Emergency coronary angiography in a 28-year-old male suffering an acute anteroseptal myocardial infarction revealed complete obstruction of the left anterior descending artery in association with multiple aneurysms of the 3 major coronary arteries. Successful intracoronary thrombolytic treatment with urokinase infusion directly into the infarct-related artery was performed 2 h after the onset. Follow-up left ventriculogram showed preservation of left ventricular wall motion. Fifty days after the infarction, he underwent aorto-coronary bypass surgery. Histological examination of the biopsy specimen obtained from the aneurysm of the distal portion of the right coronary artery revealed that the 3-layer architecture of the arterial wall had been completely lost. The wall was replaced by fibrotic tissue, with slight mononuclear cell infiltration around the small vessels, but no acute inflammatory reaction or atheromatous change was seen. In spite of the presence of the coronary risk factors of hypertension and hyperlipidemia, angiography revealed no evidence of atherosclerosis of systemic arteries. It is suggested that the coronary aneurysms in this case are possible sequelae of Kawasaki disease in childhood.

Sports-related sudden cardiac deaths were compared with non-sports-related sudden cardiac death in individuals (14 to 40 years old) who were autopsied from 1981 to 1988 at the Maryland Medical Examiner's Office. Thirty-four of 690 total cases of sudden cardiac death were sports-related, which represents 5% of sudden cardiac death in this age group. Causes of death were severe atherosclerosis (nine), hypertrophic cardiomyopathy with asymmetry (eight), coronary artery anomalies (four), idiopathic concentric left ventricular hypertrophy (three), myocarditis (two), arrhythmogenic right ventricle (one), Kawasaki disease (one), and unknown (six); two of the cases with unknown causes had tunnel arteries. Exercise-related deaths were more likely due to hypertrophic cardiomyopathy (p = 0.0007) compared with 102 age-, sex-, and race-matched controls in the non-exercise group; there was no difference in the incidence of severe atherosclerosis (p = 0.4). The mean age of individuals with hypertrophic cardiomyopathy with asymmetry was less than that of those with severe atherosclerosis (24 vs 32 years, p = 0.03). Thus exercise precipitates sudden cardiac death in younger individuals with hypertrophic cardiomyopathy.

The coronary artery lesions in Kawasaki disease (KD) are thought to be a possible risk factor for atherosclerosis in the long term from the pathological point of view. Here we report results of a comparative control study to investigate the distensibility of the coronary artery in KD. A total of 146 patients were divided into 5 groups as follows. (I) Normal group (N); consisting of 44 patients with a known history of KD but with no coronary artery lesion. Among this group of patients those who each showed a regression in their coronary artery aneurysms were divided into 2 subgroups according to the time since onset of KD. (II) A group in the early stage after regression (ER); consisting of 18 patients with a known history of KD followed for 1.8 +/- 0.6 years. (III) A group in the later stage after regression (LR); consisting of 22 patients with a known history of KD followed for 9.4 +/- 2.8 years. (IV) an abnormal group (A); consisting of 21 patients followed for 7.9 +/- 4.0 years with a persistent aneurysm and/or stenosis in a coronary artery at the time of this study. And (V) a control group (C); consisting of 41 patients with a congenital heart disease such as a small ventricular septal defect or mild pulmonary stenosis or patent ductus arteriosus and no history of KD. In each case, the coronary artery diameter was measured by angiography before and after intracoronary infusion of isosorbide dinitrate (ISDN).(ABSTRACT TRUNCATED AT 250 WORDS)

Serum total cholesterol and high-density lipoprotein (HDL) cholesterol concentrations were studied in paired sera from 23 patients (16 boys) with Kawasaki disease (KD) during acute illness and in 35 patients (21 boys) 5.4 to 7.7 years after KD. Total cholesterol and HDL cholesterol concentrations were significantly lower (paired t test, p = 0.0001) in samples taken within 30 days of the onset of illness (3.32 +/- 0.85 mmol/L (128 +/- 33 mg/dl) and 0.54 +/- 0.25 mmol/L (20.8 +/- 9.7 mg/dl) than in the second samples taken 2 to 16 months after onset of disease (4.16 +/- 0.93 mmol/L (161 +/- 35 mg/dl) and 1.24 +/- 0.35 mmol/L (47.2 +/- 13.9 mg/dl). The lowest total cholesterol levels were observed in samples taken 6 to 9 days after the onset of KD (p = 0.019). No correlations were seen between the highest erythrocyte sedimentation rate, C-reactive protein, or thrombocyte counts and the acute or convalescent cholesterol levels. In patients studied 5.4 to 7.7 years after recovery from KD, the mean total cholesterol concentrations were still lower than in healthy Finnish children. In girls the HDL cholesterol concentrations were similar, whereas 3 of the 18 boys studied had HDL cholesterol values more than 2 SDs below the mean for healthy boys. There was no correlation between the serum cholesterol concentrations and coronary artery abnormalities. These data lead us to infer that KD does not cause such permanent changes in cholesterol metabolism as to be considered a risk factor for atherosclerosis beyond that caused by the disease itself.

Kawasaki disease is an acute vasculitis characterized by mucosal inflammation, rash, cervical adenopathy, indurative edema of the hands and feet, and late membranous desquamation of the fingertips. Early cardiac effects include myocarditis (occasionally with congestive heart failure), pericardial inflammation, and, rarely, valve involvement. Coronary artery aneurysms are a long-term concern because coronary thrombosis with myocardial infarction can be a late manifestation. The origin of Kawasaki disease is unknown, but an infectious agent is most likely. Management consists of aspirin for control of fever and inflammatory manifestations and intravenous gamma globulin for the prevention of coronary aneurysm formation. Careful late follow-up is required, especially for patients with persistent coronary abnormalities. Giant aneurysms (greater than 8 mm) are more likely to progress to coronary obstructive disease, and coronary bypass grafts have been required for some patients. Late coronary artery manifestations in patients with mild early coronary dilatation have not been described. However, since long-term epidemiologic studies have not yet been performed, it is prudent to consider childhood Kawasaki disease to be a potential risk factor for coronary disease, especially in atherosclerosis-prone Western societies.

