Background: Several cytochrome P450 (CYP) enzyme families have been identified in extra hepatic tissues such as heart, vasculature, kidney, and lung. CYP2C19 localized in vascular smooth muscle and endothelium contributes to the regulation of vascular tone and homeostasis. However, it is unknown whether CYP2C19 genotype is associated with the vascular tonus in patients with VSA. The aim of this study was to examine the impact of CYP2C19 genotype on coronary artery spasm in patients with VSA. Methods: We examined the distribution of CYP2C19 genotype in patients with VSA (n=129) who were diagnosed by intra-coronary acetylcholine infusion test and healthy subjects (n=455) as control group. CYP2C19 genotypes were divided into 3 groups; (1) CYP2C19*1/*1: EM, (2) one loss-of-function allele (*1/*2, *1/*3: IM), and (3) two loss-of-function alleles (*2/*2, *2/*3, *3/*3: PM). Moreover, we measured the level of high-sensitive CRP (hs-CRP) as a degree of low glade inflammation in each group. Results: The ratios of CYP2C19 genotype (EM, IM, and PM) were 30, 42, and 28% in VSA group, and 32, 49, and 19% in control group. In short, PM frequency was significantly higher in VSA than in control (28% vs 19%, P=0.026). In VSA group, the ratios of CYP2C19 genotype were 36, 44, and 20% in male, and 20, 39, and 41% in female, respectively. Briefly, the PM frequency was significantly higher in female than in male (41% vs 20%, P<0.001). Moreover, the level of hs-CRP was significantly higher in VSA group than in control group (0.17±0.367 vs 0.10.±0.240, P=0.02). When patients were stratified by gender, the level of hs-CRP was significantly higher in VSA group in female (0.11±0.198 vs 0.06±0.105, P=0.031) and male (0.20±0.438 vs 0.12±0.277, P=0.044). Multivariate analysis for coronary spasm indicated high age, hypertension, and high level of hs-CRP as predictive factors among all subjects. PM is a predictive factor for coronary spasm in female group only (OR3.1, 95%RI 1.525-6.317, P=0.002), but not in male (OR0.829, 95%RI 0.453-1.518, P=0.543). Conclusion: The CYP2C19 two loss-of-function alleles (PM) and low grade inflammation may be associated with pathophysiology of coronary artery spasm and the regulation of coronary tonus, especially in female.

Rationale: A novel COVID-19 with a severe acute respiratory syndrome or pneumonia had arisen in Wuhan, China in December 2019. Emerging atrial fibrillation in COVID-19 patients is highly significant in cardiovascular medicine. A newly coronary artery spasm in the presentation of COVID-19 infection has certainly a risk impact on both morbidity and mortality of COVID-19 patients. Wavy triple an electrocardiographic sign (Yasser Sign) is an innovated sign of hypocalcaemia linked to tachypnea and acute respiratory distress. Patient concerns: An elderly male COVID-19 patient presented to physician outpatient clinic with bilateral pneumonia, atrial fibrillation, evidence of coronary artery spasm, and Wavy triple an electrocardiographic sign (Yasser Sign). Diagnosis: COVID-19 pneumonia with coronary artery spasm and the Wavy triple an electrocardiographic sign (Yasser Sign). Interventions: Chest CT scan, electrocardiography, oxygenation, and echocardiography. Outcomes: Gradual dramatic clinical, electrocardiographic, and radiological improvement had happened. Lessons: The reversal of electrocardiographic ST-segment depressions in a COVID-19 patient after adding oral nitroglycerine is an indicator for the presence of coronary artery spasm. It signifies the role of the anti-infective drugs, anticoagulants, antiplatelet, and steroids in COVID-19 patients with bilateral pneumonia, AF, coronary artery spasm are effective therapies. The disappearance of AF after initial therapy may a guide for a good prognosis in this case study. The evanescence of Wavy triple ECG sign as a hallmark for the existence of the Movable-weaning phenomenon of hypocalcaemia is recommended for further wide-study.

