Coronary artery disease is a condition caused by the blockage or narrowing of arteries that supply blood to the heart due to plaque buildup. This slows blood flow to the heart, increasing the risk of a heart attack. Initial signs of this condition are often subtle and easily overlooked.
Exhaustion
When the heart receives insufficient blood, the body lacks energy, causing ongoing fatigue without obvious reason. Individuals with coronary artery disease often experience rapid exhaustion when climbing stairs or walking. Sometimes, shortness of breath can even occur while resting and trying to regain a normal breathing rhythm. These symptoms are often mistaken for anemia, dehydration, or signs of aging.
Shortness of breath
With the heart unable to pump sufficient oxygenated blood, patients may struggle with breathing during routine activities like walking or lifting light items.
Dizziness and lightheadedness
Reduced blood flow to vital organs during intense concentration can trigger sudden weakness, dizziness, and a sensation of faintness. Some individuals experience dizziness when standing up or after exercise, and even after sitting still.
Indigestion and nausea
Feelings such as acid reflux, nausea, or stomach pain without a clear cause may be related to cardiovascular issues.
Cold sweats
Unexplained sudden sweating, without physical exertion or high heat exposure, may signal bodily stress from diminished blood flow.
Cold, numb extremities and slow-healing wounds
Inadequate blood circulation often manifests as distinct physical signs. Common early symptoms include cold, numb extremities, or wounds that heal slowly. Sometimes one leg, foot, hand, or even a single toe may feel colder, paler, or weaker than the other side. These symptoms are often ignored.
Aches in the arms and back
Heart attack pain isn't always confined to the chest. It can spread to the jaw, left arm, upper back, or between the shoulder blades. Patients may also experience unexplained tooth pain, neck discomfort, or arm aches during physical activity. As the body's nerves interconnect, the brain can misinterpret pain's source.
