source: Natalie Cole
text: Natalie Cole Natalie Maria Cole (February 6, 1950 – December 31, 2015) was an American singer, voice actress, songwriter, and actress. The daughter of Nat King Cole, she rose to musical success in the mid-1970s as an R&B artist with the hits "This Will Be", "Inseparable" (1975), and "Our Love" (1977). After a period of failing sales and performances due to a heavy drug addiction, Cole re-emerged as a pop artist with the 1987 album "Everlasting" and her cover of Bruce Springsteen's "Pink Cadillac". In the 1990s, she re-recorded standards by her father, resulting in her biggest success, "Unforgettable... with Love", which sold over seven million copies and also won Cole seven Grammy Awards. She sold over 30 million records worldwide. She is best known for the role of herself in "Yakety Yak, Take it Back", and "Trash Talk", and the singing voice of Sawyer Cat in the "Cats Don't Dance" franchise. On December 31, 2015, Cole died at the age of 65 at Cedars-Sinai Medical Center in Los Angeles, California, due to congestive heart failure.

text: Christmas in Vienna VI Christmas in Vienna VI (also known as Christmastime in Vienna) is the seventh album in a series of Christmas concerts recorded in Vienna with Spanish tenor Plácido Domingo. The concert that the recording comes from was the seventh Christmas in Vienna show that Domingo held since 1992, and the sixth concert recording to be released by Sony Classical. (The Erato label released the fourth Christmas in Vienna concert from 1995 that Domingo held with José Carreras and Natalie Cole.) Recorded in December 1998, it also includes the French singer Patricia Kaas and the Mexican singer Alejandro Fernández with the Vienna Symphony Orchestra directed by Steven Mercurio. The album was released in September 1999.

text: Congestive hepatopathy Congestive hepatopathy, also known as nutmeg liver and chronic passive congestion of the liver, is liver dysfunction due to venous congestion, usually due to congestive heart failure. The gross pathological appearance of a liver affected by chronic passive congestion is "speckled" like a grated nutmeg kernel; the dark spots represent the dilated and congested hepatic venules and small hepatic veins. The paler areas are unaffected surrounding liver tissue. When severe and longstanding, hepatic congestion can lead to fibrosis; if congestion is due to right heart failure, it is called cardiac cirrhosis.

Ruffolo (born April, 1950, in Yonkers, N.Y.) was president of research and development for Wyeth Pharmaceuticals, and corporate Senior Vice President of Wyeth from 2001 to 2008. During his career in the pharmaceutical industry, Ruffolo played a significant role in the discovery and/or development of a number of marketed products, including dobutamine (Dobutrex) for the acute management of congestive heart failure, and eprosartan (Teveten) for hypertension. He holds the patent for the discovery of use of carvedilol (Coreg) for the treatment of congestive heart failure, and he led the research team that discovered ropinerole (Requip) for Parkinson's Disease.

source: Trepopnea
text: Trepopnea Trepopnea /tre·pop·nea/ (tre″pop-ne´ah) is dyspnea (shortness of breath) that is sensed while lying on one side but not on the other (lateral recumbent position). It results from disease of one lung, one major bronchus, or chronic congestive heart failure. Patients with trepopnea from lung disease prefer to lie on the opposite side of the diseased lung, as the gravitation increases perfusion of the lower lung. Increased perfusion in diseased lung would increase shunting and hypoxemia, resulting in worsening shortness of breath. To maximize function of the healthier lung, the patient is best to lie on the side of the healthier lung, so that it receives adequate perfusion. Patients with chronic heart failure prefer to lie mostly on the right side, to enable a better blood return, whereby cardiac output is augmented.

source: Heart failure with preserved ejection fraction
text: Heart failure with preserved ejection fraction Heart failure with preserved ejection fraction (HFpEF) is a form of congestive heart failure wherein the amount of blood pumped from the heart's left ventricle with each beat (ejection fraction) is greater than 50%. Approximately half of people with heart failure have HFpEF, while the remainder display a reduction in ejection fraction, or heart failure with reduced ejection fraction (HFrEF).

source: Heart failure
text: Heart failure Heart failure (HF), often referred to as congestive heart failure (CHF), occurs when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs. Signs and symptoms commonly include shortness of breath, excessive tiredness, and leg swelling. The shortness of breath is usually worse with exercise, while lying down, and may wake the person at night. A limited ability to exercise is also a common feature. Chest pain, including angina, does not typically occur due to heart failure.

source: Terry's nails
text: Terry's nails Terry's nails is a physical condition in which a person's fingernails or toenails appear white with a characteristic "ground glass" appearance without any lunula. The condition is thought to be due to a decrease in vascularity and an increase in connective tissue within the nail bed. It frequently occurs in the setting of liver failure, cirrhosis, diabetes mellitus, congestive heart failure, hyperthyroidism, or malnutrition. Eighty percent of patients with severe liver disease have Terry's nails, but they are also found in patients with kidney failure, in patients with congestive heart failure and are described as a brown arc near the ends of the nails. The recognition of characteristic nail patterns, such as Terry’s nails, may be a helpful herald for early diagnosis of systemic diseases.

source: Metolazone
text: Metolazone Metolazone is a thiazide-like diuretic marketed under the brand names Zytanix from Zydus Cadila, Zaroxolyn, and Mykrox. It is primarily used to treat congestive heart failure and high blood pressure. Metolazone indirectly decreases the amount of water reabsorbed into the bloodstream by the kidney, so that blood volume decreases and urine volume increases. This lowers blood pressure and prevents excess fluid accumulation in heart failure. Metolazone is sometimes used together with loop diuretics such as furosemide or bumetanide, but these highly effective combinations can lead to dehydration and electrolyte abnormalities.

source: Cardiac asthma
text: Cardiac asthma Cardiac asthma is a medical diagnosis of wheezing, coughing or shortness of breath due to congestive heart failure. It is known as cardiac asthma because the symptoms mimic ordinary asthma (bronchial asthma). One study found that patients with cardiac asthma represented one third of congestive heart failure in elderly patients.
