Abstract
The pathogenesis, clinical features, diagnosis, and treatment of spasm of epicardial coronary arteries are reviewed briefly, especially with regard to some issues that remain controversial. For diagnosis, emphasis is placed on the need for objective observations during an attack, even if that requires an attempt at pharmacologic provocation during coronary arteriography, or during echocardiography when prior arteriography has demonstrated the absence of severe coronary stenosis.

Abstract
Coronary angioplasty is reported to be feasible and safe in patients with coronary spasm and fixed stenosis. However, the long-term results are not positive. We compared the results of coronary angioplasty in 20 patients with variant angina versus 17 patients with non-variant angina among 231 consecutive patients with vasospastic angina. Coronary angioplasty was performed successfully in all 37 patients without any complications. Stenting for coronary dissection or recoil was performed in 8 patients, directional coronary atherectomy was selected for ostial lesion of left anterior descending coronary artery stenosis in 2 patients, and standard balloon angioplasty was performed in 27 patients. There were no clinical differences between the two groups. The restensois rate in patients with variant angina was similar to that in patients with non-variant angina (30% vs 29%, ns). There was no relationship between the provoked spasm and restenosis. During the follow-up period, no major complications were observed in patients with variant angina or those with non-variant angina. In conclusion, full medication with calcium channel antagonists and isosorbide dinitrate, and treatment by coronary angioplasty including the use of new devices, were useful treatments for patients with coronary vasospasm and significant organic stenosis. There was no difference concerning the results of coronary intervention between the patients with variant angina and those with non-variant angina.

Abstract
Although the long-term survival of patients suffering from coronary spasm is usually excellent, serious complications can develop, such as disabling pain, myocardial infarction, ventricular tachyarrhythmias, atrioventricular block and sudden cardiac death. A 40-year-old man who had intractable chest pain from coronary artery spasm suffered ventricular fibrillation and an acute anterior myocardial infarction upon first admission. The patient underwent a coronary angiogram, which revealed a spontaneous focal spasm at the proximal left anterior descending coronary artery (LAD). He was treated by the combination of nitrate and calcium channel blocker, but continued to complain of severe chest pain despite intensive medical therapy and he had to be treated in the emergency room 5 times during an 8-month follow-up period. An ergonovine coronary angiogram was performed and an intracoronary ultrasound examination, which revealed a focal spasm at the same site of the proximal LAD with a small amount of localized eccentric atheromatous plaque. A coronary artery stent was placed in the proximal LAD and his symptoms resolved. A follow-up coronary angiogram was performed 3 years after stenting and the stent remained patent without any in-stent restenosis or spasm.

Abstract
A 34-year-old man presenting with angina both at rest and on exertion was investigated. He developed severe ST segment elevation and a brief period of ventricular tachycardia during an exercise tolerance test. On coronary angiography, 60% fixed luminal narrowing was observed in the proximal left anterior descending coronary artery and a severe spasm developed at this site, leading to temporary total occlusion of the vessel. Successful coronary angioplasty (PTCA) was performed on this lesion, with a residual 15% narrowing. However, the patient had a recurrence of angina 3 weeks later, despite being administered high doses of nitrate and calcium antagonist. During control angiography, the lesion severity was unchanged, but spasm developed again following contrast injection. At this time, a Palmaz-Schatz stent was implanted. Calcium antagonist, nitrate, Ticlopidine and low molecular weight heparin therapy was started. There was no recurrence of symptoms during a 3-month follow-up. The exercise tolerance test, and myocardial perfusion scintigraphy findings were normal and the stent was patent without restenosis at the end of the 3-month follow-up. Intracoronary stent implantation for persistent coronary spasm refractory to conventional medical therapy can be considered a feasible and attractive treatment modality for the control of symptoms.

