Angina : Definition: Angina is chest pain or discomfort that occurs when an area of the heart is deprived of oxygen. It is typically described as a crushing or squeezing sensation in the chest and may radiate to the jaw, shoulders, arm or back. It is usually a symptom of underlying heart disease, such as coronary artery disease. Angina can be classified into two i.e Stable Angina and Unstable Angina
Stable Angina - Usually results from atherosclerotic plaques in the coronary arteries. Acute attacks of stable angina should be managed with (1) Nitrates - Glyceryl trinitrate, Isosorbide dinitrate
(2) Antiplatelet drugs - Aspirin
(3) Calcium-channel blockers - Verapamil , Diltiazem,Nifedipine, nicardipine, amlodipine, and felodipine
(4) Other antianginal drugs - Nicorandil and Ivabradine
Unstable Angina - usually due to plaque rupture and may occur either in patients with a history of stable angina or in those with previously silent coronary artery disease. Unstable angina (UA) (also "c
Hypertension : Hypertension, also referred to as high blood pressure, is a condition in which the arteries have persistently elevated blood pressure. Every time the human heart beats, it pumps blood to the whole body through the arteries.
Blood pressure is the force of blood pushing up against the blood vessel walls. The higher the pressure the harder the heart has to pump. Hypertension can lead to damaged organs, as well as several illnesses, such as renal failure (kidney failure), aneurysm, heart failure, stroke, or heart attack.
The normal level for blood pressure is below 120/80, where 120 represents the systolic measurement (peak pressure in the arteries) and 80 represents the diastolic measurement (minimum pressure in the arteries). Blood pressure between 120/80 and 139/89 is called pre hypertension (to denote increased risk of hypertension), and a blood pressure of 140/90 or above is considered hypertension.
Hypertension may be classified as essential or secondary. Essential hypertension is the term for high blood pressure with unknown cause. It accounts for about 95% of cases. Secondary hypertension is the term for high blood pressure with a known direct cause, such as kidney disease, tumors, or birth control pills.
Migraine : Migraine is a chronic neurological disorder characterized by recurrent moderate to severe headaches often in association with a number of autonomic nervous system symptoms. Migraine is a severe, painful headache that is often preceded or accompanied by sensory warning signs such as flashes of light, blind spots, tingling in the arms and legs, nausea, vomiting, and increased sensitivity to light and sound.
Medication
Preventive migraine medications are considered effective if they reduce the frequency or severity of the migraine attacks by at least 50%. Guidelines are fairly consistent in rating topiramate, divalproex/sodium valproate, propranolol, and metoprolol as having the highest level of evidence for first-line use. Recommendations regarding effectiveness varied however for gabapentin. Timolol is also effective for migraine prevention and in reducing migraine attack frequency and severity, while frovatriptan is effective for prevention of menstrual migraine.
Amitriptyline and venlafaxine are probably also effective. Angiotensin inhibition by either an angiotensin-converting enzyme inhibitor orangiotensin II receptor antagonist may reduce attacks. Botox has been found to be useful in those with chronic migraines but not those with episodic ones.
