Abstract
Prinzmetal's angina typically features spasms of the coronary arteries due to the hyperreactivity of the vascular smooth muscle cells of the vessels to a nonspecific stimulus. Reports of coronary spasm during general anesthesia are rare, but in such cases, diagnosis is suggested by a framework of angina at rest and changes in the electrocardiogram (ECG) or coronary reactivity tests with ergonovine or acetylcholine. The present study describes a case of coronary spasm induced by general anesthesia associated with several cardiovascular risk factors and the usage of vasoactive drugs that was documented by angiography without using stimulating drugs and treated with intracoronary nitroglycerin. The patient was a 58-year-old male who was designated for carotid endarterectomy due to the stenosis (70%) of the right internal carotid artery by an atheromatous plaque after visiting the emergency department with a sensorimotor deficit in the left upper limb and bifrontal headaches with sudden onset. During the surgical intervention, after the administration of 10 mg of intravenous ephedrine, cardiorespiratory arrest occurred, with alternation between defibrillable and non-defibrillable heart paces. After the recovery of spontaneous circulation after 50 minutes of resuscitation maneuvers, the patient was transported to the hemodynamics laboratory, where there were recurrent episodes of ventricular fibrillation during the angioplasty of the anterior descending artery. After direct stent implantation, pre- and post-stent spasms were verified and reversed after the administration of intracardiac nitroglycerin. The spasm was a possible complication of anesthesia and responded to treatment with nitrates and calcium channel blockers. We would like to emphasize the importance of cardiac monitoring during surgery and anesthesia.

Abstract
Calcium channel blockers (CCBs) are the first-line treatment for coronary artery spasm (CAS). When CAS-related angina symptoms are not well controlled by CCB therapy, long-acting nitrates or (where available) nicorandil can be added as second-line medications. In the case of CAS refractory to standard treatments, several other alternative drugs and interventions have been proposed, including the Rho-kinase inhibitor fasudil, anti-adrenergic drugs, neural therapies and percutaneous coronary interventions. In patients with syncope or cardiac arrest caused by CAS-related tachyarrhythmias, or even bradyarrhythmias, implantation of an ICD or pacemaker, respectively, should be considered according to the risk of recurrence and efficacy of vasodilator therapy.

Identification of cell-biologic mechanisms of coronary artery spasm and its ex vivo diagnosis using peripheral blood-derived iPSCs. Biomater Res 2023; 27:16. [PMID: 36803875 PMCID: PMC9938986 DOI: 10.1186/s40824-023-00345-2] [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: 07/05/2022] [Accepted: 01/25/2023] [Indexed: 02/20/2023] Open
Abstract
BACKGROUND Although vasospastic angina (VSA) is known to be caused by coronary artery spasm, no study has fully elucidated the exact underlying mechanism. Moreover, in order to confirm VSA, patients should undergo invasive coronary angiography with spasm provocation test. Herein, we investigated the pathophysiology of VSA using peripheral blood-derived induced pluripotent stem cells (iPSCs) and developed an ex vivo diagnostic method for VSA. METHODS AND RESULTS With 10 mL of peripheral blood from patients with VSA, we generated iPSCs and differentiated these iPSCs into target cells. As compared with vascular smooth muscle cells (VSMCs) differentiated from iPSCs of normal subjects with negative provocation test, VSA patient-specific iPSCs-derived VSMCs showed very strong contraction in response to stimulants. Moreover, VSA patient-specific VSMCs exhibited a significant increase in stimulation-induced intracellular calcium efflux (Changes in the relative fluorescence unit [ΔF/F]; Control group vs. VSA group, 2.89 ± 0.34 vs. 10.32 ± 0.51, p < 0.01), and exclusively induced a secondary or tertiary peak of calcium efflux, suggesting that those findings could be diagnostic cut-off values for VSA. The observed hyperreactivity of VSA patient-specific VSMCs were caused by the upregulation of sarco/endoplasmic reticulum Ca2+-ATPase 2a (SERCA2a) due to its enhanced small ubiquitin-related modifier (SUMO)ylation. This increased activity of SERCA2a was reversed by treatment with ginkgolic acid, an inhibitor of SUMOylated E1 molecules (pi/µg protein; VSA group vs. VSA + ginkgolic acid, 52.36 ± 0.71 vs. 31.93 ± 1.13, p < 0.01). CONCLUSIONS Our findings showed that abnormal calcium handling in sarco/endoplasmic reticulum could be induced by the enhanced SERCA2a activity in patients with VSA, leading to spasm. Such novel mechanisms of coronary artery spasm could be useful for drug development and diagnosis of VSA.

