Based on application, the global cardiac catheterization market is segmented into heart attack, coronary vasospasm
, abnormal stress test, and cardiac arrhythmia.
Cardiac symptoms, including chest pain, coronary vasospasm
, angina pectoris, myocardial infarction, acute cardiac failure, and sudden cardiac death associated with subclinical, clinical, acute, or chronic allergic reactions constitute the clinical manifestations of Kounis syndrome.
(23) It has also been reported that SUM provoked coronary vasospasm
in patients with variant angina but not in control subjects, suggesting the coronary constrictory effect of SUM may be more notable in patients with ischemic heart disease.
Dose-limiting toxicities were headache, coronary vasospasm
secondary to allergic reaction following food ingestion: A case of type I variant Kounis syndrome.
Based on our literature review, the authors of this report conclude that this patient likely either had a STEMI related to a transient coronary vasospasm
or myopericarditis, related to an acute infectious colitis that was likely viral in nature.
Although numerous articles on the etiology of ACS in both pediatric and adult age groups exist, the differential diagnosis of Kounis syndrome (KS), Takotsubo cardiomyopathy (TC), and adrenaline-induced coronary vasospasm
can be challenging as all manifest similar cardiac symptoms and ECG and laboratory signs.
All of the above cases that underwent coronary angiography showed no evidence of coronary artery disease; therefore, their myocardial infarctions were attributed to coronary vasospasm
related to SCB use rather than occlusive disease.
The possible pathogenic mechanism of this disease is still not well established, but is thought to be associated with a high level of catecholamine during extreme stress, and it causes coronary vasospasm
and cardiac microcirculatory disorder.
Two patients had arrhythmias (one SVT and one bradycardia), one had reversible cardiomyopathy, and one had acute coronary vasospasm
. Two patients were treated for CA esophagus and one patient for CA nasopharynx and the other for cholangiocarcinoma.
Patients with coronary vasospasm
with thyrotoxicosis typically present with either resting or exertional angina or syncope.
We postulate seizure-induced hypercatecholaminergic-mediated coronary vasospasm
at the mid-RCA as the cause of the STEMI.
