The key to resolving any chronic health condition is to discover the root causes and then supply the body with the needed raw materials to correct any deficiencies or to bring the body back into balance. Therefore, you will need to become somewhat of a detective, patiently investigating each known
Tag: atrial fibrillation
Atrial fibrillation is an arrhythmia in the top chambers of the heart (atria) causing uncoordinated muscular contractions that weaken the heart’s ability to pump. It is characterized by rapid and irregular beating.
Often it starts as brief periods of abnormal beating which become longer and possibly constant over time. Most episodes have no symptoms. Occasionally there may be heart palpitations, fainting, shortness of breath, or chest pain. The disease increases the risk of heart failure, dementia, and stroke.
Although atrial fibrillation itself usually isn’t life-threatening, it is a serious medical condition that sometimes requires emergency treatment.
Hypertension and valvular heart disease are the most common alterable risk factors for AF. Other heart-related risk factors include heart failure, coronary artery disease, cardiomyopathy, and congenital heart disease. In the developing world, valvular heart disease often occurs as a result of rheumatic fever. Lung-related risk factors include COPD, obesity, and sleep apnea.
Other factors include excess alcohol intake, diabetes mellitus, and thyrotoxicosis. However, half of cases are not associated with one of these risks.
A diagnosis is made by feeling the pulse and may be confirmed using an electrocardiogram (ECG). The typical ECG shows no P waves and an irregular ventricular rate.
AF is often treated with medications to slow the heart rate to a near normal range (known as rate control) or to convert the rhythm to normal sinus rhythm (known as rhythm control). Electrical cardioversion can also be used to convert AF to a normal sinus rhythm and is often used emergently if the person is unstable. Ablation may prevent recurrence in some people. Depending on the risk of stroke, either aspirin or anti-clotting medications such as warfarin or a novel oral anticoagulant may be recommended. While these medications reduce this risk, they increase rates of major bleeding.
High cholesterol can have wide-ranging effects—both direct and indirect—on your heart and several other organs served by your vascular system. As cholesterol builds in the arteries of your heart, brain, and throughout your body, it usually does so silently. In some cases, the first signs of atherosclerosis may be a
About 8 percent of Americans take fish oil supplements, likely due to research suggesting they may help protect heart health. However, two trials published in the New England Journal of Medicine (NEJM), Nov. 10, 2018, show mixed results on the benefits of fish oil. If you’re taking it, should you
Before you reach for a Monster energy drink, consider this: Are energy drinks bad for you? A growing number of studies are finding that products like Monster, Red Bull, and 5-Hour Energy can result in a variety of health dangers without offering any unique benefits.
The extreme acidity and high caffeine
It’s vitally important to treat atrial fibrillation (AFib) to reduce the risk of stroke, heart failure, and death, but we now know that this common cardiac condition doesn’t affect only the heart. The Atherosclerosis Risk in Communities Neurocognitive Study found that AFib is also associated with a heightened risk of
When you bite into a forkful of dark, leafy greens like kale or spinach, you ingest lots of vitamin K. That’s good, because K is crucial for your health, especially for blood clotting and bone strength.
But vitamin K is sometimes misunderstood. Because of its clotting properties, it can interfere with
Can adding electrocardiography (ECG) to standard screening help health-care providers better protect healthy patients from developing cardiovascular disease (CVD)? Probably not, says the U.S. Preventive Services Task Force (USPSTF). In fact, it may actually put patients at risk.
Current Screening Standards. Standard risk assessment for cardiovascular disease often begins with a tool such as
Osteoporosis Drugs Work Best When Taken Consistently
Women with osteoporosis who consistently take medication that prevents further bone loss and/or strengthens bone have a lower risk for fractures than those who take the medication inconsistently, according to a study published in the November 2018 issue of Osteoporosis International. The researchers analyzed Medicare
Acrucial weapon in the fight against arthritis is medication that, in some cases, slows disease progression as well as easing pain, maximizing joint function, and improving quality of life. There is no one-size-fits-all solution—trial and error may be required to find the drug (or drug combination) that works for you.
You get regular exercise, eat right, and don’t smoke, and you have no symptoms that suggest heart trouble, so you assume that your risk for a heart attack, stroke, or other cardiovascular event is low. However, regardless of how healthy your lifestyle is, you need to be aware of the