Abstract
Coronary artery spasm (CAS) is a reversible phenomenon caused by spontaneous excessive vascular smooth muscle contractility and vascular wall hypertonicity, which results in partial or complete closure of the lumen of normal or atherosclerotic coronary arteries. The clinical picture of CAS includes chest discomfort which is similar in quality to that of stable effort angina. Mechanisms underlying the development of CAS are still unclear. CAS certainly is a multifactorial disease. In this review, we paid attention to the role of the main pathophysiologic mechanisms in CAS: endothelial dysfunction, chronic inflammation, oxidative stress, smooth muscle hypercontractility, atherosclerosis and thrombosis, and mutations leading to deficient aldehyde dehydrogenase 2 (ALDH2) activity. These findings might shed novel insight on the underlying mechanisms and identify potential diagnostic and therapeutic targets for cardiovascular diseases in the future.

Abstract
Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a heterogeneous group of conditions that include both atherosclerotic (coronary plaque disruption) and non-atherosclerotic (spontaneous coronary artery dissection, coronary artery spasm, coronary artery embolism, coronary microvascular dysfunction, and supply–demand mismatch) causes resulting in myocardial damage that is not due to obstructive coronary artery disease. Failure to identify the underlying cause may result in inadequate and inappropriate therapy in these patients. The cornerstone of managing MINOCA patients is to identify the underlying mechanism to achieve the target treatment. Intravascular imaging is able to identify different morphologic features of coronary plaques, while cardiac magnetic resonance is the gold standard for detection of myocardial infarction in the setting of MINOCA. In this review, we summarize the relevant clinical issues, contemporary diagnosis, and treatment options of MINOCA.

Abstract
Vasospastic angina (VSA) is an under-appreciated cause of chest pain. It is characterised by transient vasoconstriction of the coronary arteries and plays a significant role in the pathogenesis of stable angina and acute coronary syndromes. Complex mechanistic pathways characterised by endothelial dysfunction and smooth muscle hypercontractility lead to a broad spectrum of clinical manifestations ranging from recurrent angina to fatal arrhythmias. Invasive provocation testing using intracoronary acetylcholine or ergonovine is considered the current gold standard for diagnosis, but there is a wide variation in protocols amongst different institutions. Conventional pharmacological therapy relies on calcium channel blockers and nitrates; however, refractory VSA has limited options. This review evaluates the pathophysiology, diagnostic challenges, and management strategies for VSA. We believe global efforts to standardise diagnostic and therapeutic guidelines will improve the outcomes for affected patients.

Abstract
The underlying mechanisms of coronary spastic angina (CSA) is not well understood. It is unclear if an infection can trigger coronary vasospasm; the co-occurrence of sepsis and CSA has rarely been reported. We describe the case of a 47-year-old man who suddenly developed a complete atrioventricular block and an episode of cardiac arrest while undergoing treatment for sepsis secondary to invasive group A streptococci. Emergency coronary angiography and provocation revealed spasm of the right coronary artery, which had led to the atrioventricular block. The spasm was relieved following administration of calcium-channel blockade, and no subsequent recurrence was documented. Due to several underlying mechanisms, sepsis may be a potential risk factor of coronary spasm and episodes of this condition have been missed or misdiagnosed. Physicians should be aware of CSA as a potential complication during treatment of sepsis.

Abstract
Patients with angina pectoris, the cardinal symptom of myocardial ischaemia, yet without significant flow-limiting epicardial artery stenosis represent a diagnostic and therapeutic challenge. Coronary artery spasm (CAS) is an established cause for anginal chest pain in patients with angiographically unobstructed coronary arteries. CAS may occur at the epicardial level and/or in the microvasculature. Although the underlying pathophysiological mechanisms of CAS are still largely unclear, endothelial dysfunction and vascular smooth muscle cell (VSMC) hyperreactivity seem to be involved as major players, although their contribution to induce CAS is still seen as controversial. This article will look at the role and possible mechanistic interplay between an impaired endothelial and VSMC function in the pathogenesis of CAS.

Abstract
In 2006, Takotsubo syndrome (TTC) was described as a distinct type of stress-induced cardiomyopathy (stress cardiomyopathy). However, when thinking about Takotsubo cardiomyopathy from the viewpoints of the AHA and ESC classifications, 2 possible problems may arise. The first potential problem is that a forecast of disease outcome is lacking in the ESC classification, whereas the AHA only states that 'outcome is favorable with appropriate medical therapy'. However, based on the literature data, one can make a general conclusion that occurrence of myocardial lesions in TTC (i.e., myocardial fibrosis and contraction-band necrosis) causes the same effects as in other diseases with similar levels of myocardial damage and should not be considered to have a lesser impact on mortality. To summarise, TTC can cause not only severe complications such as pulmonary oedema, cardiogenic shock, and dangerous ventricular arrhythmias, but also damage to the myocardium, which can result in the development of potentially fatal conditions even after the disappearance of LV apical ballooning. The second potential problem arises from the definition of TTC as a stress cardiomyopathy in the AHA classification. In fact, the main factors leading to TTC are stress and microvascular anginas, since, as has been already discussed, coronary spasm can cause myocardium stunning, resulting in persistent apical ballooning. Thus, based on this review, 3 distinct types of stress cardiomyopathies exist (variant angina, microvascular angina, and TTC), with poor prognosis. Adding these diseases to the classification of cardiomyopathies will facilitate diagnosis and preventive prolonged treatment, which should include intensive anti-stress therapy.

