2. Cardiotonic agent - Wikipedia

   en.wikipedia.org/wiki/Cardiotonic_agent

   Calcium is a vital element for regulating the contraction and relaxation of the heart muscle. [6] Calcium sensitizers are medications that increase the responsiveness of heart muscle cells to calcium, enabling more forceful contractions while conserving energy. [49] Contraction of the heart muscle relies on electrical signals that trigger the ...

3. Coronary CT calcium scan - Wikipedia

   en.wikipedia.org/wiki/Coronary_CT_calcium_scan

   A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. [1] These plaques are the cause of most heart ...

4. Cardiac action potential - Wikipedia

   en.wikipedia.org/wiki/Cardiac_action_potential

   These calcium ions bind to and open more calcium channels (called ryanodine receptors) located on the sarcoplasmic reticulum within the cell, allowing the flow of calcium out of the SR. These calcium ions are responsible for the contraction of the heart. Calcium also activates chloride channels called I to2, which allow Cl − to enter the cell ...

5. Myocardial contractility - Wikipedia

   en.wikipedia.org/wiki/Myocardial_contractility

   When it's phosphorylated by PKA, levels of calcium stored in the sarcoplasmic reticulum are increased, allowing a higher rate of calcium being released at the next contraction. However, the increased rate of calcium sequestration also leads to an increase in lusitropy. Sensitizing troponin-C to the effects of calcium.

6. Bowditch effect - Wikipedia

   en.wikipedia.org/wiki/Bowditch_effect

   Positive Bowditch effect causes an increase in cardiac output due to the increased force of contraction of heart muscles. [7]This phenomenon is usually absent or even reversed (negative Bowditch effect) in heart failure and other diseases of heart, such as cardiomyopathy and coronary artery disease.

8. Calcium channel blocker toxicity - Wikipedia

   en.wikipedia.org/wiki/Calcium_channel_blocker...

   More than 10,000 cases of potential calcium channel blocker toxicity occurred in the United States in 2010. [2] When death occurs in medicine overdose, heart medications are the cause more than 10% of time. [2] The three most common types of heart medications that result in this outcome are calcium channel blockers along with beta blockers and ...

9. Cardiovascular agents - Wikipedia

   en.wikipedia.org/wiki/Cardiovascular_agents

   Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD.
