Cardiovascular mortality and morbidity were assessed, after a mean follow-up period of 5 years, in an unselected series of 159 adults presenting with the nephrotic syndrome between 1972 and 1975. 60% of the deaths were attributed to terminal renal failure, and the incidence of deaths from ischaemic heart-disease (IHD) was not significantly above normal. The proportion of patients experiencing angina and intermittent claudication and the prevalence of ischaemic electrocardiographic changes did not differ significantly from those of a London control population. At follow-up, hypertension was significantly more common (p less than 0.001) in male nephrotic patients than in controls. Earlier reports of a greatly increased incidence of IHD in unselected patients with the nephrotic syndrome were not confirmed. Routine treatment of hyperlipidaemia in the nephrotic syndrome is not, therefore, recommended.

In 14 of 204 consecutive cadaveric renal allograft recipients, the primary diagnosis was essential hypertension. Four patients had manifest ischemic heart disease before transplantation. Three of these patients died within 31 months of transplantation from recurrent myocardial infarction, and the fourth experienced coronary insufficiency. Cadaveric renal transplantation does not prevent the progression of coronary artery disease in patients whose renal failure was due to essential hypertension. In the presence of angina or previous myocardial infarction, these patiemts may be better treated by maintenance hemodialysis.

In order to evaluate whether and to what extent elevated blood lipid concentrations and clinical expressions of coronary heart disease (CHD) are associated in the elderly, we studied the risk of CHD (myocardial infarction and angina pectoris) in a population of elderly hospitalized patients (210 subjects, 126 men and 84 women, average age 76 +/- 6 years) exposed to risk factors. 210 patients, free from current and previous cardiovascular diseases, age and sex matched, were recruited as the control group. Advanced senile decline, severe hepatic or renal failure and malignancies were considered exclusion criteria for both groups. The following dichotomic variables (familial history of CHD, cigarette smoking, clinical history of arterial hypertension or diabetes mellitus, hypercholesterolemia, hypertriglyceridemia) and continuous variables (total, LDL and HDL cholesterol, triglycerides, total/HDL cholesterol ratio, body mass index (BMI), years of exposure to risk factors) were considered. Using a stepwise multiple logistic regression forward method, the following variables resulted significantly associated with the risk of CHD: total/HDL cholesterol ratio (OR 1,89), BMI (OR 1,04), period of hypertension (OR 1,04) and cigarette smoke exposure (OR 1,007). We conclude that in the elderly the total/HDL cholesterol ratio can be a more predictive and reliable index of coronary risk than blood total cholesterol concentration.

The pharmacokinetics of oral nicorandil 20 mg 12 hourly for 9 doses was evaluated in 21 hospitalized patients with angina pectoris due to coronary heart disease and with normal and impaired renal function. Patients were divided into 3 groups based on creatinine clearance (CLCr): GROUP I (n = 6) greater than 80 ml/min, GROUP II (n = 8) 20-80 ml/min, and GROUP III (n = 7) less than 20 ml/min. After the first dose, the total clearance of nicorandil (CL) value did not change with increasing renal failure and so was not dependent on creatine clearance. After the last dose CL was 51 l.h-1 in Group I, 44 l.h-1 in Group II and 56 l.h-1 in Group III, and it was not related to creatinine clearance. The percentage of the dose excreted in the urine was 0.4%. No significant difference was noted in any of the other pharmacokinetic parameters examined in the three groups, not even on comparing values obtained on the first and last days of treatment. The findings suggest that there is no need to change the dose of nicorandil in subjects with different degrees of renal failure.

