[PMID: 37895453 PMCID: PMC10608489 DOI: 10.3390/life13102072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 10/14/2023] [Accepted: 10/14/2023] [Indexed: 10/29/2023] Open
Abstract
BACKGROUND The spasm provocation test (SPT) is a critical test for diagnosing vasospastic angina (VSA). However, the choice of vessel to be preferred for initiating the SPT-the right coronary artery (RCA) or the left coronary artery (LCA)-is unclear. This study aimed to assess SPT results including SPT-related complications while initiating the SPT in the RCA and LCA. METHODS We enrolled 225 patients who underwent coronary angiography and SPTs. The SPT was first performed in the RCA in 133 patients (RCA group) and the LCA in 92 patients (LCA group). We defined VSA as >90% narrowing of the coronary artery during the SPT, accompanied by chest pain and/or ST-T changes on the electrocardiogram. When coronary spasm occurs in two or more major coronary arteries, it is referred to as a multivessel spasm (MVS). SPT-related complications comprised atrial fibrillation, ventricular fibrillation, and unstable hemodynamics following catecholamine use. Analyses using propensity score matching (PSM) were performed in 120 patients. RESULTS No significant differences in the frequencies of VSA and complications were observed between the two groups (RCA: 79% and 19%, respectively; LCA: 85% and 22%, respectively). In both groups, spasms were most frequently provoked in the left anterior descending coronary artery (both p < 0.001) whereas spasms in the left circumflex coronary artery (LCX) were higher in the LCA group than in the RCA group (p = 0.015). Furthermore, no significant difference in the frequency of MVS was observed between both groups (RCA: 50%, LCA: 62%; p = 0.122). After PSM, no significant difference in the frequencies of VSA and complications were observed between the two groups (RCA: 82% and 15%, respectively; LCA: 88% and 18%, respectively). The frequencies of LCX spasms (RCA: 8%, LCA: 23%; p = 0.022) and MVS (RCA: 40%, LCA: 62%; p = 0.020) were higher in the LCA group than in the RCA group. CONCLUSIONS Although the diagnostic rate of VSA and frequency of SPT-related complications were similar in the two groups, the frequency of MVS was higher in the LCA group than in the RCA group because of the increase in the number of LCX spasms. A routine SPT may be started from the LCA.

Teragawa H, Oshita C, Uchimura Y. Clinical Characteristics and Prognosis of Patients with Vasospastic Angina Subjected to the Spasm Provocation Test and the Unavoidable Use of Nitroglycerin. J Cardiovasc Dev Dis 2023; 10:jcdd10010016. [PMID: 36661911 PMCID: PMC9863363 DOI: 10.3390/jcdd10010016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 12/21/2022] [Accepted: 12/30/2022] [Indexed: 01/03/2023] Open
Abstract
Background: Multi-vessel spasm (MVS) has a prognostic impact in patients with vasospastic angina (VSA). Thus, the presence of coronary spasm in both the left coronary artery (LCA) and right coronary artery (RCA) should be assessed through the spasm provocation test (SPT). Nitroglycerin (NTG) is used to avoid SPT-related complications; however, this unavoidable use of NTG may decrease the detection of MVS. Therefore, we investigated the frequency of the unavoidable use of NTG during SPT and clarified the clinical characteristics in patients with VSA who underwent the unavoidable use of NTG during STP. Methods: A total of 141 patients with positive SPT were evaluated. A positive SPT was defined as > 90% constriction in epicardial coronary arteries in response to acetylcholine, accompanied by the usual chest symptoms and/or ischaemic ST-T changes on electrocardiography. When a coronary spasm occurred, we usually wait for the spontaneous relief of the coronary spasm. However, if a prolonged coronary spasm or unstable haemodynamics occurred, 0.3 mg NTG was administered intracoronarily to promptly relieve the coronary spasm and this was defined as the unavoidable use of NTG. Even when the unavoidable use of NTG was administered in one coronary artery, an additional SPT was performed on another coronary artery. If a coronary spasm occurred in another coronary artery, a positive SPT was diagnosed. In contrast, if a coronary spasm was not induced after the unavoidable use of NTG, the judgement was classified as undiagnosed. The patients were divided into two groups according to the unavoidable use of NTG: U-NTG (n = 42) and the final use of NTG: F-NTG (n = 99). The clinical characteristics and frequencies of MVS (≥2 major coronary arteries in which a coronary spasm was provoked) and complications (malignant arrhythmia and unstable haemodynamics requiring catecholamines) during the SPT were compared between the groups. Results: Except for smoking status, all other clinical characteristics did not differ significantly between the groups. More current smokers were observed in the U-NTG group (29%) than in the F-NTG group (12%, p = 0.02). The frequency of MVS did not vary significantly between the groups (p = 0.28), with 64% for U-NTG and 55% for F-NTG. No significant difference was found between the groups in the frequency of severe complications during SPT (p = 0.83), with 2% for U-NTG and 3% for F-NTG. In the U-NTG group, the positive induction rate of coronary spasm in another coronary artery was 40% (17/42). Conclusions: The unavoidable use of NTG occurred in ~30% of patients with VSA, most of whom were current smokers. It did not decrease the detection of MVS and potentially prevented severe complications during SPT. Therefore, the unavoidable use of NTG is acceptable during SPT. However, an additional test may need to be performed to assess the presence of MVS.

