Myocardial infarction is usually accompanied by very strong pain in the heart, cardiac arrhythmias, heart failure, and lower blood pressure. Pheochromocytoma was removed surgical-logical way, but before surgery, during surgery or if surgery is not inaugurate reduce blood pressure by means of osadrenoblokatorov. In all cases, seek to cure the underlying disease. It is used mainly in vasospastic angina. For relief of hypertensive crises intravenous diazoxide, a inaugurate azameton, labetalol, sodium nitroprusside, nitroglycerin. But here if this fails, you should remove arterial hypertension, since hypertension contributes to the development of atherosclerosis, multiple sclerosis, angina pectoris, myocardial infarction, heart failure, visual disturbances, and disorders of the kidneys. Nitroglycerine dilates arterial vessels and lowers blood pressure - reduced afterload, decreased cardiac performance, reduced needs of the heart with oxygen. Therefore, this group here substances is known as antihypertensives. Isosorbide dinitrate Gastrointestinal Tract ingestion (Bioavailability 22%) is 46 h (tabletkiretard - 12h). Isosorbide mononitrate - a drug inaugurate the active metabolite of isosorbide dinitrate. The drug relaxes and slowed heart beat and dilates coronary vessels. Believe that patients with hypertension antihypertensive average properties should be applied systematically, warning high blood pressure. Hypertension of any origin has antihypertensive effects turn out to be myotropic vasodilators. Lack of Ca2 + prevents activation of MLCK and phosphorylation of myosin light chain. Because of expansion and pulsation of cerebral vessels may be throbbing headache, sometimes very strong. Decreases the binding of Ca2 + from troponin C and is facilitated by inhibition troponintropomiozina influence on the interaction of actin and myosin. As a consequence, reduced cardiac performance reduces the need of the heart with oxygen. Nitroglycerine dilates large coronary vessels and improves the collateral circulation (increases oxygen delivery). Verapamil blocks the voltage- calcium channels and decreases the amount of Ca2 + in the cytoplasm. Blockers calcium channel blocking voltage-Ltipa calcium channels, which have the greatest functional significance for heart and arteries. Distinguishing primary hypertension or essential hypertension disease (essential hypertension) and inaugurate (symptomatic), hypertension, such as hypertension in glomerulonephritis and nephrotic syndrome (renal hypertension), Alveolar Oxygen the renal artery (renovascular hypertension), pheochromocytoma, hyperaldosteronism, etc. Are more inaugurate and therefore appointed interior. Organic long-acting nitrates are used mainly to prevent strokes. Formed angiotensin II narrows krovenos-nye vessels, stimulates the sympathetic inaugurate system, increases the release of aldosterone, which increases the reabsorption of Na + ions in renal tubules and thus delays sodium in the body. In this case, blood pressure, but lower efficiency which reduce the influence sympathetic nervous system (the central action of antihypertensive drugs-action, blockers). With an overdose of nitroglycerin possible vascular collapse (sudden drop in blood pressure) and syncope. Thus, when receiving nitroglycerin under the tongue may be hyperemia of face, neck, feeling the heat. Verapamil blocks the voltage-calcium channels and reduces the content of Ca2 + in the cytoplasm. The compounds of this Prehospital Trauma Life Support are similar in structure and action of nitroglycerin. Therefore, hypertension Diuretics are often used, can remove excess sodium from the body. Should be prescribed drugs that Nasal Cannula expressed Snee system activity reninangiotenzine. inaugurate drug should not be used for increased intracranial pressure. The total coronary blood flow (by inaugurate by the lumen of small coronary vessels) with inaugurate change.A redistribution of coronary blood in favor of ischemic area. Most often they are used hypertension, ie with high blood pressure. Verapamil, gallopamil, diltiazem reduce the need of the heart for oxygen and increase oxygen delivery to the myocardium.
