The aim in treatment of hypertension is normalization of blood pressure. The impact of treatment of hypertension on the development of IHD depends not only on the treatment of hypertension but also on influencing other basic risk factors, i.e. hyperlipoproteinaemia and smoking. Treatment of hypertension can be and should be individual and depends on a) age, b) the level of hypertension, c) complications of hypertension and d) the presence of other diseases, in particular hyperlipoproteinaemia and diabetes mellitus. The treatment of choice in hyperlipoproteinaemia are calcium antagonists, prazosin, ACE inhibitors and beta-blockers with ISA. There is experimental evidence suggesting that calcium antagonists (in particular isradipine) but also beta-blockers suppress the progression of atherosclerosis and AGE inhibitors prevent the development of cardiac and vascular hypertrophy. Effective treatment leads to a decline in the mortality from cerebrovascular attacks--in the USA in the course of 20 years a decline by 60%--in Czechoslovakia so far the mortality from cerebrovascular disease did not change which indicates unfortunately a very poor control of hypertension in the population.

Within the last decade it became obvious that the treatment of angina pectoris alone is not sufficient. Modern goals include the optimization of anti-ischemic treatment ("silent myocardial ischemia") without compromising quality of life, as well as the reduction of fatal and non-fatal cardiac events. The failure of nitrates to continuously protect from myocardial ischemia ("nitrate tolerance") requires a modification of the current step-care recommendations for medical treatment. Numerous combinations of nitrates, betablockers and calcium channel blockers compensate for each other regarding their effects on heart rate, contractility, peripheral resistance and coronary blood flow. Recommendations for combination therapy decisively depend on the choice of the first-line drug. Only nitrates reduce myocardial preload by venodilation and substitute for EDRF-deficiency. After headaches disappear, nitrates do not affect quality of life and they are cheap. The nitrate-induced acceleration of heart rate should be compensated by the addition of beta-blockers or heart rate-decreasing calcium channel blockers. Therefore, the combination of nitrates with heart-rate-increasing calcium channel blockers, such as nifedipine, should be avoided. Many studies have proven the superiority of different double and triple therapies, as compared to their single components. A few reports, however, did not confirm this increase of anti-ischemic efficacy with combination therapy. The improvement of prognosis is proven for beta blockers without ISA in subgroups of patients with acute or post myocardial infarction and can be assumed for nitrates as well. With regard to prognosis, calcium channel blockers were inferior to nitrates and beta blockers. The combination of nitrates with a non-ISA betablocker should be preferred in post myocardial infarction patients with ventricular arrhythmias, whereas the combination of nitrates with a heart rate decreasing calcium channel blocker should be preferred in patients with COPD, severe peripheral arterial disease or severe diabetes. The combination of nitrates with a heart-rate-increasing calcium channel blocker should be considered in patients with sinus bradycardia, first degree AV-block, or proven coronary spasm. In patients with congestive heart failure, betablockers and calcium channel blockers should be avoided. To optimize medical treatment of ischemic heart disease, intermittent high dosage ISDN plus a beta blocker without ISA or ISDN plus a calcium channel blocker like verapamil are recommended. Frequently, however, the patient decides by himself, based on unacceptable side effects.

The submitted review draws attention to advantages and pitfalls of the use of betablockers in the treatment of arterial hypertension. Despite certain metabolically adverse effects which are reduced to a minimum in small doses and more recent betablockers, the latter are along with diuretics the only antihypertensive agents where unequivocally the the long-term favourable effect on the general and cardiovascular mortality was proved. In other hypertensive agents results are expected after completion of multicentric studies which are underway. Beta-blockers, as monotherapy or combined with other drugs, are the drug of choice in the treatment of essential hypertension in young hypertonic patients with hyperkinetic circulation, a tendency for tachycardia, in hypertonic patients with ischaemic heart disease after myocardial infarction or with angina pectoris. In these subjects they quite obviously reduce the general as well as cardiovascular mortality, sudden death and myocardial re-infarction. Betablockers are effective also in elderly hypertonic patients where preparations with ISA or beta 1-selective preparations are more useful. With a certain amount of care similar types of beta-blockers or beta-blockers with a dual effect can be used in hypertension associated with diabetes mellitus, hyperlipoproteinaemia or ischaemia of the lower extremities. Beta-blockers are irreplaceable among antihypertensives of first choice and are experiencing their revival being effective, safe, cheap and well tolerated antihypertensive drugs. Their other properties such as the degree of selectivity, the presence of internal sympathetic activity, combined dual effect, lipophilic or hydrophilic character, enable us to indicate different preparations "tailored" with regard to the severity of hypertension, organ complications and associated diseases.

Ischemic preconditioning (IP) and prior exposure to lipopolysaccharides (LPS) reduce infarct size (IS) and serum tumor necrosis factor-alpha (TNF-alpha) concentration resulting from myocardial ischemia-reperfusion in rabbits. The decrease in TNF-alpha might relate to an induced TNF-alpha inhibitory serum activity (TNF-alpha-ISA). We analyzed TNF-alpha and TNF-alpha-ISA during 30 and 180 min ischemia and reperfusion, respectively, in anesthetized rabbits either untreated (group 1, n = 7), preconditioned (5 and 10 min ischemia and reperfusion, respectively, group 2, n = 9), or exposed to LPS 72 h before ischemia (group 3, n = 9). TNF-alpha-ISA was assessed by coincubating LPS-stimulated rabbit blood with serum of groups 1-3 and measuring TNF-alpha (WEHI assay). With a comparable area at risk, IS in group 1 was 36.9 +/- 11.1 (SD)%, and it was reduced to 13.1 +/- 11.6% and 17.3 +/- 11.3% (both P < 0.05) in groups 2 and 3, respectively. TNF-alpha was increased during ischemia-reperfusion in group 1 but remained unchanged in rabbits subjected to IP or LPS. TNF-alpha-ISA was detected during ischemia-reperfusion in group 2 (29% and 38% of maximum inhibition, respectively) and during baseline, ischemia and reperfusion in group 3 (51%, 46%, 48% of maximum inhibition, respectively) but was absent in group 1. Cardioprotection by IP and LPS is associated with a reduced TNF-alpha and an induced TNF-alpha-ISA during ischemia-reperfusion.

The impact of some types of antihypertensives on carbohydrate metabolism and their association with type 2 diabetes is well-known. In this respect, ACE inhibitors, AT1 blockers or I1 imidazoline agonists, known to improve insulin sensitivity, are the first line therapeutic choice. Metabolism-neutral calcium channel blockers, particularly the dihydropyridines, are the second in line of therapeutic options. On the other hand, beta-blockers and diuretics, thiazide in particular, exert negative effect on carbohydrate metabolism. Should their use be still desirable, e.g. due to co-morbidities, it is advisable to select cardio-selective beta-blockers or beta-blockers with ISA activity, since the effect of these agents on carbohydrate and lipid metabolism is less significant. Diuretics should then be used only in combination therapy and in small doses; potassium-sparing or metabolically neutral indapamide derivatives should be selected. The benefit of cardioprotectivity, gained from the treatment with cardioselective beta-blockers will, particularly in patients with ischemic heart disease, usually outweigh the risk of metabolic adverse effects. Combination therapy, using AT1 blockers or ACE inhibitors in combination with calcium channel blockers or diuretics, should be utilized to its full potential in order to ensure that target values are achieved. Recently completed studies provide the evidence to support this approach. Hypertension in patients with lower limb ischemia increases the already high cardiovascular risk in these patients. Blood pressure reduction as such is more important than a specific antihypertensive.