Abstract
BACKGROUND Coronary angiography has been used to assess the anatomy of coronary artery and intraluminal pathological changes. However, it has several limitations in its diagnostic quality and sensitivity in the detection of intraluminal details. Angioscopy has enabled coronary artery lumens to be visualized directly and fine intraluminal morphological changes to be detected. The information obtained by angioscopy is expected to provide new insights into the mechanisms and pathophysiology of transluminal coronary angioplasty. METHODS AND RESULTS Forty-seven patients (39 men and 8 women) with stable angina were enrolled in the present study. Angioscopy was performed before and after angioplasty with a 0.68-mm angioscope with a double-guiding catheter system. The patients who were successfully evaluated by angioscopy were divided into two groups according to the color of the lesion: group 1, mainly yellow; and group 2, white. Angiographic, angioscopic, and clinical parameters in the two groups were compared. Detailed angioscopic findings were obtained in 36 of the 47 patients (77%) before percutaneous transluminal coronary angioplasty (PTCA) and in 24 of the 47 (51%) after PTCA. Yellow plaque were found in 13 of 36 (36%). Age, sex, presence of coronary risk factors, serum cholesterol level, and duration of angina showed no correlation with plaque color. The incidence rates of dissection and thrombi after angioplasty also were not different. Successful dilatation was achieved in 13 of 13 patients (100%) in group 1 and in 21 of 23 (91%) in group 2. The restenosis rate of group 1 was significantly lower than that in group 2 (16.7% versus 57.9%, P < .05). Cox proportional hazards model revealed that plaque color was the independent variable associated with restenosis after PTCA (P = .03). CONCLUSIONS The restenosis rate after successful balloon angioplasty differs, with the color of the target lesion being significantly higher in patients with solely white plaque. Therefore, angioscopic findings are highly predictive of restenosis.

Abstract
Percutaneous transluminal coronary angioplasty has become the treatment of choice for many patients with symptomatic coronary artery disease. Increased experience with the procedure and improvements in equipment have resulted in high initial success rates; however, a significant number of patients develop restenosis. Insights into the pathophysiologic mechanisms of restenosis have led to the use of various pharmacologic agents and devices to prevent its occurrence. Although many have been successful in decreasing the incidence of restenosis in animal studies, none has yet proven successful in decreasing the incidence of restenosis in humans. Newer approaches and novel therapies are needed to prevent restenosis after percutaneous transluminal coronary angioplasty.

Abstract
OBJECTIVES The purpose of this study was to determine whether variables shown to correlate with restenosis in one group (learning group) could be shown to predict recurrent stenosis in a second group (validation group). BACKGROUND Restenosis remains a critical limitation after percutaneous transluminal coronary angioplasty. Although several clinical variables have been shown to correlate with restenosis, there are few data concerning attempts to predict recurrent stenosis. METHODS The source of data was the clinical data base at Emory University. Patients who had had previous coronary surgery and patients who underwent coronary angioplasty in the setting of acute myocardial infarction were excluded. A total of 4,006 patients with angiographic restudy after successful angioplasty were identified. They were classified into a learning group of 2,500 patients and a validation group of 1,506 patients. The correlates of restenosis in the learning group were determined by stepwise logistic regression, and a model was developed to predict the probability of restenosis and was tested in the validation group. By using various cut points for the predicted probability of restenosis, a receiver operating characteristic curve was created. Goodness of fit of the model was evaluated by comparing average predicted probabilities with average observed probabilities within subgroups on the basis of risk level determined by linear regression analysis. RESULTS In the learning group 1,145 patients had restenosis and 1,355 did not. Correlates of restenosis were severe angina, severe diameter stenosis before angioplasty, left anterior descending coronary artery dilation, diabetes, greater diameter stenosis after angioplasty, hypertension, absence of an intimal tear, eccentric morphology and older patient age. The model derived from the learning group was used to predict restenosis in the validation group. By varying the cut point for the predicted probability of restenosis above which restenosis is diagnosed and below which it is not, a receiver operating characteristic curve was created. The curve was close to the line of identity, reflecting a poor predictive ability. However, the model was shown to fit well with the predicted probability of restenosis correlating well with the observed probability (r = 0.98, p = 0.0001). CONCLUSIONS Clinical variables provide limited ability to predict definitively whether a particular patient will have restenosis. However, the current model may be used to predict the probability of restenosis, with some uncertainty, at least in well characterized patients who have already had angioplasty.