Abstract
Myocardial ischaemia results from a direct mismatch between oxygen supply and demand, commonly arising as a result of coronary atherosclerosis, microvascular dysfunction or acute thrombosis and luminal obstruction. However, transient ischaemia may also occur due to coronary spasm leading to acute and unexpected myocardial ischaemia without obvious visible coronary pathology. Aside from symptoms of chest pain, coronary spasm can cause infarction, LV impairment, promote life threatening arrhythmias and ultimately sudden cardiac death. While therapeutic options are available, controversies exist around diagnosis, pathology, management and prognosis. This review summarises some of the common questions in this area. In particular we explore and discuss the available evidence for the pharmacological treatment of coronary spasm, and strategies for identification and management of very high risk patients to try and reduce the incidence of sudden premature death. Myocardial ischaemia results from a mismatch between oxygen supply and demand. Spasm might lead to myocardial ischaemia without visible coronary pathology. Coronary spasm can cause infarction, LV impairment and sudden cardiac death.

Abstract
Background We previously showed that phospholipase C (PLC)-δ1 activity was enhanced by 3-fold in patients with coronary spastic angina (CSA). We also reported that p122Rho GTPase-activating protein/deleted in liver cancer-1 (p122RhoGAP/DLC-1) protein, which was discovered as a PLC-δ1 stimulator, was upregulated in CSA patients. We tested the hypothesis that p122RhoGAP/DLC-1 overexpression causes coronary spasm. Methods and Results We generated transgenic (TG) mice with vascular smooth muscle (VSM)-specific overexpression of p122RhoGAP/DLC-1. The gene and protein expressions of p122RhoGAP/DLC-1 were markedly increased in the aorta of homozygous TG mice. Stronger staining with anti-p122RhoGAP/DLC-1 in the coronary artery was found in TG than in WT mice. PLC activities in the plasma membrane fraction and the whole cell were enhanced by 1.43 and 2.38 times, respectively, in cultured aortic vascular smooth muscle cells from homozygous TG compared with those from WT mice. Immediately after ergometrine injection, ST-segment elevation was observed in 1 of 7 WT (14%), 6 of 7 heterozygous TG (84%), and 7 of 7 homozygous TG mice (100%) (p<0.05, WT versus TGs). In the isolated Langendorff hearts, coronary perfusion pressure was increased after ergometrine in TG, but not in WT mice, despite of the similar response to prostaglandin F2α between TG and WT mice (n = 5). Focal narrowing of the coronary artery after ergometrine was documented only in TG mice. Conclusions VSM-specific overexpression of p122RhoGAP/DLC-1 enhanced coronary vasomotility after ergometrine injection in mice, which is relevant to human CSA.

Abstract
Coronary artery spasm after coronary artery bypass surgery may result in life-threatening arrhythmias, circulatory collapse, or death. We report two cases of coronary artery spasm after coronary artery bypass surgery, one of which developed ventricular fibrillation requiring extracorporeal membrane oxygenation support. Both patients were discharged in good condition and are currently followed as outpatients. Unexpected sudden hemodynamic compromise could be due to coronary vasospasm, and this should be considered as one of the possible differential diagnoses. We were able to prevent the lethal consequences seen with coronary artery spasm by early diagnosis and management.

Abstract
Coronary spasm is an important and often overlooked etiology of chest pain. Although coronary spasm, or Prinzmetal's angina, has been thought of as benign, contemporary studies have shown serious associated adverse outcomes, including acute coronary syndrome, arrhythmia, and death. Definitive diagnosis of coronary spasm can at times be difficult, given the transience of symptoms. Numerous agents have been historically described for provocative testing. We provide a review of published data for the role of provocation testing in the diagnosis of coronary spasm.