Ischaemic heart disease comprises a variety of coronary abnormalities, ranging from obstructive atherosclerotic stenoses to functional coronary vasomotor disorders. The latter comprise coronary spasm, as well as coronary microvascular dysfunction. Importantly, structural and functional abnormalities can coexist in a given patient, making it sometimes difficult to determine the underlying cause of angina. Thus, diagnostic algorithms should not only consider the evaluation of atherosclerotic epicardial disease, but also look for the presence of functional coronary disorders. This holds especially true for patients in whom obstructive coronary disease has been excluded, as many of these patients are labelled as having ‘non-cardiac chest pain’. Such an approach may enable the treating physician to adjust the pharmacological therapy more appropriately, in order to improve symptoms and prognosis. Often drug classes such as calcium channel blockers and nitrates are beneficial in these patients. This chapter gives an overview on the current pharmacological management of patients with coronary artery spasm and those suffering from microvascular angina.

Abstract Background Substantial cases of out-of-hospital cardiac arrest (OHCA) due to acute coronary syndrome have been recognized thus far, but there have been few reports about the aetiology of patients with OHCA without the organic heart disease. Especially, coronary artery spasm would be one of the causes of OHCA. Purpose This study aimed to investigate causes of OHCA without the organic heart disease and to investigate the characteristics and angiographic findings of OHCA patients with vasospastic angina (VSA). Methods Between January 2010 and April 2018, 920 patients with OHCA caused by probable or definite cardiovascular disease were transferred to our hospital. Return of spontaneous contraction was successfully achieved in 151 patients, among whom diagnosis was made in 130 patients. First, we analysed the causes of OHCA in these patients. Second, we compared clinical and angiographic characteristics between the VSA group with OHCA (OHCA-VSA) and the VSA group without OHCA (stable VSA; n=72) from our database. Results Among the 130 patients, 95 (73%) had the organic heart disease; 72, acute coronary syndrome; 19, myocardial disease; 2, valvular heart disease; and 1, congenital heart disease. There were 35 patients (27%) without the organic heart disease. Nineteen patients had primary (i.e., Brugada syndrome, QT prolongation) or secondary arrhythmia (i.e. drug adverse effect). Electrocardiogram, coronary angiogram, and LV structure and function were normal in 35 patients. However, there were 16 patients (11%) with VSA defined by Japanese guideline. The OHCA-VSA group was significantly younger (50±14) than the stable VSA group (64±11, P=0.003). The incidence of diffuse-type spasm in the OHCA-VSA group (100%) was significantly higher than that in the stable VSA group (100% vs. 69%, P<0.05). In addition, the incidence of triple-vessel coronary spasm in the OHCA-VSA group was significantly higher than that in the stable VSA group (86% vs. 25%, P=0.003). Conclusion OHCA patients without the organic heart disease had considerable cases of VSA, in addition to primary or secondary arrhythmia. Furthermore, the severity of spasm in the OHCA-VSA group was more serious and extensive than in comparison with the stable VSA group.

Rationale: Tetany is a common, serious, well-established endocrinal and metabolic hypocalcemic disorder. Chest tetany is a novel metabolic term in hypocalcemia characterized by acute severe twisting chest pain. Movable phenomenon (Yasser’s phenomenon) is a new phenomenon that is usually associated with hypocalcemia. oxygenation may have a role in the management of coronary artery spasm. Patient concerns: A middle-aged farmer smoker male patient presented to physician outpatient clinic with tetany, mimic high lateral myocardial infarction, mirror electrocardiographic change, Movable phenomenon (Yasser’s phenomenon), and coronary artery spasm. Diagnosis: Mimic high lateral myocardial infarction in chest tetany with mirror electrocardiographic change, Movable phenomenon (Yasser’s phenomenon), and coronary artery spasm. Interventions: Electrocardiography, oxygenation, IV calcium injection, and echocardiography. Outcomes: Acute dramatic clinical and electrocardiographic improvement had happened. Lessons: The reversal of mirror electrocardiographic change, reversal of ST-segment depression coronary artery spasm, and normalization of Movable phenomenon (Yasser’s phenomenon) after oxygenation. It signifies the role of oxygen in both coronary artery spasm and tetany. Mirror local electrocardiographic change is a novel described expression that may reflect the myocardial polarity in this chest tetany.
