Arterial hypertension is a condition that causes high blood pressure. For diagnosis of arterial hypertension high values of blood pressure (≥ 140/90) are needed in two succesive measures. Prevalence of hyypertension, in Croatia, is 35.2% for men and 39.7% for women. Hypertension is divided into essential and secondary hypertension. Symptoms are not present in early stages and is discovered by accident measuring blood pressure when visiting general practice. Heart failure is a complex clinical syndrome that results with inability of ventricular filling and lowered ejection fraction. NYHA classification is used in assessment of the heart failure stage. Heart failure is divided into acute and chronic. Chronic heart failure is divided into heart failure with reduced ejection fraction(HFrEF) and heart failure with preserved ejection fraction (HFpEF). When examining the patient with arterial hypertension and heart failure man signs of these diseases are present, including high values of blood pressure, cough, usement of accessory respiratory muscles, ascites, peripheralPregledom bolesnika nalazimo razne znakove bolesti. Neki od znakova su povišene vrijednosti krvnog tlaka, kašalj, upotreba pomoćne respiratorne oedema etc. Diagnosis is determined by anamnesis, clinical picture and using clinical tests. Goal of the treatment is reducing cardiovascular risk and expanding life span with as few compliations and hospitalizations as possible. Treatment is based on changing lifestyle and drug treatment. Combination of ACEI, β – blockers and antimineralocorticoid drug is the first line of drug treatment of patients with hypertension and HFrEF. Patients that have hypertension with HFpEF ACEI are the first line of treatment. Presence of symptoms caused by congestion demands treatment with diuretic. Last line of treatment is heart tranplantation.