Cardiovascular diseases are a leading cause of death in end-stage renal disease (ESRD) largely as a result of the progressively increasing age of ESRD patients and the broad constellation of uremia-associated factors that can adversely affect cardiac function. Hypertension, one of the leading causes of renal failure, is a major culprit in this process, causing left ventricular hypertrophy, cardiac chamber dilation, increased left ventricular wall stress, redistribution of coronary blood flow, reduced coronary artery vasodilator reserve, ischemia, myocardial fibrosis, heart failure, and arrhythmias. In addition to impairing the coronary microcirculation, hypertension may contribute to the development of atherosclerotic coronary artery disease, particularly in the presence of the many lipid abnormalities observed in ESRD. These patients have reduced high-density lipoprotein cholesterol and increased plasma triglyceride concentrations, and there is a defect in cholesterol transport. Other abnormalities that may contribute to atherosclerotic coronary artery disease in ESRD are reduced high-density lipoprotein cholesterol synthesis and reduced activity of the reverse cholesterol pathway. Treatment with fibric acids, nicotinic acids, and lovastatin may be useful in lowering cholesterol and triglyceride concentrations in some of these patients. The incidence of coronary artery disease in ESRD populations is difficult to determine. About 25 to 30% of ESRD patients with angina have no evidence of significant coronary artery disease, and an undetermined number have silent coronary disease. The presence of resting electrocardiographic abnormalities caused by hypertension or conduction defects makes it difficult to accurately diagnosis coronary artery disease in ESRD populations by noninvasive methods, including exercise testing and thallium scintigraphy with or without the use of dipyridamole. Hypotension is a frequent complication of the dialytic process. Many factors have been implicated, including autonomic neuropathy. There is no consensus on the function of the efferent limb of the sympathetic nervous system. The afferent limb (arterial baroreflex function) is felt to be impaired. Further, there may be defects in the ability of the cardiovascular system to respond to sympathetic nerve activity. Most studies of autonomic function have used indirect measurements. Studies are underway that use techniques to assess sympathetic function directly. Such experiments with microneuropathy suggest greater skeletal sympathetic muscle discharge in uremic patients than in normal patients.

The UK Prospective Diabetes Study (UKPDS) is a multi-centre, prospective, randomised, intervention trial of 5100 newly-diagnosed patients with Type 2 (non-insulin-dependent) diabetes mellitus which aims to determine whether improved blood glucose control will prevent complications and reduce the associated morbidity and mortality. Newly presenting Type 2 diabetic patients aged 25-65 years inclusive, median age 53 years, median body mass index 28 kg/m2 and median fasting plasma glucose 11.3 mmol/l, were recruited and treated initially by diet. Ninety five percent remained hyperglycaemic (fasting plasma glucose greater than 6 mmol/l) and were randomly allocated to different therapies. In the main randomisation, those who were asymptomatic and had fasting plasma glucose under 15 mmol/l were allocated either to diet policy, or to active policy with either insulin or sulphonylurea aiming to reduce the fasting plasma glucose to under 6 mmol/l. Over 3 years, the median fasting plasma glucose in those allocated to diet policy was 8.9 mmol/l compared with 7.0 mmol/l in those allocated to active policy. The Hypertension in Diabetes Study has been included in a factorial design to assess whether improved blood pressure control will be advantageous. Patients with blood pressure greater than or equal to 160/90 mm Hg were randomly allocated to tight control aiming for less than 150/85 mm Hg with either an angiotensin-converting enzyme inhibitor or a Beta-blocker or to less tight control aiming for less than 200/105 mm Hg. The endpoints of the studies are major clinical events which affect the life and well-being of patients, such as heart attacks, angina, strokes, amputations, blindness and renal failure. To date, 728 patients have had at least one clinical endpoint. Surrogate endpoints include indices of macrovascular and microvascular disease detected by ECG with Minnesota Coding, retinal colour photography and microalbuminuria. The studies also aim to evaluate potential risk factors for the development of diabetic complications such as smoking, obesity, central adiposity, plasma LDL- and HDL-cholesterol, triglyceride, insulin, urate and other biochemical variables. The studies are planned to terminate in 1994, with a median follow-up of 9 years (range 3-16 years) for the glucose study and 5 years (range 2-6 years) for the hypertension study.

