Symptoms of Coronary Artery Disease

The most common symptom of coronary artery disease is angina, or chest pain. Angina can be described as a discomfort, heaviness, pressure, aching, burning, fullness, squeezing, or painful feeling in your chest. It can be mistaken for indigestion or heartburn. Angina is usually felt in the chest, but may also be felt in the shoulders, arms, neck, throat, jaw, or back.

Other symptoms of coronary artery disease include:

• Shortness of breath
• Palpitations (irregular heart beats, skipped beats, or a "flip-flop" feeling in your chest)
• A faster heartbeat
• Weakness or dizziness
• Nausea
• Sweating

Symptoms of a Heart Attack (Myocardial Infarction or MI)

Symptoms of a heart attack can include:

• Discomfort, pressure, heaviness, or pain in the chest, arm, or below the breastbone
• Discomfort radiating to the back, jaw, throat, or arm
• Fullness, indigestion, or choking feeling (may feel like heartburn)
• Sweating, nausea, vomiting, or dizziness
• Extreme weakness, anxiety, or shortness of breath
• Rapid or irregular heartbeats

During a heart attack, symptoms typically last 30 minutes or longer and are not relieved by rest or oral medications (medications taken by mouth). Initial symptoms can start as a mild discomfort that progresses to significant pain.

Some people have a heart attack without having any symptoms (a "silent" MI). A silent MI can occur among all people, though it occurs more often among diabetics.

If you think you are having a heart attack, DO NOT DELAY. Call for emergency help (dial 911 in most areas). Immediate treatment of a heart attack is very important to lessen the amount of damage to your heart.

Symptoms of Arrhythmias

When symptoms of arrhythmias, or an abnormal heart rhythm, are present, they may include:

• Palpitations (a feeling of skipped heart beats, fluttering or "flip-flops," or feeling that your heart is "running away").
• Pounding in your chest.
• Dizziness or feeling light-headed.
• Fainting.
• Shortness of breath.
• Chest discomfort.
• Weakness or fatigue (feeling very tired).

Symptoms of Atrial Fibrillation

Atrial fibrillation (AF) is a type of arrhythmia. Most people with AF experience one or more of the following symptoms:

• Heart palpitations (a sudden pounding, fluttering, or racing feeling in the heart).
• Lack of energy; tired.
• Dizziness (feeling faint or light-headed).
• Chest discomfort (pain, pressure, or discomfort in the chest).
• Shortness of breath (difficulty breathing during activities of daily living).

Some patients with atrial fibrillation have no symptoms. Sometimes these episodes are briefer.

Signs & Symptoms of Weak Kidneys

By Michaele Curtis, eHow Contributor

The condition called weak kidneys (a euphemism for chronic kidney disease) is the slow, continuous progress of kidney damage. One of the reasons that weak kidneys are such a concern is that they often show little or no symptoms early on. When the symptoms do start to show, it is important to catch them to avoid further kidney damage or even total renal failure.

Signs & Symptoms of Weak Kidneys

1. Hypertension

   • Blood pressure is very important to kidney health. Your kidneys use blood pressure as a tool to filter the impurities from your blood. They also help maintain healthy blood pressure by releasing hormones. Hypertension, or high blood pressure, is a big red flag when it comes to kidney damage. That is because hypertension can both be caused by weak kidneys or lead to weak kidneys in an otherwise healthy person. In many cases, hypertension is the first and only sign of weak kidneys.

   Uremia

   • Uremia is the high concentration of urea in the blood. Urea is a waste produced when proteins are broken down. Normally, your kidneys will remove urea from the blood stream and use it to make urine, excreting it from the body. When your kidneys are weak, they may not be able to filter enough urea out of the blood and the urea begins to build up. Urea is toxic, and excess urea can cause your brain and heart to shut down.

   Fluid Retention

   • Another sign of weak kidneys is fluid retention. Also called edema, fluid retention is the buildup of fluid in abnormal areas of the body, like your extremities. Strong, healthy kidneys remove excess water from the blood and use it to make urine. When the water is not removed, it finds other places to go, like your ankles or your fingers. In some case, weak kidneys can even cause edema in the face.

   Anemia

   • Anemia means there is a low presence of oxygen in your blood. Oxygen is required by every cell in your body for even the most basic functioning abilities. Red blood cells transport oxygen to all parts of your body using the circulation system. Healthy kidneys release hormones that trigger the production of red blood cells. Weak kidneys do not release enough or any of that hormone, causing a low red blood cell count. The resulting anemia can make you feel uncharacteristically weak or tired.

   Hematuria

   • Hematuria is the presence of blood in urine. Weak kidneys have trouble filtering the impurities and excess water from the blood while allowing the proteins and nutrients to remain. If your kidneys are weak, blood can pass through the filtration system, mixing with the urine. In fact, any changes in your urine can be a sign of weak kidneys. That includes dark, cloudy or even particularly smelly urine.