Abstract
Atherothrombosis has long been recognized as an important mechanism of cardiac events in ischemic heart disease, and large multicenter clinical studies have shown the benefit of antiplatelet agents, statins, beta-blockers and angiotensin converting enzyme inhibitors in preventing these events. However, more recent studies have been less successful at showing incremental gains in targeting these mechanisms, suggesting that the limits of this strategy have been exploited. Coronary vasoconstriction is another important mechanism in ischemic heart disease but has received little attention and yet is a potential therapeutic target. In the current review, the reasons why coronary vasconstriction has received insufficient consideration are explored. In particular, we need to change our approach from lumping heterogeneous clinical entities together to focusing on clinically-discrete homogeneous groups with a common mechanism and thus therapeutic target. The role of coronary vasoconstriction is examined in the various ischemic syndromes (variant angina, chronic stable angina, acute coronary syndromes and syndrome X) and the underlying mechanisms discussed. Finally, in order to advance studies in this field, an innovative research strategy is proposed, including: (1) selection of paradigmatic cases for the various ischemic syndromes; (2) candidate therapeutic targets; and (3) approaches in assessing the clinical efficacy of these potential therapies.

Abstract
Coronary artery vasospasm rarely appears as a diffuse phenomenon that involves all the coronary tree. We present a clinical case of acute myocardial infarction complicated by ventricular fibrillation and cardiogenic shock. Urgent coronary angiography showed occlusion of proximal Circumflex coronary artery and a TIMI I flow in the left anterior descending artery due to severe, diffuse coronary vasospasm. Patient was successfully treated with intra-aortic balloon pump and intracoronary bolus of nitroglycerin with restoration of flow in left coronary branches and complete resolution of shock.

Abstract
Coronary (artery) spasm plays an important role in the pathogenesis of ischemic heart disease, including stable angina, unstable angina, myocardial infarction, and sudden death. The prevalence of coronary spasm differs among populations, is higher in Japan and Korea than in the Western countries probably due to genetic as well as environmental factors. Coronary spasm occurs most often from midnight to early morning and is usually not induced by exercise in the daytime. The attacks of coronary spasm are associated with either ST segment elevation or depression, or negative U wave on ECG. Patients with multi-vessel coronary spasm may suffer from lethal arrhythmia, including advanced AV block, ventricular tachycardia or fibrillation, or even sudden death, and they are often resistant to conventional medical therapy including Ca-channel blockers (CCBs). Endothelial nitric oxide (NO) activity is reduced and markers of oxidative stress are elevated in patients with coronary spasm. Thrombogenesis is enhanced and plasma levels of hsCRP and P-selection are elevated in patients with coronary spasm. Thus, patients with coronary spasm have endothelial dysfunction and are suffering from a low-grade chronic inflammation. Polymorphisms of endothelial NO synthase, smoking, and low-grade inflammation are the most important risk factors for coronary spasm. Coronary spasm is a hyper-contraction of coronary smooth muscle triggered by an increase of intracellular Ca2+ in the presence of an increased Ca2+ sensitivity. It has been shown that RhoA/ROCK pathway is involved in Ca2+ sensitivity and that the reduced endothelial NO activity results in increased Ca2+ sensitivity through enhanced RhoA/ROCK pathway. Accordingly, it is possible that in addition to CCBs, RhoA/ROCK pathway blockers may prove to be useful for the treatment of coronary spasm.

Abstract
BACKGROUND There is an intimate relationship between activation of the sympathetic nervous system and myocardial ischemia. This study examined whether plasma levels of dopamine, a precursor of norepinephrine, may provide prognostic information in coronary artery disease (CAD). METHODS AND RESULTS Plasma levels of free dopamine were measured by high-performance liquid chromatography in 210 consecutive patients with stable CAD. The patients were prospectively followed up for a period of < or =36 months until occurrence of a clinical coronary event. Coronary events occurred in 37 patients during follow-up. In Kaplan-Meier survival analysis, higher dopamine levels (> or =30 pg/ml) resulted in a higher event probability (p<0.01). Multivariate Cox hazards analysis showed that higher dopamine levels were a significant and independent risk factor for future coronary events (hazard ratio 3.3, 95% confidence interval 1.3-8.1, p<0.01). Furthermore, patients with higher dopamine levels had lower left ventricular (LV) ejection fraction and higher levels of brain natriuretic peptide, C-reactive protein, and fibrinogen than those with lower dopamine levels. CONCLUSIONS Plasma levels of free dopamine are increased in association with a decrease in LV function and an increase in inflammatory risk markers. Higher free dopamine levels are an independent risk factor for future coronary events in CAD patients.

