Abstract:RATIONALE: Vasospastic angina is caused by sudden occlusive vasoconstriction of a segment of an epicardial artery, with transient ST-segment elevation on electrocardiography. Brugada Syndrome is an inherited arrhythmogenic cardiac disorder with a diagnostic electrocardiography characterized by coved-type ST-segment elevation in right precordial leads (V1-V3). Those two diseases usually have no correlation. In this report, we discuss an interesting case of a patient who was diagnosed as vasospastic angina according to his coronary angiography, but his electrocardiography showed a Brugada-like ST-segment elevation. PATIENT CONCERNS: Our patient had a 9-month history of temporary but progressive substernal burning sensation with acid bilges of shoulders and arms, as well as profuse sweating at night. DIAGNOSES: Although he had no abnormal laboratory test result, no dysfunctional recorded echocardiogram or documented arrhythmia after being admitted to the hospital, his electrocardiography showed a Brugada-like ST-segment elevation. The coronary angiography result confirmed a diagnosis of vasospastic angina. INTERVENTIONS: The patient was prescribed diltiazem, aspirin, isosorbide mononitrate and rosuvastatin and was strongly advised to quit cigarettes and alcohol. OUTCOMES: Follow-up at half a year turned out well. LESSONS: This case links Brugada syndrome to coronary vasospasm. They may share similar mechanisms. Provocation test and gene test needs to be ran to distinguish both. Long-term follow-up is essential for it may bring a warning sign for life threatening ventricular arrhythmias.

Abstract:BACKGROUND: Coronary vasomotor dysfunction is an important mechanism for angina in patients with unobstructed coronary arteries. OBJECTIVES: The purpose of this study was to determine sex differences in the prevalence and clinical presentation of vasomotor dysfunction in a European population and to examine sex differences in the dose of acetylcholine leading to a positive acetylcholine provocation test (ACH test). METHODS: Between 2007 and 2014, we included 1,379 consecutive patients with stable angina, unobstructed coronaries and ACH test performed for epicardial vasospasm or coronary microvascular dysfunction (CMD) due to microvascular spasm. The predictive value of sex, risk factors, symptoms, and noninvasive test results was analyzed by means of logistic regression. RESULTS: The mean patient age was 62 years, and 42% were male. There were 813 patients (59%) with a pathological ACH test, 33% for CMD and 26% for epicardial vasospasm. A pathological test was more common in females (70% vs. 43%; p < 0.001). In a multivariable logistic regression model the sex difference was statistically significant with a female-male odds ratio for CMD and epicardial vasospasm of 4.2 (95% confidence interval: 3.1 to 5.5; p < 0.001) and 2.3 (95% confidence interval: 1.7 to 3.1; p < 0.001), respectively. Effort-related symptoms, but neither risk factors nor noninvasive stress tests, contributed to predicting a pathological test. Female patients were more sensitive to acetylcholine with vasomotor dysfunction occurring at lower ACH doses compared with male patients. CONCLUSIONS: Vasomotor dysfunction is frequent in patients with angina and unobstructed coronaries in a European population. Female patients have a higher prevalence of vasomotor dysfunction (especially CMD) compared with male patients. A pathological ACH test was observed at lower ACH doses in women compared with men.

Abstract:Patients with microvascular angina are characterized by angina pectoris with proof of myocardial ischemia in the absence of any relevant epicardial stenosis and without myocardial disease (type 1 coronary microvascular dysfunction according to Crea and Camici). Structural and functional alterations of the coronary microvessels (diameter < 500 µm) are the reason for this phenomenon. Frequently such alterations are associated with cardiovascular risk factors. Patients with angina pectoris without epicardial stenoses represent for 10 - 50 % of all patients undergoing coronary angiography depending on the clinical presentation. Diagnostic approaches include non-invasive (e. g. combination of coronary CT-angiography and positron emission tomography/echo Doppler-based coronary flow reserve measurements) as well as invasive procedures (coronary flow reserve measurements in response to adenosine, intracoronary acetylcholine testing). Pharmacological treatment of these patients is often challenging and should be based on the characterization of the underlying mechanisms. Moreover, strict risk factor control and individually titrated combinations of antianginal substances (e. g. beta blockers, calcium channel blockers, nitrates, ranolazine, ivabradine etc.) are recommended.

