Hypertension 2005: an evidence-based approach to diagnosis and treatment – an American perspective

A novel management program for hypertension

In this article, we describe a comprehensive management program for hypertension (HTN), based on the experience of leading cardiovascular centers in China. This comprehensive approach, adhering to a number of core principles, includes diagnosis and therapeutic interventions. Therapeutic management includes lifestyle changes, risk factor management and pharmacological intervention and should allow reliable lowering blood pressure (BP). Additional paragraphs discuss the relationship between paroxysmal atrial fibrillation (PAF), and HTN.

New standards in hypertension and cardiovascular risk management: focus on telmisartan

Blockade of the renin–angiotensin system is an important approach in managing high blood pressure, and has increasingly been shown to affect cardiovascular disease processes mediated by angiotensin II throughout the cardiovascular and renal continua. Telmisartan is an angiotensin II receptor blocker (ARB) displaying unique pharmacologic properties, including a longer half life than any other ARB, that result in large and sustained reductions of blood pressure. In patients with mild-to-moderate hypertension, telmisartan has proved superior to other antihypertensive agents (valsartan, losartan, ramipril, perindopril, and atenolol) in controlling blood pressure particularly towards the end of the dosing interval. There is also clinical evidence that telmisartan reduces left ventricular hypertrophy, reduces arterial stiffness and the recurrence of atrial fibrillation, and confers renoprotection. The ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET^®) study has demonstrated that telmisartan has similar cardiovascular protective effects to ramipril in a large, high-risk patient population but was better tolerated. The powerful and sustained blood pressure control apparent in clinical trials, together with cardiovascular protection and tolerability demonstrated in ONTARGET^® means that telmisartan may be a preferred option for patients with hypertension.

Severity, control, and responsiveness in asthma

Guidelines for asthma management have proposed that initial treatment should be based on assessment of asthma severity. The treatments proposed for different degrees of asthma severity are essentially estimates of the intensity of treatment needed to achieve asthma control. Responsiveness to treatment is heterogeneous, however, even among asthmatic patients with asthma of similar severity. This heterogeneity calls attention to the importance of assessing asthma control and adjusting treatment accordingly. Application of a guidelines-based approach to asthma management thus requires general agreement on what is meant by severity, control, and responsiveness and requires further an awareness of asthma as causing symptoms and functional impairment in the present and also as causing risk of adverse events in the future.