The pathology of five aneurysms resected from four patients with Kawasaki disease was examined to elucidate the mechanisms of regression. (1) Marked intimal thickening was present in all five aneurysms. (2) Two patients treated with aspirin early in their course showed well-regenerated endothelium and marked thickening of the intima without massive thrombus; the thickened intima was rich in smooth muscle cells. These aneurysms maintained an adequate lumen of similar diameter to normal arteries, and some regressed angiographically. (3) Two patients untreated with aspirin in the acute phase had intimal thickening associated with massive thrombus formation and calcification. The pathologic appearances were similar to those of early atherosclerosis. One patient died suddenly of myocardial infarction. We conclude that the angiographically demonstrated phenomenon of aneurysm regression may result from intimal thickening mainly caused by the proliferation of smooth muscle cells not associated with massive thrombus. The thickened intima associated with massive thrombus may cause ischemic heart disease and simulate atherosclerosis. It is possible that the administration of aspirin may prevent massive thrombus formation. We hypothesize that Kawasaki disease may be an etiologic factor in some cases of early atypical coronary atherosclerosis.

Between January 1973 and December 1979, 290 patients with Kawasaki disease were evaluated with coronary angiography after the acute stage of illness. Of these patients, 43 (15 percent) were diagnosed as having coronary aneurysms. Forty-two patients have been followed up for an average of 4 years (range 15 months to 8 years). One 8 month old girl died of myocardial infarction after 4 months of illness. Follow-up coronary angiography was performed in 42 patients 5 to 18 months after the acute illness. Four groups can be distinguished. Group I: In 21 (50 percent) of 42 patients angiography showed that the coronary aneurysms had regressed, so that no observable lesions were seen. During convalescence, electrocardiography, exercise stress testing and thallium scintigraphy were within normal limits. In the other 21 patients abnormal findings persisted on follow-up angiography. Group II: Ten patients showed persistent coronary aneurysms, although reduced in size. Group III: In seven patients the aneurysms had disappeared, but complete obstruction or marked stenosis of coronary arteries was found. Group IV: In four patients, irregularities of the coronary arterial wall without stenosis were seen. Among patients with abnormal angiographic findings myocardial infarction and mitral regurgitation were also seen. Early initiation of aspirin therapy aneurysms show regression on angiography in 1 or 2 years in about half of patients. The remaining patients are at risk for ischemic heart disease. Thus, Kawasaki disease should be considered an important cause of ischemic heart disease in children and a possible risk factor of premature coronary atherosclerosis.

Mucocutaneous lymph node syndrome (MCLS) in the young has been known to have coronary aneurysms, and then it has been recently suspected as a cause of premature atherosclerosis and cardiomyopathy. Thirty-three schoolchildren who suffered from MCLS were studied to evaluate cardiac involvements and left ventricular function using two-dimensional (2-D) echocardiograms and submaximal stress test. Fifteen normal schoolchildren were studied as normal control. All these MCLS children were asymptomatic and had no significant findings in routine chest X-ray and electrocardiographic examinations. According to submaximal stress test, 8 cases showed a J type ST depression of only 0.5--1.0 mm, and there were no positive cases. Using 2-D echocardiograms, the left coronary artery was detected in 85% and the right coronary in 27%. One case showed an aneurysm of the left coronary artery. However, none of them showed abnormal left ventricular wall motion or the wall motion abnormality compatible with cardiomyopathy. There were no significant differences between MCLS and normal control in ejection fraction, mean VCF, diastolic descent rate of the anterior mitral valve, D/S ratio of the left ventricular wall, and Weissler's index (PEP/ET). These findings suggested that 1) most of MCLS schoolchildren do not have obvious cardiac involvement and their left ventricular function is within normal limits, 2) because of its low sensitivity, submaximal stress test is not so useful in screening coronary lesions, and 3) the 2-D echocardiogram works not only in detecting coronary aneurysms but also in evaluating left ventricular function.

Ultrasound is widely used for the diagnosis and follow-up of patients with many kinds of vasculitis. Transcutaneous or transesophageal two-dimensional ultrasound images can depict vascular wall lesions associated with vasculitis such as stenosis, aneurysm or wall thickening. Pulsed Doppler and color Doppler are useful for the assessment of stenoses and changes in blood flow. Recent progress in intravascular ultrasound apparatus made it possible to more precisely assess morphological changes in vascular wall. Intravascular ultrasound of a 27-year old male patient suffering from inferior myocardial infarction with right coronary aneurysms revealed calcification and fibrosis of the intima and early development of atherosclerosis in both right and left coronary arteries suggestive of the sequelae of Kawasaki disease.

Kawasaki disease is an acute febrile illness recognized most often in children under 4 years of age. It is characterized by mucosal inflammation, indurative edema of the hands and feet, skin rash and cervical lymphadenopathy. This is an acute systemic vasculitis syndrome of unknown etiology which has been recognized not only in Japan but all over the world. This article reports on the clinical spectrum of Kawasaki disease, analysis of coronary artery and other lesions, and long-term cardiovascular problems including premature atherosclerosis. The etiology and pathogenesis of this disease are still unknown. Current hypotheses and leading studies on the etiology and the pathogenesis of Kawasaki disease are also reviewed.
