Odds ratios (ORs) were estimated for the prevalence of antecedent endocrine, metabolic, or vascular diseases among 45 patients with amyotrophic lateral sclerosis from the Rochester, Minn, population compared with 90 control subjects matched for sex, year of birth, period of observation, and residence. Hypertension occurred less frequently in male patients with amyotrophic lateral sclerosis (4%) than in control subjects (30%; OR = .10). Because of small population size, no conclusions can be drawn with respect to the following antecedent conditions: thyroid disease (OR = 1.61), coronary artery disease (OR = .58), obesity (OR = .52), diabetes (OR = 1.00), cerebrovascular disease (OR = .21), and peripheral vascular disease (OR = 1.23). The heterogeneity of antecedent thyroid disease makes it highly unlikely that any specific thyroid lesion is causally associated with most cases of amyotrophic lateral sclerosis. Hypertension may be a marker for protective factors against the development of amyotrophic lateral sclerosis in men.

In order to determine the effect of obesity on the results of coronary artery bypass graft (CABG) surgery, we compared 250 obese patients undergoing CABG procedures between 1984 and 1987 with 250 age- and sex-matched controls of normal body mass index (BMI) undergoing CABG in the same period. The obese group had a greater incidence of diabetes mellitus (p less than 0.02), hypertension (p less than 0.05), hyperlipidaemia (p less than 0.05), and left main stem coronary artery disease (p less than 0.001). No differences were identified in the surgery performed, but obesity was associated with prolonged total bypass time (p less than 0.05). Operative mortality was 0.8% in both groups. Multivariate analysis demonstrated obesity to be an independent risk factor for perioperative morbidity (p less than 0.05). Univariate: respiratory (p less than 0.01); leg wound (p less than 0.001); myocardial infarction (p less than 0.02); arrhythmias (p less than 0.02); sternal dehiscence (p less than 0.02). At a mean follow-up time of 36.9 months obese patients exhibited a greater incidence of significant recurrent angina (p less than 0.01), which was associated with further weight gain (mean 12.2 kg; linear correlation: p less than 0.001, r = 0.891). Although in CABG surgery operative mortality is not increased in obese patients, aggressive pre- and postoperative weight control is indicated to reduce both perioperative morbidity and the incidence of recurrent angina.

Between 1973 and 1977 169 patients underwent implantation of bifurcated prostheses for arterial occlusive disease. Perioperative and follow-up data 10-14 years after operation were retrospectively assessed. The angiologic status of living patients was compiled. Impact of following risk factors was investigated with multivariant analysis. Coronary artery disease, hypertension, smoking, diabetes mellitus, Pulmonary disease, renal insufficiency, obesity. Follow-up was 98.8%. Preoperatively over 90% of the patients investigated had been in grade IIb (Fontaine) or worse (33% grade IV). Early mortality was 5.3% (1973 = 15%, 1977 = 5.3%, 1987/1988 = 1.8%) and was mainly related to cardiopulmonary factors. Reoperation was necessary in 69 patients (149 procedures, no mortality, 38 amputations). Late mortality was 75% (120 of 160 patients) and mainly due to cardiac problems. The 10-year-actuarial-survival (37%) was reduced due to following combinations of risk factors: Myocardial infarction/smoking/obesity (n = 41) 17%, diabetes/smoking (n = 36) 17% hypertension/myocardial infarction (n = 24) 8%. Clinical condition of the living patients (n = 40) was: 48% grade I, 28% grade IIa, 18% grade IIb, none grade III, 8% grade IV. Long term results following implantation of bifurcated prostheses for arterial occlusive disease show, that quality of life is consistently improved. Reoperation is necessary in almost half of the patients due to the progressive disease. Late mortality is closely related to the underlying arteriosclerosis. Life expectancy of our patients does not significantly differ from the normal population and is probably a sequelae of the close follow-up.

Coronary calcifications appear in advanced atheromatous lesions therefore fluoroscopy is useful for the detection of the atherosclerotic coronary artery disease (Aldrich et al., 1979). However, the detection of coronary calcification by fluoroscopy is difficult in the case of obesity or thick chest wall and also impaired by the background structures including bone and other intrathoracic calcifications. X-ray CT is more advantageous than fluoroscopy in the detection of coronary calcification. It can eliminate the interference from background structures and clearly demonstrates calcified sites of the coronary artery. Therefore, we investigated the clinical usefulness in the detection of coronary calcification with X-ray CT.

American Indians and Alaska Natives (AI/ANs) are experiencing an epidemic of diabetes, increasing rates of coronary artery disease and hypertension, and poor survival rates for breast cancer that are likely partially attributable to the increasing prevalence of obesity over the past generation. Obesity may also contribute to the high rates of gallstones and to adverse outcomes of pregnancy in AI/ANs. Although overall mortality was not associated with obesity in Pima Indians (except in the most obese men), the relationship of obesity to longevity in other AI/AN groups is not known. Further study of the specific health effects of obesity in various groups of AI/ANs are needed. In the meantime, community-based programs to prevent obesity and its sequelae should be implemented in all AI/AN communities.