Abstract
BACKGROUND High rates of restenosis after coronary angioplasty have been reported in patients with vasospastic angina. This study was designed to determine whether the occurrence of abnormal coronary vasoconstriction, detected by means of hyperventilation testing before angioplasty, influences the risk of restenosis after successful dilation. METHODS Hyperventilation testing was performed 0 to 4 days before coronary angioplasty in 106 consecutive patients with unstable angina and single-vessel coronary artery disease. Abnormal coronary vasoconstriction was considered present if hyperventilation-induced myocardial ischemia occurred during the recovery phase of the test. All patients had follow-up angiography 8 to 12 months after angioplasty. RESULTS Abnormal coronary vasoconstriction was observed in 48 patients (group 1), whereas 58 patients (group 2) had either a negative response throughout the test or a positive response only during the overbreathing phase of the hyperventilation test. Angioplasty was successful in 40 patients in group 1 and 51 in group 2. Restenosis was documented in 29 patients (73 percent) in group 1 and 13 (25 percent) in group 2 (relative risk of restenosis, 2.84; 95 percent confidence interval, 1.69 to 4.28; P less than 0.001). In a multivariate analysis, the following three characteristics were independently related to the risk of restenosis (in descending order of importance): ST-segment elevation during spontaneous ischemic attacks (P less than 0.001), hyperventilation-induced abnormal coronary vasoconstriction (P less than 0.001), and the presence of a lesion more than 10 mm long in the left anterior descending coronary artery (P less than 0.05). CONCLUSIONS In patients with unstable angina and single-vessel coronary artery disease who have been selected for coronary angioplasty, the presence of hyperventilation-induced abnormal coronary vasoconstriction identifies a subgroup at high risk for restenosis.

Abstract
As part of a randomized prospective study designed to investigate the restenosis process after percutaneous transluminal coronary angioplasty (PTCA), the relation between patient-related variables and restenosis rate was examined. A total of 722 patients had successful PTCA. Angiographic follow-up was scheduled for 6 +/- 2 months after the procedure and achieved in 510 patients (71%), yielding 598 lesions for analysis. The overall restenosis rate was 40%. The rate was higher in patients undergoing early restudy for a clinical event than in those undergoing routinely scheduled follow-up restudy (71 vs 22%, p less than 0.0001). Age, sex, cigarette smoking history, diabetes mellitus and history of previous myocardial infarction were not associated with restenosis rate. Angina duration and severity before PTCA were also unrelated to restenosis rate. In summary, these variables, many of which have been previously implicated in restenosis, were not found to be predictors of restenosis. The decision to perform PTCA in individual patients should not be negatively influenced by the presence of these factors.

Abstract
Over the last decade, percutaneous transluminal coronary angioplasty has become a major therapeutic technique of myocardial revascularization. Advances in catheter design and operator experience have made angioplasty a viable alternative for many patients with both single- and multivessel disease who would otherwise require bypass surgery. Acute closure and restenosis remain the 2 principal limitations of angioplasty. Means of controlling these problems, including intracoronary stenting and antiplatelet and thrombolytic agents, are now being studied. Furthermore, controlled prospective randomized trials are underway to assess the value of angioplasty compared with coronary bypass surgery in the treatment of multivessel disease. These trials will help to establish the limits of coronary angioplasty and its relative advantages in terms of therapeutic results and costs.

Abstract
We studied the incidence of spontaneous and ergonovine-induced coronary arterial spasm during repeat coronary angiography in 96 consecutive patients with single-vessel disease who had undergone successful angioplasty. Follow-up angiography was performed after a mean of 6 months (1-8 months). Sixty patients demonstrated no restenosis and in 36 patients restenosis (greater than 50% restenosis) occurred. Spasms of the arteries at the site of dilatation were significantly (P less than 0.001) more frequent in patients with restenosis (18/36; 50%) than in patients without restenosis (4/60; 7%). Before angioplasty, no differences were found in the clinical characteristics between the two groups. Likewise, the morphologic results of angioplasty were identical. Despite long-term treatment with nifedipine (30-60 mg daily) and aspirin (0.5 g daily), 14 of 18 patients with restenosis and coronary spasm suffered from spontaneous angina, as compared to only 3 of 18 patients with restenosis without demonstrable spasm. Three of the 4 patients without restenosis but with detectable spasm were also symptomatic. Thus our findings suggest that spasm of the coronary arteries achieves some importance as a pathophysiological factor for recurrence following coronary angioplasty.