Revisiting the use of the provocative acetylcholine test in patients with chest pain and nonobstructive coronary arteries: A five-year follow-up of the AChPOL registry, with special focus on patients with MINOCA. Transl Res 2021; 231:64-75. [PMID: 33232803 DOI: 10.1016/j.trsl.2020.11.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2020] [Revised: 10/25/2020] [Accepted: 11/17/2020] [Indexed: 12/31/2022]
Abstract
This study aimed to assess the angiographic characteristics, feasibility and safety of the provocative test with acetylcholine (AChT), and the influence on further treatment and prognosis of Middle European patients in 5-year follow-up, especially focusing on those with a history of myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA). The AChPOL Registry was an ongoing prospective single-center registry that included patients undergoing AChT from December 2010 to March 2013 for further diagnostic evaluation of a suspicious variant angina or coronary microvascular spasm, based on the COVADIS criteria. AChT was injected in incremental doses of 25, 50, and 75µg into the right coronary artery and 25, 50, and 100 µg into the left coronary artery, and the patients were followed up for 5 years. We enrolled 211 patients in the AChPOL Registry. Their mean age was 60.5 ± 7.8 years, with women accounting for 67.8%. The median follow-up was 56 months. AChT revealed variant angina in 99 patients (46.9%) and coronary microvascular spasm in the remaining 72 patients (34.1%). In patients with variant angina, spasm was most frequently observed in the left anterior descending artery (89.9%) and was most frequently diffuse (61.6%). In the microvascular spasm subgroup, there was a significantly higher rate of recurrent chest pain requiring hospitalization in the follow-up than in AChT negative patients. Interestingly, patients with a history of MINOCA had higher rates of MI and recurrent chest pain requiring hospitalization in the follow-up. We showed that AChT was safe in Middle European patients. In the follow-up patients with microvascular spasm and a history of MINOCA had the highest risk of MI and recurrent chest pain requiring hospitalization.

Abstract
Myocardial infarction (MI) with no obstructive coronary atherosclerosis (MINOCA) is a syndrome with different causes. Its prevalence ranges between 5 and 25% of all MIs. The prognosis is extremely variable, depending on the causes of MINOCA. Clinical history, echocardiography, coronary angiography, and left ventriculography represent the first-level diagnostic investigations. Nevertheless, additional tests are required in order to establish its specific cause, thus allowing an appropriate risk stratification and treatment. We review pathogenesis, diagnosis, prognosis, and therapy of MINOCA and propose an algorithm for its management.

Abstract
We examined the safety of acetylcholine (ACh) and ergonovine (ER) tests retrospectively and investigated the optimal protocol of provocation test for diagnosis of multivessel coronary spasm. We performed 1546 ACh tests and 1114 ER tests during 23 years. ACh was injected in incremental doses of 20/50/80 μg into the right coronary artery (RCA) and of 20/50/100/200 μg into the left coronary artery (LCA) over 20 s. ER was administered in total doses of 40 μg into the RCA and of 64 μg into the LCA over 2-4 min. When a coronary spasm was induced and did not resolve spontaneously within 3 min after the completion of ACh/ER injection, or when hemodynamic instability due to coronary spasms occurred, 2.5-5.0 mg of nitrate was administered into the responsible vessel. To relive provoked spasm, it is necessary to administer nitrate in 31 cases by ACh and in 76 cases by ER (2.0 vs. 6.8 %, p < 0.01) before another vessel attempts. Multivessel spasms were often observed in LCA testing than in RCA testing on both agents [ACh: 78.6 % (11/14) vs. 11.8 % (2/17), p < 0.001, ER: 37.8 % (14/37) vs. 20.5 % (8/39), ns]. Even after the administration of nitrates, positive coronary spasm was obtained in 21.1 % by ACh and 52.9 % by ER tests on another coronary artery. No irreversible complications were recognized on both tests. We should firstly perform spasm provocation tests in the LCA and we may be able to diagnose another vessel spasm by performing the complete spasm provocation tests after the administration of nitrates to relieve provoked spasm in the first attempt.

Abstract
OBJECTIVES This study evaluated the safety of coronary reactivity testing (CRT) in symptomatic women with evidence of myocardial ischemia and no obstructive coronary artery disease (CAD). BACKGROUND Microvascular coronary dysfunction (MCD) in women with no obstructive CAD portends an adverse prognosis of a 2.5% annual major adverse cardiovascular event (MACE) rate. The diagnosis of MCD is established by invasive CRT, yet the risk of CRT is unknown. METHODS The authors evaluated 293 symptomatic women with ischemia and no obstructive CAD, who underwent CRT at 3 experienced centers. Microvascular function was assessed using a Doppler wire and injections of adenosine, acetylcholine, and nitroglycerin into the left coronary artery. CRT-related serious adverse events (SAEs), adverse events (AEs), and follow-up MACE (death, nonfatal myocardial infarction [MI], nonfatal stroke, or hospitalization for heart failure) were recorded. RESULTS CRT-SAEs occurred in 2 women (0.7%) during the procedure: 1 had coronary artery dissection, and 1 developed MI associated with coronary spasm. CRT-AEs occurred in 2 women (0.7%) and included 1 transient air microembolism and 1 deep venous thrombosis. There was no CRT-related mortality. In the mean follow-up period of 5.4 years, the MACE rate was 8.2%, including 5 deaths (1.7%), 8 nonfatal MIs (2.7%), 8 nonfatal strokes (2.7%), and 11 hospitalizations for heart failure (3.8%). CONCLUSIONS In women undergoing CRT for suspected MCD, contemporary testing carries a relatively low risk compared with the MACE rate in these women. These results support the use of CRT by experienced operators for establishing definitive diagnosis and assessing prognosis in this at-risk population.