Risk factors for coronary artery disease in 131 known non-insulin-dependent (type 2) diabetic patients is compared to that in 115 newly diagnosed type 2 diabetic subjects and in 316 non-diabetic patients. The subjects, all Indian men aged 21-60 years, represent consecutive survivors of myocardial infarction and were investigated 3-4 months after their acute episode. A group of 524 healthy Indian men aged 21-60 years were included as controls. Significant differences in parameters measured were noted when all diabetic and non-diabetic patients were compared to the control group. Diabetic patients were older than the non-diabetic patients and with significantly higher frequency of hypertension and hypertriglyceridaemia, whilst smoking and family history of coronary artery disease were elicited more frequently in the non-diabetic patients. Mean concentrations of serum total cholesterol and lipoproteins in the diabetic and non-diabetic men were similar, whereas serum triglyceride concentrations were significantly higher in the diabetic patients. Newly diagnosed and known diabetic patients did not differ with respect to the risk factors examined. Clusters of various combinations of hypertension, obesity, hypertriglyceridaemia and low HDL-cholesterol values were encountered more frequently in diabetic patients when compared to non-diabetic patients, whilst no significant differences were observed when the two groups of diabetic subjects were compared. In conclusion, this study has demonstrated that in men with myocardial infarction there are significant differences between diabetic and non-diabetic patients with respect to certain risk factors. However, newly diagnosed diabetic men have similar risk profiles to their known diabetic counterparts.

Two hundred twenty five anginal symptomatic patients (37-75 years) undergoing selective coronary angiography were studied to clarify the importance of risk factors for coronary artery disease (CAD). Serum lipids, apolipoproteins, fasting blood glucose, hemoglobin A1 and A1c, serum insulin levels, hypertension, smoking and obesity were examined as coronary risk factors in 64 newly diagnosed non-insulin dependent diabetic patients (60 +/- 1 (+/- SE)yr), 88 impaired glucose tolerant (IGT) patients (58 +/- 1 yr) and 73 non-diabetic patients (62 +/- 1 yr). Diabetic and IGT patients showed significantly higher coronary atherosclerosis indices than non-diabetic patients (p less than 0.05). In the diabetic and IGT groups, the plasma triglyceride concentrations were significantly higher in the patients with coronary atherosclerosis (CAS) than in either patients without CAS (p less than 0.05) or non-diabetic patients with CAS (p less than 0.05). The prevalence of hypertension in the diabetic patients with CAS was higher than in the non-diabetic patients with CAS. These data suggest that hypertriglyceridemia and hypertension might be important as risk factors in the development of coronary atherosclerosis in persons with an abnormal glucose tolerance.

To investigate the relationship between the coronary-prone behavior pattern (Type A behavior pattern) and coronary artery disease, 159 patients were evaluated by coronary angiography (CAG) and the coronary-prone behavior pattern score (CBP score) as well as other coronary risk factors (CRFs). The extent of atherosclerosis was quantified by the number of diseased major arteries and by a coronary atherosclerosis score (CAS) based on an original, quantitative scoring system. Age, obesity index, systolic and diastolic blood pressure, total cholesterol and CBP score were significantly higher and HDL cholesterol was significantly lower in the multivessel disease group than in the other group. Age, systolic and diastolic blood pressure, total cholesterol, HDL cholesterol and CBP score were correlated significantly with CAS. On the other hand, there was no significant correlation between these CRFs and the CBP score. These results strongly suggest that the behavior pattern might be an independent CRFs via the promotion of coronary atherosclerosis.

Potent prophylactic immunosuppressive protocols promote the safe withdrawal of corticosteroid maintenance. The benefits of corticosteroid-free maintenance immunosuppression include the absence of the cushingoid habitus, fewer infections, less obesity, and lower serum cholesterol. The incidence of allograft coronary artery disease is not increased by corticosteroid-free maintenance. To assess the long-term effects of corticosteroid-free immunosuppression on allograft function, we compared results of hemodynamic study and noninvasive evaluation over the 2-year follow-up of 57 patients on corticosteroid-free maintenance to 40 patients who required corticosteroid. Age and pretransplantation diagnoses were similar, but a greater percentage of those who required corticosteroid maintenance were female (28% versus 2%, p less than 0.001). Indexes of allograft function were similar in both groups and these indexes included ejection fraction, right atrial pressure, pulmonary artery pressure, pulmonary capillary wedge pressure, cardiac index, left ventricular end-diastolic dimension, and posterior wall thickness. Patient survival was identical in the two groups (98%). These data indicate that corticosteroids can be safely withdrawn with the subsequent early benefits and without compromising long-term allograft function.

Because of discrepancy in interpretation of early diastolic filling indices in normal subjects and hypertensive, we studied the correlations between age and radionuclide angiographic peak filling rate (PFR), doppler echocardiographic early E and late A waves, left ventricular mass (LVM), blood pressure (BP) and ejection fraction (EF) in cautiously screened 30 untreated hypertensive and 30 age paired normal subjects (mean of age 52 +/- 17 ranging from 34 to 78 years). No patient had gross obesity nor coronary artery disease. Univariate analysis revealed strong correlations between LV filling and age in normal (r = -0.82 p less than 0.0001) and hypertensive (r = -0.61 p less than 0.001), with a very significant difference in y intercepts (t = 0.61 p = 10(-6)). LVM correlated poorly with age (r = 0.35 p less than 0.05) but with none of the LV filling indexes. BP correlated with PFR (r = 0.33 p less than 0.05) and A wave (r = 0.44 p less than 0.02) in hypertensive only. After multivariate analysis, significant dependencies of PFR, age, LV mass were more accurate if BP was in a higher range. The variability of the values of LV filling indexes was wider in hypertensive than in normotensive. Normotensive aging and hypertension have similar effects on the cardiovascular system. In the most aged people even without apparent cardiac disease, it is not possible to identify the specific effects of hypertension on diastolic function.
