Heart failure characteristically involves increased catecholamine activity on the heart, which is responsible for several deleterious effects, including increased oxygen demand, propagation of inflammatory mediators, and abnormal cardiac tissue remodeling, all of which decrease the efficiency of cardiac contraction and contribute to the low ...
More severe hyponatremia (levels less than 120 mEq/L), particularly if it develops rapidly (defined as occurring over less than 48 hours), can cause confusion, seizures and even lead to death ...
Sodium channel blockers are used in the treatment of cardiac arrhythmia. They are classified as "Type I" in the Vaughan Williams classification. Class I antiarrhythmic agents interfere with the (Na +) channel. Class I agents are grouped by their effect on the Na + channel, and by their effect on cardiac action potentials. Class I agents are ...
High volume hyponatremia can occur from heart failure, liver failure, and kidney failure. [4] Conditions that can lead to falsely low sodium measurements include high blood protein levels such as in multiple myeloma, high blood fat levels, and high blood sugar. [5] [6] Treatment is based on the underlying cause. [4]
Cardiovascular agents are drugs used to treat diseases associated with the heart or blood vessels. These medications are available for purchase only with a physician’s prescription . They include, but are not limited to, drugs that target hypertension ( antihypertensives ), hyperlipidemia ( antihyperlipidemics ) and blood clotting (blood ...
The causes of SIADH are commonly grouped into categories including: central nervous system diseases that directly stimulate the hypothalamus to release ADH, various cancers that synthesize and secrete ectopic ADH, various lung diseases, numerous drugs that may stimulate the release of ADH, enhance ADH effects, act as ADH analogues in the body ...
V 2 R antagonists have become a mainstay of treatment for euvolemic (i.e., SIADH, postoperative hyponatremia) and hypervolemic hyponatremia (i.e., CHF and cirrhosis). [9] V 2 RAs predictably cause aquaresis leading to increased [Na +] in majority of patients with hyponatremia due to SIADH, CHF, and cirrhosis. The optimum use of VRAs has not yet ...
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]