Abstract
Spontaneous coronary artery spasm is an important cause of morbidity both in patients with coronary artery disease and in those with variant angina. A number of pharmacological agents have been identified which can provoke coronary artery spasm in susceptible patients. The role of provocation testing in the clinical diagnosis of coronary spasm is controversial. This is reflected by variations in the clinical use of provocation testing between specialist cardiac centres. Provocation testing appears to be a sensitive method of identifying patients with variant angina and active disease but such patients can often be diagnosed clinically. The specificity is less clear. There is little evidence that altering patient therapy on the basis of a positive test modifies prognosis. There may be a role for provocation testing in rare patients with refractory disease to identify a target site for coronary stenting. A more widespread use of these tests in patients with undiagnosed chest pain syndromes would not currently be recommended.

Abstract
Coronary spasm plays an important role in the pathogenesis of not only variant angina but also coronary heart disease in general including acute coronary syndromes, especially in the Japanese population. The vascular endothelium has been reported to be a multifunctional organ whose integrity is essential for normal vascular physiology. Vascular endothelial dysfunction can be a critical factor in the pathogenesis of ischemic heart disease. Acetylcholine and methacholine cause vasodilation by endothelium-derived relaxing factor when the endothelium is functioning normally, whereas they cause vasoconstriction when the endothelium is removed or damaged. Coronary spasm can be induced by a variety of stimuli with different mechanisms of action, including acetylcholine and methacholine. Patients with coronary spasm may have a disturbance in endothelial function as well as local hyperreactivity of the coronary arteries.

Abstract
We report a case of anaphylactic reaction occurring during general anesthesia that may have been accompanied by a coronary artery spasm. The present case and a review of the medical literature suggest that coronary artery spasm is evoked by common vasoactive mediators with anaphylactic reactions. Coronary artery spasm should be counted as a symptom of the cardiovascular manifestation of anaphylaxis. Clinicians should be aware of this possible complication when treating an anaphylactic reaction, especially in patients at risk for atherosclerosis. Early recognition of ST segment elevation is essential for diagnosis and treatment of coronary artery spasm.

Abstract
The incidence of provoked coronary spasm with the standard single spasm provocation test has been relatively low in patients with rest angina. The present study examined the clinical usefulness of a newly designed spasm provocation test, an intracoronary injection of acetylcholine (ACh) following an ergonovine (ER) test, in patients with rest angina who demonstrated low disease activity and atypical chest pain. Triple sequential spasm provocation tests were performed in 24 patients with atypical chest pain who had no ischemia and in 40 patients with rest angina who had distinct ischemia. Initially, an ACh test (20-100 microg) and then an ER test (40-64 microg) were performed and then, if no spasm was provoked, an intracoronary injection of ACh was given after the ER test to evaluate coronary spasm. Coronary spasm was defined as total or subtotal occlusion. In the 24 patients with atypical chest pain, no spasm was provoked by intracoronary injection of either ACh or ER, but coronary spasms were induced in 2 patients using the new method, with the remaining 22 not experiencing spasm (specificity of new method, 92%). In the 40 patients with rest angina, intracoronary injection of ACh induced coronary spasm in 22 patients (group I) and 6 (group II) demonstrated spasm with intracoronary injection of ER. Coronary spasm was not induced by either the ACh test or the ER test in 12 patients (group III). The intracoronary administration of ACh after the ER test provoked spasm in 11 of 12 patients. Diffuse spasms were provoked in 10 of 11 patients. In patients with rest angina, the frequency of chest pain attacks in 1 month experienced by patients in group III (0.8+/-0.8) was significantly lower than that of patients in group I (7.0+/-5.3, p<0.01) or II (3.5+/-2.3, p<0.05). No serious or irreversible complications related to this new combined method were observed. In conclusion, this method was safe and reliable for the induction of coronary spasm in patients with rest angina who may have low disease activity.

Abstract
Attacks of variant angina usually respond promptly to sublingual administration of short-acting nitrates (nitroglycerin, 0.3 to 0.4 mg, or isosorbide dinitrate, 5 to 10 mg), which may be repeated after 3 to 5 minutes if pain persists. In the rare cases resistant to sublingual nitrates, sublingual nifedipine (5 to 10 mg) or, when readily available, intravenous nitrates (nitroglycerin or isosorbide dinitrate, 2 to 10 mg) or calcium antagonists (verapamil, 5 to 10 mg, or diltiazem, 0.15 mg/kg) can be given. All attempts to prevent ischemic attacks by means of specific receptor blockade in patients with vasospastic angina have been unsatisfactory. This may be either because the doses of the blockers used were insufficient or, more likely, because the blockade of a single receptor-agonist interaction leaves receptors for other vasoconstrictor stimuli unopposed and therefore capable of eliciting spasm. Thus, for instance, alpha-adrenergic, serotoninergic, and thromboxane A(2) antagonists all failed to reduce significantly the number of anginal attacks, although they appeared to be effective in some patients. Until the actual causes of the coronary smooth muscle hyperreactivity to constrictor stimuli are known, treatment of vasospastic angina is based on the use of nonspecific vasodilators. Indeed, the mainstay of pharmacologic treatment of coronary artery spasm is calcium channel blocking agents together with nitrates to cover the periods in which spasm is most likely to occur. These powerful vasodilating agents, at their usual doses, are able immediately and completely to control the recurrences of ischemic attacks in as many as 80% of patients. Moreover, some studies have shown that use of calcium antagonists significantly improves clinical outcome in patients with variant angina.

