|---|---|
 ANGINA PECTORIS | CONDITION DUE TO CORONARY HEART DISEASE RESULTING IN CHEST PAIN OR DISCOMFORT WHEN HEART DOESN'T GET AS MUCH BLOOD & OXYGEN AS IT NEEDS. OCCURS IF STRESSED OR DURING HIGH ACTIVITY. |
| CARDIAC ISCHEMIA (EE-SKEE-ME-UH) | LACK OF BLOOD FLOW AND OXYGEN TO HEART MUSCLE |
| BALLOON ANGIOPLASTY | TECHNIQUE THAT OPENS NARROWED ARTERIES BY USING A LONG, THIN TUBE CALLED A CATHETER THAT HAS A SMALL BALLOON ON TIP. THE BALLOON INFLATES AT THE BLOCKAGE SITE IN THE ARTERY TO FLATTEN OR COMPRESS THE PLAQUE AGAINST THE ARTERY WALL. |
| BRADYCARDIA | ABNORMALLY SLOW HEART RATE OF LESS THAN 60 BEATS PER MINUTE. |
| CALCIUM CHANNEL BLOCKERS | PREVENT CALCIUM FROM ENTERING CELLS OF THE HEART AND BLOOD VESSELS RESULTING IN LOWER BLOOD PRESSURE. THEY RELAX & WIDEN BLOOD VESSELS BY AFFECTING THE MUSCLE CELLS IN THE ARTERIAL WALL. |
| CARDIAC ARRHYTHMIAS | CONDITION IN WHICH THERE IS ABNORMAL ELECTRIC ACTIVITY IN THE HEART. THE HEART BEAT MAY BE TOO FAST, TOO SLOW, REGULAR OR IRREGULAR. |
| CARDIAC TAMPONADE | CONDITION IN WHICH FLUID COLLECTS IN THE PERICARDIAL SAC PREVENTING VENTRICLES FROM FULLY EXPANDING THUS THEY CANNOT FILL ENOUGH OR PUMP BLOOD. |
| CARDITIS (CAR-DIE-TIS) | INFLAMMATION OF THE HEART. |
| CONDUCTIN DEFICIT | ABNORMALITLY IN THE ELECTRICAL PATHWAYS THAT AFFECT THE TIMING AND PACING OF CARDIAC CONTRACTIONS. |
| CORONARY ARTERY BYPASS GRAFT (CABG) | OPERATION WHERE BLOOD FLOW IS REROUTED THRU A NEW ARTERY OR VEIN THAT IS GRAFTED AROUND DISEASED SECTIONS OF CORONARY ARTERY TO INCREASE BLOOD FLOW TO HEART MUSCLE TISSUE. |
| CORONARY ARTERY DISEASE (CAD) | CONDITION IN WHICH PLAQUE BUILDS UP INSIDE CORONARY ARTERIES. THESE ARTERIES SUPPLY HEART WITH OXYGEN-RICH BLOOD. PLAQUE NARROWS THE ARTERIES & REDUCES BLOOD FLOW TO HEART, MAKES IT MORE LIKELY THAT BLOOD CLOTS WILL FORM CAUSING BLOCK BLOOD FLOW. |
| CORONARY ISCHEMIA (EE-SKEE-ME-UH) | NOT HAVING ENOUGH BLOOD THROUGH THE CORONARY ARTERIES |
| CORONARY THOMBOSIS | BLOCKAGE DUE TO THE FORMATION OF CLOT (THROMBUS) ON PLAQUE IN A CORONARY ARTERY. |
| ELECTROCARDIOGRAM (ECG/EKG) | A RECORDING OF THE ELECTRICAL ACTIVITIES OF THE HEART OVER TIME. |
| HEART FAILURE | PUMPING ACTION GROWS WEAKER & PERIPHERAL TISSUES SUFFER FROM OXYGEN & NUTRIENT DEPRIVATION. |
| HEART MURMUR | ABNORMAL HEARTBEAT DUE TO DEFECTIVE HEART VALVES THUS LEADING TO REGURGITATION. |
| MITRAL VALVE PROLAPSE | BULDGING OF ONE OR BOTH OF THE BICUSPID LEAFLETS INTO THE LEFT ATRIUM DURING HEART CONTRACTION. |
| MYOCARDIAL INFARCTION (MI) | A.K.A. HEART ATTACK DEATH OF HEART MUSCLE BY BLOCKAGE OF CORONARY ARTERY BY BLOOD CLOT. |
| PERICARDITIS | INFLAMMATION OF THE PERICARDIUM. |
| RHEUMATIC HEART DISEASE (RHD) | DISORDER WHERE HEART VALVES BECOME THICKENED & STIFFEN IN A PARTIALLY CLOSED POSITION AFFECTING HEART EFFICIENCY. CAUSED BY RHEUMATIC FEVER I.E. STREP THROAT. |
| TACHYCARDIA | ABNORMALLY FAST HEART RATE OVER 100 BEATS PER MINUTE. |
| VALVULAR HEART DISEASE (VHD) | OCCURS WHEN THE HEART'S VALVES DO NOT WORK THEY WAY THEY SHOULD. |
