Hypertension is a major risk factor for stroke and heart disease in elderly people. Eighty hypertensive subjects with mild cognitive impairment, aged over 70 years were drawn from a community screening programme and randomized to either captopril 12.5 mg twice daily or bendrofluazide 2.5 mg daily in a double-blind trial. Subjects were excluded if they had previously received antihypertensive treatment or had significant cardiac disease. Electrocardiograms (ECG) were recorded and scored at baseline and after 12 and 24 weeks of treatment. Mean blood pressure fell significantly and equally in both treatment groups. Most ECG variables remained unchanged throughout the trial but a significant reduction in QRS duration from 0.08 to 0.07 seconds was observed with captopril at 12 weeks (p = 0.004) and 24 weeks (p = 0.002). Subjects on captopril also exhibited a significant improvement in overall ECG classification at 12 weeks (p < 0.05), although this was not sustained at 24 weeks (p = 0.076). Captopril is a suitable alternative to bendrofluazide as an antihypertensive drug for elderly people with regard to ECG detected cardiac complications.

During the last few years, the use of angiotensin converting enzyme (ACE) inhibitors in the treatment of patients with cardiovascular diseases has been increasing. Captopril is the earliest oral ACE inhibitor and was marketed in 1977. The adverse effect most undesirable with vasodilators, particularly in patients with heart disease, is a reflex tachycardia. The absence of tachycardia with the possibility of binding free radicals is the comparative advantage of angiotensin converting enzyme inhibitors. Because of their positive hemodynamic effect, ACE inhibitors should be used as a supplement in the treatment of patients who need aortocoronary bypass. Their use does not exclude the intravenous administration of vasodilators, and only decreases the required therapeutic concentration of these drugs.

The novel antihypertensive drugs which have been discovered and developed in the latter half of the 20th century were investigated. Newly discovered or improved drugs are approved by the Ministry of Health and Welfare in Japan, and after then they become available for clinical use. We can follow the progress and trends of various new antihypertensive drugs by recording their years of approval. The four primary useful drugs for the treatment of hypertension were developed were introduced as listed in the following: 1. Antihypertensive diuretics: Thiazide and dihydrothiazide were first approved in 1958, and various related drugs including aldosterone antagonists and loop diuretics followed. 2. beta-Adrenergic-blocking drugs: Propranolol was approved in 1966 for heart diseases and for hypertension in 1970. Thereafter many related drugs were developed. 3. Calcium channel-blocking drugs: Nifedipine was approved, for heart disease in 1974 and for hypertension in 1981, and then many related drugs appeared. 4. Angiotensin-converting enzyme inhibitors: Captopril was approved in 1982 and thereafter various related drugs followed. The four categories of these drugs were selected as first choice drugs for the treatment of hypertension in 1988. The development of these excellent useful drugs affected the mortality rates of cerebrovascular diseases (e.g., apoplexy). The mortality curve reaches plateaued in 1963, peaked in 1965, and then declined rapidly. Antihypertensive diuretic drugs stop the rise of mortality, and beta-blocking drugs, Ca-antagonists and ACE-inhibitors promote rapid downward tendency.

Proven cardiovascular benefit from angiotensin-converting enzyme (ACE) inhibition is a cornerstone of evidence-based medicine. The first study to show dramatic benefits from ACE inhibition was the Cooperative North Scandinavian Enalapril Survival Study (CONSENSUS-I), in which a 31% decrease in the rate of death was observed in patients with severe heart failure at the end of 1 year of enalapril treatment (p = 0.001). This result led to large long-term studies-including Survival and Ventricular Enlargement (SAVE), Acute Infarction Ramipril Efficacy (AIRE), Trandolapril Cardiac Evaluation (TRACE), and Study of Left Ventricular Dysfunction (SOLVD)-which verified that ACE inhibition decreases heart failure, myocardial infarction (MI), and mortality, and that striking benefit could be observed within 30 days. Short-term studies of patients in the acute phase of a heart attack verified that ACE inhibition provided rapid benefits. A meta-analysis of short-term (up to 8 weeks) studies of ACE inhibition (including CONSENSUS-II, Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico [GISSI]-3, International Study of Infarct Survival [ISIS]-4, and the Chinese Captopril Study [CCS]-1) demonstrated that post-MI risk was reduced by 10% within the first day of treatment. The immediacy of the benefit suggested that ACE inhibition not only improved cardiovascular function in failing hearts but also affected important mechanisms in patients without overt heart failure. Effects on more general mechanisms of heart disease suggested that patients with problems other than hypertension or heart failure might benefit from ACE inhibitors. The Heart Outcomes Prevention Evaluation (HOPE) study investigated the hypothesis that ACE inhibition would confer benefits to patients who were at high risk for cardiovascular events, but who were without left ventricular dysfunction or heart failure. Long-term reductions in MI, stroke, cardiac arrest, and heart failure, as well as improvements in mortality, were observed in this population after treatment with ACE inhibitors. Substudies of the HOPE study revealed that ACE inhibition reduced progression of atherosclerosis and improved myocardial remodeling. Taken together, these studies provide evidence that supports treatment of a broad population of patients at risk for cardiovascular events with ACE inhibitors. The next step is to combine ACE inhibition with other treatments to maximize patient benefit. The Ongoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET) will compare the efficacy of an ACE inhibitor (ramipril) with an angiotensin receptor blocker (telmisartan), and determine whether these treatments in combination will further reduce morbidity and mortality from cardiovascular disease.

This study included 40 children, who were diagnosed with pneumonia and pulmonary hypertension (from the radiographic and clinical features), was performed at Yuzuncu Yil University Faculty of Medicine, Department of Pediatrics, from September 2003 to July 2005. Patients who had pneumonia and congenital heart disease or systemic hypertension or renal and liver disease together were excluded from the study. Blood gas analysis and oxygen concentration, measured with pulse oximetry, were performed in all patients. Besides chest X-ray, electrocardiography and echocardiographic search was also carried out. Echocardiographic examination was performed by using M mode, two-dimensional echocardiography and colored Doppler sonotron Vingmed CFM 725. At echocardiographic examination, pulmonary hypertension is defined as above 35 mmHg of pulmonary artery pressure. For echocardiographic examination, patients with pulmonary hypertension were divided into two groups. Captopril (2 mg/kg/day, three doses a day) and nifedipine (0.5 mg/kg/day, three doses a day) were given to the first and the second group, respectively. Echocardiography was performed daily until normal pulmonary artery pressure was achieved. At the beginning of the treatment, the patients were treated with double antibiotics and antibiotic change was carried out in needed cases at the follow up. Digoxin was administered to the cases of respiratory infection with heart failure.