Abstract
Dobutamine stress echocardiography (DSE) has been widely used for the noninvasive diagnosis of obstructive coronary artery disease. The ST-segment elevation during DSE has been reported as an infrequent event, caused by old myocardial infarction and/or critical coronary narrowings. The patient presented here was a 35-year-old man with a recent history of nonexertional chest pain. He had hypercholesterolemia and a history of heavy smoking as risk factors. The patient developed ST-segment elevation with chest pain during 40 mcg/min dobutamine infusion for the stress echocardiographic examination. Subsequent coronary angiograms revealed only mild coronary atherosclerosis. It is speculated that coronary spasm occurred in this patient as a paradoxical response to increased coronary blood flow with dobutamine administration.

Abstract
The aim of this study was to determine whether isolated coronary arteries from patients with variant angina show hyperreactivity and/or supersensitivity to acetylcholine in vitro. Coronary arterial rings were obtained at autopsy within 3 h after death from six coronary arteries having spasm in four patients with variant angina and from 22 coronary arteries in 14 control patients with non-cardiac death. The coronary rings were suspended in the organ chamber filled with Krebs Henseleit solution bubbled with 95% O2 + 5% CO2, and their isometric tensions were monitored. Arterial rings isolated from both the patients with variant angina and the controls contracted dose-dependently in response to acetylcholine (10(-9)-10(-5) mol/l). EC50 of acetylcholine (i.e. concentration producing 50% of maximum contraction) was not significantly different between the coronary arteries from patients with variant angina and those from controls, but maximum contraction elicited by acetylcholine (expressed as a percentage of the contraction elicited by 60 mmol/l KCl) was significantly greater in the coronary arteries from patients with variant angina than those from controls. In conclusion, the isolated coronary arteries from patients with variant angina have hypercontractile reactivity to acetylcholine. This intrinsic alteration of the coronary reactivity to acetylcholine may play a role in the genesis of coronary spasm occurring in the situations of enhanced parasympathetic nervous discharge.

Abstract
Intravenous inotropic agents promote increased myocardial contractility via elevation of myocyte calcium concentrations, a mechanism that is also known to promote the development of cardiac arrhythmias. The purpose of this article is to review the electrophysiologic effects and relative potential for proarrhythmia associated with dobutamine, dopamine, and the phosphodiesterase inhibitors amrinone and milrinone. Dobutamine increases sinoatrial node automaticity and decreases atrial and atrioventricular (AV) node refractoriness and AV nodal conduction time. The drug also decreases ventricular refractoriness in both healthy and ischemic myocardium. Dobutamine has been shown to increase heart rate in a dose-related fashion in animals and in humans. In humans, dobutamine has been reported to induce ventricular ectopic activity (VEA) in 3% to 15% of patients, although VEAs are often asymptomatic, requiring no intervention. Ventricular tachycardia (VT) associated with dobutamine appears to occur rarely. Patients with underlying arrhythmias or heart failure or those receiving excessive doses of dobutamine are at greatest risk for proarrhythmia. Dopamine increases automaticity in Purkinje fibers and has a biphasic effect on action potential duration. Dopamine has been reported to induce atrial or ventricular arrhythmias in animals. In humans, dopamine may be associated with dose-related sinus tachycardia but has also been reported to cause VEA, which is usually asymptomatic. Dopamine-associated VT appears to occur rarely. Dopamine produces greater elevations in heart rate or frequency of ventricular premature beats at a given value of cardiac index than does dobutamine. The phosphodiesterase inhibitors amrinone and milrinone increase conduction through the AV node and decrease atrial refractoriness. Intravenous administration of these drugs may result in sinus tachycardia in some patients and has been reported to cause VEA, which is often asymptomatic, in up to 17% of patients. VT has also been reported in association with short-term use of intravenous phosphodiesterase inhibitors. In summary, intravenous inotropic agents may be associated with proarrhythmic effects in some patients. The primary arrhythmias reported are sinus tachycardia and VEA, although other supraventricular or ventricular arrhythmias have been reported less commonly. However, clinically significant proarrhythmic effects associated with these agents appear to occur rarely, and, at conventional doses, intravenous inotropic agents are relatively safe with respect to proarrhythmic effects.

