yusuke Hosokawa, Kuniya Asai, Atsuo Maeda et autres

BACKGROUND: Current guidelines recommend early revascularization in patients with cardiogenic shock (CS) following acute myocardial infarction (AMI). However, guideline-recommended first medical contact-to-device times is reportedly achieved in only 40% of patients. METHODS AND RESULTS: We retrospectively analyzed 369 patients with AMI complicated …
