Guidelines on the choice of agents and how best to step up treatment for various subgroups in hypertension (high blood pressure) have changed over time and differ between countries. A Comparison of International Guidelines on Goal Blood Pressure and Initial Therapy for Adults With Hypertension (adapted from JNC 8 guidelines [ 1 ] )
Cardiotonic agents, also known as cardiac inotropes or stimulants, have a positive impact on the myocardium (muscular layer of the heart) by enhancing its contractility. . Unlike general inotropes, these agents exhibit a higher level of specificity as they selectively target the myocar
An antihypotensive, also known as vasopressor, is an agent that raises blood pressure by constricting blood vessels, thereby increasing systemic vascular resistance. This is different from inotropes which increase the force of cardiac contraction. Some substances do both (e.g. dopamine, dobutamine).
Negative inotropic agents decrease myocardial contractility and are used to decrease cardiac workload in conditions such as angina. While negative inotropism may precipitate or exacerbate heart failure in the short term, certain beta blockers (e.g. carvedilol , bisoprolol and metoprolol ) have been believed to reduce long-term morbidity and ...
The acronym "SMART" stands for Standards-based, Machine-readable, Adaptive, Requirements-based, and Testable, which outlines the structured approach used to translate traditional health guidelines into formats suitable for digital health systems.: [1] The objective of SMART guidelines is to promote adaptation of WHO guidelines while preserving ...
The Surviving Sepsis Campaign guidelines recommend the very early management of the sepsis focusing on the hour-1 bundle. This includes use of Vasopressin 0.03 units/minute as add-on to norepinephrine (NE) with intent of either raising the mean arterial pressure or decreasing the norepinephrine dosage (i.e. de-catecholaminization). [13]
Medications used include: diuretic agents, vasodilator agents, positive inotropes, ACE inhibitors, beta blockers, and aldosterone antagonists (e.g., spironolactone). Some medications which increase heart function, such as the positive inotrope milrinone, lead to increased death, and are contraindicated. [9] [10]
A cardiac stimulant is a drug which acts as a stimulant of the heart – e.g., via positive chronotropic action (increased heart rate) and/or inotropic action (increased myocardial contractility). They increase cardiac output (the amount of blood pumped by the heart over time).
