Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water.Solutions of HF are colorless, acidic and highly corrosive.A common concentration is 49% (48-52%) but there are also stronger solutions (e.g. 70%) and pure HF has a boiling point near room temperature.
Overview. Heart failure happens when the heart cannot pump enough blood and oxygen to support other organs in your body. Heart failure is a serious condition, but it does not mean that the heart has stopped beating.
Heart failure (HF) remains a prevailing cause of cardiovascular morbidity and mortality globally despite advancements in therapies and preventive measures. The Centers for Disease Control and Prevention (CDC) estimates that 6.7 million individuals aged 20 or older in the United States are affected by HF. It is anticipated that the prevalence of HF will increase to 8.5 million Americans by 2030.
What is HF? Heart Failure (HF) is a very common problem in the United States. 1 in 5 Americans will develop heart failure in their lifetime. 1 About 915,000 new patients are diagnosed with heart failure each year. 1 It is the leading cause for adults over the age of 65 to be admitted to the hospital. The most common cause for a visit to the emergency room for someone with HF is fluid retention.
Learn about the four stages of congestive heart failure (HF), a condition that occurs when the heart cannot pump blood efficiently. Find out the causes, risk factors, diagnosis, and prevention of HF and how it affects the quality of life.
Learn about the new consensus document that standardizes the definition and classification of HF based on symptoms, signs, LVEF and natriuretic peptides. Find out how the universal definition and classification can improve diagnosis, prognosis and treatment of HF.
Heart failure (HF) is a syndrome of ventricular dysfunction. Left ventricular (LV) failure causes shortness of breath and fatigue, and right ventricular (RV) failure causes peripheral and abdominal fluid accumulation; the ventricles can be involved together or separately.
The fluoride ions in HF readily bind calcium and magnesium, reducing their levels in the blood, resulting in hypotension and cardiac effects. 1 Deaths have been reported from concentrated acid burns (involving ≥ 50% HF solutions) to as little as 2.5% of body surface area, which is equivalent to approximately one hand and forearm. 2 In lower ...
