Sueda S, Kohno H. Relationships between more than 90% coronary luminal narrowing induced by ergonovine provocation test and ECG ischemic change as well as chest symptoms. Heart Vessels 2017; 33:95-101. [PMID: 28808762 DOI: 10.1007/s00380-017-1035-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2017] [Accepted: 08/09/2017] [Indexed: 01/27/2023]
Abstract
In the clinic, patients with ≥90% luminal narrowing during ergonovine (ER) testing had variable response. We investigated ischemic findings and chest symptoms in patients with ≥90% luminal narrowing when performing ER tests, retrospectively. We performed 1210 ER tests over 26 years (1991-2016). We analyzed chest symptoms and positive ischemic ECG changes during ER tests. More than 90% luminal narrowing was found in 352 patients (29.1%) including 211 patients in the right coronary artery (RCA) and 217 patients in the left coronary artery (LCA). Chest symptom was observed in 290 patients (82.4%) including 162 patients in the RCA and 179 patients in the LCA. ST elevation was found in 154 patients including 98 in the RCA and 73 patients in the LCA, while ST depression was recognized in 81 patients including 38 patients in the RCA and 62 patients in the LCA. Two-third of patients with ≥90% luminal narrowing had significant ischemic ECG changes, whereas 60.5% of patients with ≥90% luminal narrowing complained usual chest pain accompanied with significant ischemic ECG changes. Unusual chest symptom was complained in 7.1% of patients with ≥90% luminal narrowing. Neither chest symptom nor ECG changes was found in 48 patients (13.6%) with ≥90% luminal narrowing. We should understand some limitation to diagnose positive coronary spasm during ER tests.

The real world in the clinic before and after the establishment of guidelines for coronary artery spasm: a questionnaire for members of the Japanese Cine-angio Association.

Abstract
We investigated the clinical situations and the present knowledge of Japanese cardiologists about coronary artery spasm before and after the establishment of guidelines for this condition in the real world. A questionnaire was developed regarding the number of cases of coronary angiography, percutaneous coronary intervention, and invasive/non-invasive spasm provocation tests before (2008) and after (2014) the establishment of the Japanese Circulation Society (JCS) guidelines for coronary artery spasm and the status of spasm provocation tests. The questionnaire was sent to members of the Japanese Cine-angio Association in 81 cardiology hospitals in Japan. The completed surveys were returned from 20 hospitals, giving a response rate of 24.7%. Pharmacological spasm provocation tests increased in 2014 and vasospastic angina and variant angina also increased in 2014 compared with 2008, but the increase was not significant. Non-invasive spasm provocation tests such as hyperventilation tests and cold stress tests decreased remarkably in 2014. Spasm provocation tests were initially performed in the left coronary artery was employed in just 30% of the hospitals. The majority of institutions did not perform the spasm provocation testing in patients with unknown causes of heart failure or in survivors of ventricular fibrillation. Although 40% of the hospitals were not satisfied with standard spasm provocation tests, the majority of the hospitals agreed that spasm provocation tests will be necessary in the future. In general, the JCS guidelines contributed to the widespread use of provocative testing for coronary artery spasm in the real world. However, some issues about spasm still remained in the clinic.

Sueda S, Miyoshi T, Sasaki Y, Ohshima K, Sakaue T, Habara H, Kohno H. Complete definite positive spasm on acetylcholine spasm provocation tests: comparison of clinical positive spasm. Heart Vessels 2014; 31:143-51. [PMID: 25366988 DOI: 10.1007/s00380-014-0595-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2014] [Accepted: 10/17/2014] [Indexed: 02/07/2023]
Abstract
In the clinical grounds, patients with ≥90 % luminal narrowing during acetylcholine (ACh) testing had variable response. We investigated ischemic findings and chest symptoms in patients with ≥90 % luminal narrowing when performing ACh tests, retrospectively. We performed 763 ACh tests over 13 years (2001-2013). We analyzed chest symptoms and positive ischemic ECG changes during ACh tests. More than 90 % luminal narrowing was found in 441 patients (57.8 %) including 355 patients in the right coronary artery (RCA) and 363 patients in the left coronary artery (LCA). Chest symptom was observed in 386 patients (87.5 %) including 293 patients in the RCA and 304 patients in the LCA. ST elevation was found in 161 patients including 110 in the RCA and 85 patients in the LCA, while ST depression was recognized in 146 patients including 119 patients in the RCA and 117 patients in the LCA. Three quarter of patients with ≥90 % luminal narrowing had significant ischemic ECG changes, whereas two-third of patients with ≥90 % luminal narrowing complained usual chest pain accompanied with significant ischemic ECG changes. Unusual chest symptom was complained in 7.3 % patients with ≥90 % luminal narrowing. Neither chest symptom nor ECG changes were found in 30 patients (6.8 %) with ≥90 % luminal narrowing. A third of these patients had ischemic findings on non-invasive tests before catheterization and six patients had subtotal or total occlusion. We should realize some limitation to define positive coronary spasm based on the ischemic ECG change and chest symptom during ACh tests.
