&lt;h1&gt;Stable angina (angina pectoris)&lt;/h1&gt;
Stable angina is a medical condition that affects the heart. The
most common causes are atherosclerosis and spasms of the
epicardial artery. Typical symptoms include:
&lt;ul&gt;
  &lt;li&gt;chest discomfort&lt;/li&gt;
  &lt;li&gt;feeling of tightness, heaviness, or pain in the chest&lt;/li&gt;
&lt;/ul&gt;
Both stable angina and a heart attack result in chest pain, but
a heart attack will have chest pain lasting at least
10 minutes at rest, repeated episodes of chest pain at rest
lasting 5 or more minutes, or an accelerating pattern of chest
discomfort (episodes that are more frequent, severe,
longer in duration, and precipitated by minimal exertion).
&lt;br&gt;
Risk factors for stable angina include:
&lt;ul&gt;
  &lt;li&gt;Age&lt;/li&gt;
  &lt;li&gt;Gender&lt;/li&gt;
  &lt;li&gt;Systolic blood pressure&lt;/li&gt;
  &lt;li&gt;Smoking&lt;/li&gt;
  &lt;li&gt;Total cholesterol and/or cholesterol:HDL ratio&lt;/li&gt;
  &lt;li&gt;Coronary artery disease&lt;/li&gt;
&lt;/ul&gt;
The initial treatment for stable angina is usually drug therapy
with aspirin, beta blockers, ACE inhibitors, and/or nitroglycerine.
Future episodes of stable angina can sometimes be prevented by
stopping smoking, weight management, and increased physical activity.
