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).
There are several known causes of adrenergic storms; in the United States, cocaine overdose is the leading cause. [16] Any stimulant drug has the capacity to cause this syndrome if taken in sufficient doses, but even non-psychotropic drugs can very rarely provoke a reaction.
[70] [71] Stimulants such as amphetamine and methylphenidate can improve performance on difficult and boring tasks, [70] [c] [71] [72] and are used by some students as a study and test-taking aid. [ 43 ] [ 73 ] Based upon studies of self-reported illicit stimulant use, performance-enhancing use rather than use as a recreational drug , is the ...
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
Research has shown higher resting heart rate to be associated with higher body weight, higher blood pressure, and lower physical fitness, the AHA notes. Other studies have demonstrated a link ...
A 2018 Cochrane review found that, in rare cases, nicotine replacement therapy can cause non-ischemic chest pain (i.e., chest pain that is unrelated to a heart attack) and heart palpitations, but does not increase the incidence of serious cardiac adverse events (i.e., myocardial infarction, stroke, and cardiac death) relative to controls.

[48] [71] Amphetamine and other ADHD stimulants also improve task saliency (motivation to perform a task) and increase arousal (wakefulness), in turn promoting goal-directed behavior. [48] [72] [73] Stimulants such as amphetamine can improve performance on difficult and boring tasks and are used by some students as a study and test-taking aid.
A stimulant is an overarching term that covers many drugs including those that increase the activity of the central nervous system and the body, [5] drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects. [6] Sympathomimetic effects are those effects that mimic or copy the actions of the sympathetic nervous ...
