Objective: Anxiety and depression are risk factors for obstructive coronary artery disease (CAD), but their effects on coronary artery spasm (CAS) remain unestablished. Methods: Patient records in this population-based study were retrospectively collected from the Taiwan National Health Insurance Research Database. Using propensity score matchin...
Article
Objective: Smoking and high-sensitivity C-reactive protein (hs-CRP) are risk factors for coronary artery spasm (CAS), which is characterized by the increased interleukin-6 (IL-6) level and monocyte counts; however, limited data are available regarding the role of cigarette-embedded nicotine in the modulation of monocytic inflammatory activity in C...
Article
Oxidized phospholipids (OxPL) are ubiquitously generated during inflammation, and found on apoptotic cells, OxLDL, and Lp(a). They facilitate uptake of OxLDL by macrophages (Mac) and mediate cellular inflammatory responses. The E06 natural IgM binds to the PC of OxPL, neutralizing biological effects and inhibiting OxLDL uptake by Mac. To determine...

Although asthma increases the risk of cardiovascular disease, little is known about the relation of asthma and its severity to coronary vasospastic angina (CVsA). We hypothesized that asthma contributed to the development of CVsA. Patients in this population-based cohort study were retrospectively collected from the Taiwan National Health Insurance...
Article
Effect of Age, Sex, Smoking, and Inflammation Coronary artery spasm (CAS) is provoked by cold exposure and has circadian variation (1). While seasonal variation with winter and spring peaks occurs in obstructive coronary artery disease (CAD) (2,3), the effect of cold stress with seasonality on CAS is unclear. Age, male sex, smoking, and high-sensit...
Article
Background: Arterial stiffness is a physiologic quantitative value used to measure arterial compliance. It is predictive of coronary atherosclerosis in patients with intermediate to high cardiovascular risk. However, a correlation between arterial stiffness and subclinical coronary atherosclerosis has yet to be established. Therefore, the purpose...

Background: Scarce data are available on hemoglobin and platelet in relation to coronary artery spasm (CAS) development. We sought to determine the roles that high-sensitivity C-reactive protein (hs-CRP), hemoglobin and platelet play in CAS patients. Methods: Patients (337 women and 532 men) undergoing coronary angiography with or without CAS but w...
Article
Background Polyphenol-rich longan seed extract (LSP) is a free radical scavenger and antioxidant. However, the effect of LSP on the growth of human colorectal carcinoma cells (CRC) has not yet been evaluated.
Article
Although inhibition of Rho-associated coiled-coil containing protein kinase (ROCK) has been shown to prevent coronary vasospastic angina (CVA), direct evidence linking ROCK activity and CVA is lacking. Accordingly, we investigated whether ROCK activity is an independent marker for CVA and is altered after treatment with antispastic medications. We...
Article
Coronary vasospasm of the left main coronary artery (LMCA) is a rare condition with potentially devastating consequences. We present 2 patients with LMCA vasospasm-related angina, the first being a 46-year-old woman and the second a 51-year-old woman. Both of them developed ST-segment ischemic changes on treadmill exercise tests. Coronary angiograp...

Coronary vasospasm is a rare diagnosis resulting in sudden arrhythmic cardiac arrest. We report a case of a healthy, non-smoking elderly woman resuscitated from arrhythmic cardiac arrest. She had persistent spontaneous coronary vasospasm, leading to right ventricular myocardial injury and failure, and shock. She responded quickly to intravenous nor...
Article
Coronary vasospasm (CVsp) has been reported to be an inflammatory disease, reflected by elevated high-sensitivity C-reactive protein (hs-CRP). We investigated the interactions among gender, age, hypertension and hs-CRP in patients with CVsp. We retrospectively examined 722 Taiwanese patients with or without CVsp during an 8-year period. None of the...
Article
We hypothesized a possible mechanism for atherosclerosis in which interleukin-6 (IL-6) might affect the endothelial nitric oxide synthase (eNOS)-caveolin-1 interaction and result in decreased nitric oxide bioavailability in the setting of low-grade inflammation. Because eNOS and caveolin-1 are crucial for vascular tone control, we studied the effec...

Of 315 consecutive acute myocardial infarction patients admitted to our institution over a 4-year period, 5 (2 men, 3 women) were suspected of having acute myocarditis. These 5 patients...
Article
Exercise-induced ST-segment elevation is a relatively uncommon problem and occurs more frequently in patients who have had a myocardial infarction. Data is limited on the characteristics of Taiwanese patients without prior myocardial infarction who develop exercise-induced ST-segment elevation. Exercise-induced ST-segment elevation developed in 9 o...
Article
We report on a case of pulsatile femoral veins with a systolic thrill and murmur in a 26-year-old patient who exhibited severe tricuspid regurgitation. The pulsatile nature of the veins may result from the 'ventricularization' of venous pressure with each pressure pulse. The observed systolic thrill and murmur may be due to the systolic reversal of...
