Angina is chest pain due to inadequate blood supply to the heart. Angina symptoms may include chest tightness, burning, squeezing, and aching. Coronary artery disease is the main cause of angina but there are other causes. Angina is diagnosed by taking the patient's medical history and performing tests such as an electrocardiogram (EKG), blood test, stress test, echocardiogram, cardiac CT scan, and heart catheterization. Treatment of angina usually includes lifestyle modification, medication, and sometimes, surgery. The risk of angina can be reduced by following a heart healthy lifestyle.

An arrhythmia is an abnormal heart rhythm. With an arrhythmia, the heartbeats may be irregular or too slow (bradycardia), to rapid (tachycardia), or too early. When a single heartbeat occurs earlier than normal, it is called a prmature contraction.

Heart attack happens when a blood clot completely obstructs a coronary artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical instability of the heart.

Heart disease (coronary artery disease) occurs when plaque builds up in the coronary arteries, the vessels that supply blood to the heart. Heart disease can lead to heart attack. Risk factors for heart disease include:

• Smoking
• High blood pressure
• High cholesterol
• Diabetes
• Family history
• Obesity

Angina, shortness of breath, and sweating are just a few symptoms that may indicate a heart attack. Treatment of heart disease involves control of heart disease risk factors through lifestyle changes, medications, and/or stenting or bypass surgery. Heart disease can be prevented by controlling heart disease risk factors.

Heart attacks symptoms vary greatly for men and women, from anxiety and fatigue to nausea and sweating. Learn the warning signs of a heart attack and know the symptoms that may require an immediate trip to the hospital.

Heart valve disease occurs when the heart valves do not work the way they should. Symptoms of valve disease include shortness of breath, weakness or dizziness, discomfort in your chest, palpitations, swelling of your ankles, feet or abdomen, and rapid weight gain.

The heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.

High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.

Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.

The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.

If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.

What causes high blood pressure (hypertension)? Know the warning signs and symptoms of high blood pressure. Read about high blood pressure medications, diet, and long term treatments.

High blood pressure (hypertension) means high pressure (tension) in the arteries. Treatment for high blood pressure include lifestyle modifications (alcohol, smoking, coffee, salt, diet, exercise), drugs and medications such as ACE inhibitors, angiotensin receptor blockers, beta blockers, diuretics, calcium channel blockers (CCBs), alpha blockers, clonidine, minoxidil, and Exforge.

Migraine headaches are severe headaches that are sensitive to light, sounds, and smells. Some people who suffer from migraines also have severe head pain. People also have symptoms of nausea and vomiting. Common migraine triggers may include:

• Certain foods
• Dehydration
• Changes in barometric pressure
• Stress
• Other phenomenon

They are diagnosed by a doctor if the headache pattern fits established migraine headache criteria. Over-the-counter (OTC) and prescription medications are sometime used to treat acute migraines. To prevent or reduce the frequency and severity of them doctors recommend supplements and prescription medications, for example:

• Blood pressure drugs
• Anti-seizure drugs
• Antidepressants

Lifestyle modification helps in migraine management. Many people who suffer from migraines get relief from their condition by keeping a headache diary, identifying and avoiding triggers, and taking appropriate medication.

Parathyroidectomy is the removal of one or more of the parathyroid glands to treat hyperparathyroidism. Risks of parathyroidectomy include:

• paralysis of the vocal cords,
• difficulty swallowing thin liquids,
• difficulty breathing,
• and drug reactions.

Possible complications of parathyroidectomy include:

• damage to the recurrent laryngeal nerve,
• bleeding or hematoma,
• problems maintaining calcium levels in the blood,
• need for further and more aggressive surgery,
• need for a limited or total thyroidectomy,
• prolonged pain,
• impaired healing,
• and recurrence of the tumor.