Abstract
OBJECTIVE To review the electrophysiologic properties and the in vitro, ex vivo, animal, and human data regarding proarrhythmic effects of intravenous vasopressors. DATA SOURCES A comprehensive (MEDLINE) search (1960-1994) was conducted for dopamine, epinephrine, norepinephrine, phenylephrine, and methoxamine. STUDY SELECTION In vitro and ex vivo studies and investigations performed in animals or humans reporting electrophysiologic and/or proarrhythmic effects of the above intravenous vasopressors were selected. A comprehensive search of all human studies involving these agents was conducted to reveal any proarrhythmic effects that may have been reported. In addition, case reports of proarrhythmic effects associated with these agents were reviewed. DATA EXTRACTION Data regarding electrophysiologic and proarrhythmic effects of these agents were extracted from in vitro, ex vivo, animal, and human studies. Because few studies with the specific purpose of investigating proarrhythmic effects of vasopressors have been performed in humans, all studies involving these drugs for evaluation of hemodynamic effects, clinical efficacy, or other endpoints in humans were reviewed. In addition, data were extracted from case reports of proarrhythmic effects associated with these agents. DATA SYNTHESIS Dopamine increases automaticity in Purkinje fibers and has a biphasic effect on action-potential duration. Dopamine has caused both atrial and ventricular tachyarrhythmias in animals. Human data have revealed dose-related sinus tachycardia, with few reports of clinically significant ventricular arrhythmias. Epinephrine shortens sinus cycle length, increases atrial and ventricular automaticity, promotes atrioventricular nodal conduction, and decreases ventricular effective refractory period (ERP). It is well known to induce ventricular fibrillation and decrease the ventricular fibrillation threshold (VFT) in ex vivo models as well as intact animals. In humans, epinephrine may cause dose-related sinus tachycardia, supraventricular arrhythmias, or, more commonly, ventricular arrhythmias. Norepinephrine increases automaticity of the sinoatrial node, atria, and ventricles; promotes atrioventricular nodal conduction; and decreases ventricular ERP. In vitro/ex vivo and animal data have shown that norepinephrine significantly decreases VFT. Although electrophysiologic studies suggest that norepinephrine may be proarrhythmic, few supporting data exist in humans. Phenylephrine demonstrates differential electrophysiologic effects in atrial and ventricular tissue. Most data suggest that phenylephrine causes prolongation of the ventricular ERP. Rather than being proarrhythmic, phenylephrine may be protective against arrhythmias. The drug elevates VFT in dogs. In humans, phenylephrine effectively terminates supraventricular tachycardias and may be protective against ventricular arrhythmias. Like phenylephrine, methoxamine elevates the repetitive extrasystolic, atrial, and ventricular fibrillatory thresholds. Methoxamine also may have antiarrhythmic effects because of alpha-receptor stimulation and reflex vagal activity. Despite the relatively low risk of arrhythmogenicity associated with intravenous vasopressors, patients should be monitored for potential proarrhythmic effects and appropriate action taken as necessary. Critically ill patients often have concurrent conditions, electrolyte disturbances, and underlying arrhythmias that predispose them to a higher risk of vasopressor proarrhythmic effects. CONCLUSIONS Controlled data supporting the proarrhythmic potential of intravenous vasopressors in humans are lacking. Sinus tachycardia, asymptomatic ventricular ectopic activity, and other ventricular or supraventricular arrhythmias have been reported in association with dopamine and epinephrine. Phenylephrine and methoxamine have been associated with sinus bradycardia, but otherwise may be antiarrhythmic. Intravenous vasopressors appear relatively safe w