Language:eng
Abstract:RATIONALE: Although transient reduction in the left ventricular ejection fraction is characteristic of Takotsubo cardiomyopathy, little is known about the time-course changes of myocardial deformation in coronary vasospasm-related Takotsubo cardiomyopathy. PATIENT CONCERNS: We retrospectively analyzed the time-course changes in left ventricle, right ventricle, and left atrium strain values in a patient with coronary vasospasm-related Takotsubo cardiomyopathy. We found that not only left ventricular strain but also left atrial strain was abnormal during acute Takotsubo cardiomyopathy due to coronary vasospasm. Right ventricular free wall strain was normal. DIAGNOSES: Coronary vasospasm-related Takotsubo cardiomyopathy. INTERVENTIONS: A serial echocardiographic study. OUTCOMES: The left ventricular strain was still subnormal despite a normalized left ventricular ejection fraction 2 months later. The left atrial strain was normal when the left ventricular ejection fraction normalized. LESSONS: From this limited experience, it is suggested that echocardiographic myocardial deformation analysis can provide more information than the standard ejection fraction in evaluating myocardial contractile function.

Title:An interesting implantable cardioverter defibrillator treatment for lethal ventricular arrhythmias caused by coronary artery spasm: A case report.

Language:eng
Abstract:RATIONALE: Coronary artery spasm (CAS) could cause serious lethal ventricular arrhythmias. While implantable cardioverter defibrillators (ICDs) have been recommend for secondary prevention of sudden cardiac death related to lethal ventricular arrhythmias. However, in resuscitated sudden cardiac death caused by CAS, the effect of ICD is still not well clear. PATIENT CONCERNS: A 60-year-old male presented with 2 episodes of syncope. Coronary angiography showed normal coronary arteries. Twenty-four hour Holter electrocardiograms revealed that there were repeatedly transient marked ST segment elevation in the all leads except avR lead, junctional rhythm, and subsequently nonsustained ventricular tachycardia. DIAGNOSES: Ischemic-induced lethal ventricular arrhythmias caused by CAS. INTERVENTIONS: Both calcium channel blocker (diltiazem, 180 mg twice daily) and nitrate (isosorbide dinitrate 40 mg twice daily) were initially administrated, and ICD was subsequently implanted as a secondary prevention. OUTCOMES: In the early stage of CAS, ICD therapy terminated the lethal ventricular arrhythmias. Conversely, after the administration of epinephrine, ICD therapy, even combined with external defibrillation, failed in resuscitating sudden cardiac death. LESSONS: For the sudden cardiac death related to lethal ventricular arrhythmias caused by CAS, ICD therapy is an efficient secondary prevention base on administrating coronary vasodilators. Furthermore, administration of epinephrine should be avoided during cardiorespiratory resuscitation of sudden cardiac death caused by CAS.

Title:Malondialdehyde-Modified Low Density Lipoprotein as Oxidative-Stress Marker in Vasospastic Angina Patients.

Abstract:Vasospastic angina (VSA) is caused by endothelial dysfunction and hypercontraction of vascular smooth muscle cells. Although oxidative-stress can induce endothelial dysfunction, the relationship of VSA and the oxidative-stress marker malondialdehyde-modified low density lipoprotein (MDA-LDL) remains unclear. PURPOSE: Serum MDA-LDL was evaluated in candidate VSA patients.The subjects were 84 patients admitted to our hospital because of chest pain at rest. We stratified the patients into 3 groups; definite VSA, suspected VSA, and unlikely VSA according to a Japanese Circulation Society (JCS) guideline. The patients classified as definite VSA or suspected VSA were considered as "clinical VSA".Forty cases were classified as definite VSA, 35 as suspected VSA, and 9 as unlikely VSA. Thus, clinical VSA was the diagnosis in 75 cases. The patient characteristics showed that the average age of the patients was 60.2 years old (men, 61%). The serum MDA-LDL level of the clinical VSA group (126.3 ± 38.0 U/L) was significantly higher than the unlikely VSA group (98.7 ± 31.1 U/L). Serum MDA-LDL was positively correlated with total cholesterol (T-Chol), lowdensity lipoprotein cholesterol (LDL-C), triglycerides, and fasting blood glucose. Multivariate analysis showed that serum MDA-LDL was the most predictive marker for making a diagnosis of clinical VSA (Odds ratio 1.064, 95% confidence interval 1.014-1.145, P = 0.008). In a population with positive or borderline ECG change, the positive rate in the acetylcholine provocation test was significantly higher in the MDA-LDL higher group compared to the MDA-LDL lower group (81% versus 37%, P = 0.032).: Serum MDA-LDL might be a useful biomarker of VSA and have additional value for the diagnosis of clinical VSA.
