diastolický

Diastolický is an adjective used in Czech medical terminology to describe things related to diastole, the phase of the cardiac cycle when the heart chambers relax and fill with blood. The term is commonly used in connection with the heart’s relaxation phase, diastolic function, and diastolic blood pressure.

During diastole the ventricles relax and expand, the heart valves between chambers are open, and passive filling of the ventricles occurs. Late diastole may involve atrial contraction that completes ventricular filling. This phase contrasts with systole, the period of heart contraction and blood ejection.

Diastolická funkce (diastolic function) refers to the heart’s ability to relax and fill normally. Impairment of this function, known as diastolic dysfunction, can result from conditions such as long-standing hypertension, aging, left ventricular hypertrophy, ischemia, or cardiomyopathy. Severe diastolic dysfunction may lead to heart failure with preserved ejection fraction (HFpEF), a form of heart failure where the heart’s pumping capacity remains relatively intact but filling is restricted.

Diastolický krevní tlak (diastolic blood pressure) is the lower value of a blood pressure reading, representing the pressure in arteries when the heart is in diastole. Blood pressure management, control of risk factors (e.g., hypertension, obesity, diabetes), and treatment of underlying cardiac conditions are central to addressing diastolic problems. Diagnostics commonly include echocardiography, which assesses diastolic function through parameters such as filling patterns and pressure estimates.