Abstract
To investigate the mechanism of coronary spasm, we compared the action of acetylcholine with that of ergonovine in 11 patients with vasospastic angina (group 1) and in 15 patients with chest pain (group 2). Coronary arteriography was performed immediately after the patients received intracoronary injections of titrated increments of each agent. In the patients in group 1 occlusive or near-occlusive (99% luminal narrowing) coronary spasm associated with angina and ischemic electrocardiographic ST changes was noted in nine of 11 patients receiving acetylcholine and in all 11 patients receiving ergonovine. The region and the degree of the most severe coronary spasm on coronary arteriograms evoked by the two agents were the same in nine of the 11 patients in group 1. In the other two patients in group 1, spontaneous focal coronary spastic stenosis in the baseline coronary arteriogram was relieved by the intracoronary injection of acetylcholine, and a focal coronary occlusive spasm in the same region was induced repeatedly by the subsequent intracoronary injection of ergonovine (paradoxic phenomenon). In contrast, occlusive or near-occlusive coronary spasm was not induced by either agent in any patient in group 2. These results suggest that the two provocative tests for coronary spasm that involve acetylcholine and ergonovine are clinically useful in the diagnosis of vasospastic angina, but testing with intracoronary ergonovine is needed when a spontaneous focal coronary spasm is relieved by the intracoronary injection of acetylcholine. The results also indicate that in many patients with vasospastic angina, nonspecific hypersensitivity to acetylcholine or ergonovine in a definite region of the coronary arteries generally plays an important role in the induction of coronary spasm.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To evaluate the thrombolytic effects of the native tissue-type plasminogen activator (t-PA), the authors used a thrombus model simulating clinical situations. The native t-PA (AK-124) was obtained from human-derived normal cells. Experimental canine coronary thrombosis was produced by partial constriction and endothelial denudation of the vessel. In 19 dogs, coronary occlusive thrombus was produced. Three hours after total occlusion of the coronary artery with thrombus, the authors attempted the thrombolytic therapy in 16 dogs. Histologically, three-hour thrombus was composed of a mixture of platelet aggregates, fibrin, and blood cells. They infused 0.375 mg/kg t-PA intravenously in 7 dogs and 20,000 IU/kg urokinase (UK) in 9. Coronary recanalization was achieved in 5 (71%) with t-PA infusion and 6 (67%) with UK infusion. Plasma fibrinogen levels decreased to 76% of preinfusion value in the dogs with t-PA infusion and to 34% in those with UK infusion. Coronary reocclusion occurred in 2 dogs with t-PA and 3 with UK. Thus, the native t-PA (AK-124) can provide coronary thrombolysis without severe depletion of plasma fibrinogen levels.

Abstract
Coronary artery spasm during the early postoperative period following cardiopulmonary bypass for coronary artery surgery can be an unrecognized cause of sudden, severe cardiopulmonary collapse. The literature regarding perioperative coronary artery spasm is reviewed, and methods of prevention, diagnosis, and treatment are suggested. Preoperative angina at rest appears to be an important identifying factor in patients who experience postoperative coronary spasm. Anatomically, the presence of a relatively normal, dominant right coronary may also indicate increased risk for early post-coronary bypass spasm. Acute hypotension is often the first sign of coronary artery spasm, and conventional treatment methods may only worsen the vasospastic reaction. Peripheral intravenous nitroglycerin infusion has often been unsuccessful treatment while intragraft or intracoronary nitroglycerin injection or administration of calcium channel-blocking drugs, or both, has proven to be effective in reversing the coronary artery spasm and ventricular dysfunction. Reluctance to use vasodilating agents must be overcome, even in the face of hypotension, when evidence of spasm is present.

Abstract
To investigate mechanisms of development in ischemic myocardial injury, intracellular pH and high energy phosphates in perfused guinea-pig hearts were monitored by 31P-MRS. Intracellular ATP content decreased to 1.2% and 26.4% of control during 60 minutes global ischemia, respectively with and without preischemic administration of isoproterenol. Intracellular pH declined to 6.48 and 6.03 respectively. Postischemic cardiac function was severely impaired by isoproterenol. ATP breakdown had little influence on intracellular pH in ischemic hearts. It was verified that inotropic agents can progress ischemic myocardial injury, and that contractile recovery is more correlated with the residual ATP level than intracellular pH.

Abstract
The revival of the concept of coronary spasm has stimulated research into coronary artery disease. Observations in patients with variant angina have substantially contributed to the appreciation of painless myocardial ischemia. However, the presence or absence of pain during ischemic episodes is not related to the cause of ischemia, because painless ischemia can be observed in variant angina (caused by spasm), in effort-induced angina (caused by increased myocardial demand) and in myocardial infarction (caused by thrombosis). Continuous monitoring initially of patients with variant angina and subsequently of patients with unstable and stable angina proved that often painful and painless ischemic episodes are caused by a transient impairment of regional coronary blood flow rather than by an excessive increase of myocardial demand. The transient impairment of coronary flow appears to be caused by dynamic stenosis of epicardial coronary arteries. This most often occurs at the site of atherosclerotic plaques encroaching on the lumen to a variable extent. Dynamic stenosis can be caused by 1) "physiologic" increase of coronary tone, as in stable angina, 2) spasm, as in variant angina, and 3) thrombosis, usually in combination with "physiologic" changes in tone or with spasm, or both, as in unstable angina. The mechanisms of spasm, as typically observed in variant angina, are different from those of "physiologic" increase of tone; they appear to be related to a local alteration that makes a segment of coronary artery hyperreactive to a variety of constrictor stimuli causing only minor degrees of constriction in other coronary arteries. The nature of this abnormality, which may remain stable for months and years, is yet unknown.