Percutaneous transluminal coronary and renal angioplasty (PTA and Renal PTA) were performed during the same procedure in five of 100 patients who underwent PTCA between August 1989 and June 1990. All patients were male, with systemic hypertension (HT) with angina grade I to IV. The median age was 62 years (range 53 to 74). Three patients had controlled HT with 2 to 4 drugs and 2 were uncontrolled even after multiple antihypertensive treatment. Two patients were diabetic and the serum creatinine levels were normal except in one patient (1.9 mg/dL). Lesions more than 70% obstruction of luminal diameter were approached. Multivessel PTCA was done in one patient, multi-lesion in 2 and single lesion in other two. A total of 11 lesions were dilated, 4 in LAD, 5 in Cx and 2 in RCA (type A = 2, type B = 9). Complete revascularization was achieved in all cases. Five renal lesions were approached, 4 in the proximal third and one on the middle third. In 2 patients the blood pressure (BP) fell within normal limits without medication. In other 2 there was an improvement and were easily controlled with just one drug. One patient had no improvement and required multiple therapy to control it. The only complication observed was in a diabetic with previous abnormal serum creatinine who developed non-oliguric renal failure and returned to basal creatinine level at the third day post PTCA. In selected cases PTCA and renal PTA can be safely performed during the same procedure, with the advantage of cost reduction.

We treated 34 primary lung cancer patients with chemotherapy of cisplatin and etoposide. There were 2 cases of CR (15%) and 8 cases of PR (61%) out of 13 cases of small cell lung cancer. No case of CR and one case of PR (5%) were obtained out of 21 cases of non-small cell cancer. Side effects were leukopenia, increase of BUN and creatinine, angina pectoris, supraventricular premature contraction, and renal failure. WBC reached nadir on day 15 on average. When we repeated this regimen, we encountered 3 cases of acute myocardial infarction, and it was useful for small cell lung cancer.

The prevalence of hypertension increases with age. The majority of the hypertensive population is over age 55. Although the treatment of systolic hypertension remains incompletely understood, the reduction of diastolic hypertension with pharmacotherapy has been shown to reduce complications from hypertension in persons over age 55. The older hypertensive patient is at risk for the same complications as the younger patient: angina, myocardial infarction, arteriosclerosis obliterans, stroke, myocardial hypertrophy, congestive heart failure, and renal failure; the risk of sudden death and multi-infarct dementia in the older patient may be somewhat higher. The older hypertensive individual may have reduced plasma volume and defective salt and water conservation, reduced renal function, impairment of baroreceptor reflexes and sympathetic reactivity, and altered drug pharmacokinetics, or may have arteriosclerosis leading to pseudohypertension. Many circumstances interfere with adequate compliance with therapeutic regimens among the elderly. Concomitant medical conditions increase the possibility of drug interactions and require that the practitioner be able to adjust the antihypertensive program to the patient.

We have performed coronary bypass grafting in 25 patients 80 years of age or more. The patients' preoperative conditions were characterized by recent myocardial infarction (16/25, or 64%), obesity (15/25, or 60%), hypertension (14/25, or 56%), and left ventricular dysfunction (21/25, or 84%). There were no deaths in the hospital or within 30 days of operation (0/25, or 0%). Postoperative complications occurred in five cases (20%). Complications were leg incision infection (2/25, or 8%), urinary tract infection (1/25, or 4%), stroke (1/25, or 4%), and transient neurologic deficit (1/25, or 4%). There were no instances of reoperation for bleeding, perioperative myocardial infarction, renal failure, pulmonary failure, intraaortic balloon pump use, or sternotomy infection in these patients. Eleven patients (44%) were hospitalized for fewer than 10 days after operation, and all but two (23/25, or 92%) were discharged within 20 days after operation. All patients were followed up, and survival and New York Heart Association functional class were determined. Cumulative survival rate was 94% at 1 year and 88% at 5 years. The cumulative percent survival rate with class I or II function was 92% at 1 year and 80% at 5 years. No patient had recurrent angina.
