Angiotensin-converting-enzyme inhibitors are a class of medication used primarily for the treatment of high blood pressure and heart failure. They work by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart.
Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome, a group of signs and symptoms caused by an impairment of the heart's blood pumping function. Symptoms typically include shortness of breath, excessive fatigue, and leg swelling. The shortness of breath may occur with exertion or while lying down, and may wake people up during the night. Chest pain, including angina, is not usually caused by heart failure, but may occur if the heart failure was caused by a heart attack. The severity of the heart failure is measured by the severity of symptoms during exercise. Other conditions that may have symptoms similar to heart failure include obesity, kidney failure, liver disease, anemia, and thyroid disease.
Digoxin, sold under the brand name Lanoxin among others, is a medication used to treat various heart conditions. Most frequently it is used for atrial fibrillation, atrial flutter, and heart failure. Digoxin is one of the oldest medications used in the field of cardiology. It works by increasing myocardial contractility, increasing stroke volume and blood pressure, reducing heart rate, and somewhat extending the time frame of the contraction. Digoxin is taken by mouth or by injection into a vein. Digoxin has a half life of approximately 36 hours given at average doses in patients with normal renal function. It is excreted mostly unchanged in the urine.
Rosiglitazone is an antidiabetic drug in the thiazolidinedione class. It works as an insulin sensitizer, by binding to the PPAR in fat cells and making the cells more responsive to insulin. It is marketed by the pharmaceutical company GlaxoSmithKline (GSK) as a stand-alone drug or for use in combination with metformin or with glimepiride. First released in 1999, annual sales peaked at approximately $2.5-billion in 2006; however, following a meta-analysis in 2007 that linked the drug's use to an increased risk of heart attack, sales plummeted to just $9.5-million in 2012. The drug's patent expired in 2012.
Antihypertensives are a class of drugs that are used to treat hypertension. Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Evidence suggests that reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%, and can reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease. There are many classes of antihypertensives, which lower blood pressure by different means. Among the most important and most widely used medications are thiazide diuretics, calcium channel blockers, ACE inhibitors, angiotensin II receptor antagonists (ARBs), and beta blockers.
Ramipril, sold under the brand name Altace among others, is an ACE inhibitor type medication used to treat high blood pressure, heart failure, and diabetic kidney disease. It can also be used as a preventative medication in patients over 55 years old to reduce the risk of having a heart attack, stroke or cardiovascular death in patients shown to be at high risk, such as some diabetics and patients with vascular disease. It is a reasonable initial treatment for high blood pressure. It is taken by mouth.
Candesartan is an angiotensin receptor blocker used mainly for the treatment of high blood pressure and congestive heart failure. Candesartan has a very low maintenance dose. The metabolism for the drug is unique as it is a cascading prodrug. Candesartan has good bioavailibility and is more potent among the AT-1 receptor antagonists.
A ventricular assist device (VAD) is an electromechanical device for assisting cardiac circulation, which is used either to partially or to completely replace the function of a failing heart. The function of a VAD differs from that of an artificial cardiac pacemaker in that a VAD pumps blood, whereas a pacemaker delivers electrical impulses to the heart muscle. Some VADs are for short-term use, typically for patients recovering from myocardial infarction and for patients recovering from cardiac surgery; some are for long-term use, typically for patients with advanced heart failure.
Perindopril is a medication used to treat high blood pressure, heart failure, or stable coronary artery disease.
Ivabradine, sold under the brand name Procoralan among others, is a medication, which is a funny current (If) inhibitor, used for the symptomatic management of heart-related chest pain and heart failure. Patients who qualify for use of Ivabradine for coronary heart failure are patients who have symptomatic heart failure, with reduced ejection volume, and heart rate at least 70 bpm, and the condition not able to be fully managed by beta blockers.
Levosimendan (INN) is a calcium sensitizer used in the management of acutely decompensated congestive heart failure. It is marketed under the trade name Simdax. Overall the drug has a two fold mechanism of action. It leads to greater ionotrophy by increasing the calcium sensitivity as it binds to Troponin and this results in a greater positive iontrophic force. Secondly, the drug is able to open ATP sensitive potassium channels in vascular smooth muscle cells, and the vascular dilatory effects of the drug lead to a decreased pre-load and afterload, putting less work on the heart. This drug is in the process of review by the FDA but has not been approved yet.
Amrinone, also known as inamrinone, and sold as Inocor, is a pyridine phosphodiesterase 3 inhibitor. It is a drug that may improve the prognosis in patients with congestive heart failure. Amrinone has been shown to increase the contractions initiated in the heart by high-gain calcium induced calcium release (CICR). The positive inotropic effect of amrinone is mediated by the selective enhancement of high-gain CICR, which contributes to the contraction of myocytes by phosphorylation through cAMP dependent protein kinase A (PKA) and Ca2+ calmodulin kinase pathways.
Celacade was a non-drug, device-based treatment also known as Immune Modulation Therapy (IMT), developed by the Canadian-based biotherapeutics company Vasogen, Inc. for chronic heart failure and peripheral artery disease. Blood was piped through the device, where it was exposed to heat, ultraviolet light, and ozone, in the hope that this oxidative stress would trigger an anti-inflammatory immunomodulation response.
Dapagliflozin, sold under the brand names Farxiga (US) and Forxiga (EU) among others, is a medication used to treat type 2 diabetes. It is also used to treat adults with heart failure and chronic kidney disease.
The ST2 cardiac biomarker is a protein biomarker of cardiac stress encoded by the IL1RL1 gene. ST2 signals the presence and severity of adverse cardiac remodeling and tissue fibrosis, which occurs in response to myocardial infarction, acute coronary syndrome, or worsening heart failure.
Management of heart failure requires a multimodal approach. It involves a combination of lifestyle modifications, medications, and possibly the use of devices or surgery.
Philip Alexander Poole-Wilson FRCP, FESC, FACC, FMedSci was a British academic cardiologist of international reputation who had particular interest in the management of heart failure. His research helped to identify the cellular mechanisms behind heart failure and was also important in improving treatment for patients. He was instrumental in raising the profile of heart failure as a major public health problem.
Sacubitril/valsartan, sold under the brand name Entresto, is a fixed-dose combination medication for use in heart failure. It consists of the neprilysin inhibitor sacubitril and the angiotensin receptor blocker valsartan. The combination is sometimes described as an "angiotensin receptor-neprilysin inhibitor" (ARNi). It is recommended for use as a replacement for an ACE inhibitor or an angiotensin receptor blocker in people with heart failure with reduced ejection fraction.
The Q-Symbio study was an international multi-center clinical trial that was reported in the Journal of the American College of Cardiology: Heart Failure in September 2014.
Milton Packer is an American cardiologist who is known for his clinical research concerning heart failure.
