The 2021 ADAPTABLE study also showed no significant difference in cardiovascular events or major bleeding between 81 mg and 325 mg doses of aspirin in patients (both men and women) with established cardiovascular disease.Low-dose aspirin use was also associated with a trend toward lower risk of cardiovascular events, and lower aspirin doses (75 or 81 mg/day) may optimize efficacy and safety for people requiring aspirin for long-term prevention.In children with Kawasaki disease, aspirin is taken at dosages based on body weight, initially four times a day for up to two weeks and then at a lower dose once daily for a further six to eight weeks. Adverse effects
In October 2020, the US Food and Drug Administration (FDA) required the drug label to be updated for all nonsteroidal anti-inflammatory medications to describe the risk of kidney problems in unborn babies that result in low amniotic fluid. They recommend avoiding NSAIDs in pregnant women at 20 weeks or later in pregnancy. One exception to the recommendation is the use of low-dose 81 mg aspirin at any point in pregnancy under the direction of a health care professional. Contraindications
Aspirin should not be taken by people who are allergic to ibuprofen or naproxen, or who have salicylate intolerance or a more generalized drug intolerance to NSAIDs, and caution should be exercised in those with asthma or NSAID-precipitated bronchospasm. Owing to its effect on the stomach lining, manufacturers recommend people with peptic ulcers, mild diabetes, or gastritis seek medical advice before using aspirin.
Cardiac amyloidosis is a subcategory of amyloidosis where there is depositing of the protein amyloid in the cardiac muscle and surrounding tissues. Amyloid, a misfolded and insoluble protein, can become a deposit in the hearts atria, valves, or ventricles. These deposits can cause thickening of different sections of the heart, leading to decreased cardiac function. The overall decrease in cardiac function leads to a plethora of symptoms. This multisystem disease was often misdiagnosed, with diagnosis previously occurring after death during autopsy. However, recent advancements of technologies have increased the diagnosis of the disease. Cardiac amyloidosis has multiple sub-types including light chain, familial, and senile. One of the most studied types is light chain cardiac amyloidosis. Prognosis depends on the extent of the deposits in the body and the type of amyloidosis. New treatment methods are actively being researched in regards to the treatment of heart failure and specific cardiac amyloidosis problems. Types
The multiple subtypes of cardiac amyloidosis have varying epidemiological, diagnostic, and prognostic characteristics. Light chain (AL-CM)
This relatively rare form of cardiac amyloidosis occurs in an estimated six to ten cases per 1,000,000 people. This sub- type usually affects males over the age of 60 and is rapidly progressive. Pathogenesis of this form is due to the aggregation of immunoglobulin lambda light chains. These chains are created by an abnormal expansion of plasma cells. Over time, these light chains deposit into the interstitial tissue within the myocardium.
