Case Study: A 48 y male patient presented with anterior chest pain for 1 hour. He was sent to ER where acute anterior ST-elevation MI was diagnosed. Emergent cardiac catheterization demonstrated a 30-40% stenosis over left main artery, a 100% occlusion over middle portion of left anterior descending artery, 90% stenosis over middle portion of right coronary artery, and a 50% stenosis in the proximal portion of left circumflex artery. Two DES were implanted uneventful: one on LAD and the other on RCA. Echocardiogram revealed an LVEF 52% with mild hypokinesis over LV anterior wall.
Past history: | Type 2 diabetes for 5 years with metformin 1000 mg/d Hypercholesterolemia under rosuvastatin 10 mg/d Denied history of HT No smoking history |
Family history: | Strong family history of premature CVD (His father died of MI at the age of 58. His grandfather died of MI at the age of 65, and his uncle has TVD.) |
Before discharge: | BMI 25 BP 128/76 mmHg, HR 76/min eGFR 76 ml/min, Na 141 meq/L, K 4.1 meq/L HbA1c 7.1% LDL-C 124 mg/dL, HDL-C 42 mg/dL, triglyceride 210 mg/dL, Lp(a) 105 mg/dL |
Discharge medications: | Aspirin 100 mg QD, ticagrelor 90 mg BD, bisoprolol 5 mg QD, metformin 850 mg BD, dapagliflozin 10 mg QD, rosuvastatin 20 mg QD, ezetimibe 10 mg QD |
3-month follow-up clinic: | No symptom BMI 24 BP 120/72 mmHg, HR 66/min eGFR 72 ml/min, Na 144 meq/L, K 4.2 meq/L HbA1c 6.4 % LDL-C 77 mg/dL, HDL-C 48 mg/dL, triglyceride 198 mg/dL, Lp(a) 108 mg/dL |

Case Study: A 67-year-old male comes to the ER with the complaint of excruciating anterior chest pain for 1-hour. The parameters measured in the ER are as follows:
Vital parameters | Blood pressure: 146/78 mm Hg Heart rate: 92/min Respiratory rate: 16/min |
ECG shows ST elevation over V1-V3, suggesting acute anterior MI, and pathological Q waves over leads II, III and aVF. Toponin I was 15.40 ng/mL. Urgent coronary angiograph shows total occlusion over LAD-M, patent left main, patent left circumflex, and 80% stenosis over RCA-M. Left ventriculogram showing moderate hypokinesis over anterior septal area and mild hypokinesis over inferior wall with an EF of 44%. Primary PCI with 2 DES over LAD-M and RCA-M was performed uneventfully.
Past history | Inferior myocardial infarction 4 years with medical treatment HT for more than 10 years with regular treatment Type 2 diabetes for 8 years Denied smoking Obesity with a BMI of 30.5 |
Lab data | Na 134 meq/L, K 4.2 meq/L Cr 1.05 mg/dL, eGFR 73 mL/min (CKD-EPI), UACR 350 mg/g ALT 32 mg/dL HbA1c 8.3% LDL-C 98 mg/dL, HDL-C 28 mg/dL, triglyceride 259 mg/dL Toponin I 15.40 ng/mL, hs-CRP 18.2 mg/dL Lp(a) 83 mg/dL [upper limit of normal Lp(a) = 30 mg/dL] |
Medication history
before admission | Amlodipine 5 mg OD, valsartan 160 mg OD, bisoprolol 5 mg OD Metformin 850 mg BD Aspirin 81 mg OD Atorvastatin 20 mg OD |
Investigation | Acute MI after successful PCI, and this is a second MI (previous inferior MI) Post-MI LV dysfunction (LVEF of 44%) Uncontrolled diabetes (HbA1c 8.3%) Suboptimal control of lipid levels (LDL-C 98 mg/dL) A very high level of Lp(a) (83 mg/dL) |

Case Study: A 63-year-old male presents with central chest and vague left shoulder pain precipitated by a brisk walk up a steep hill. His pain resolved with rest. He is known to have three vessel coronary artery disease based on two previous cardiac catheterizations. He does more than 40 minutes of cardiovascular exercise at least four days a week, has no history of tobacco or drug use, and does not have diabetes.
Vital Parameters | Blood pressure: 110/65 mm Hg Resting heart rate: 65 Body mass index (BMI): 24 |
Medications | 40 mg of Atorvastatin, daily 81 mg of aspirin, daily |
Investigations | Lipid Profile: High-density lipoprotein (HDL) = 65 mg/dl Low-density lipoprotein (LDL) = 50 mg/dl |
The repeat cardiac catheterization reveals greater than 95% occlusion of his left main coronary, left circumflex, left anterior descending, and posterior descending arteries; and right main coronary artery has approximately 50% stenosis. Based on the diagnosis (high risk of CVD/CHD), he was treated with four-vessel coronary artery bypass grafting surgery, after which he returned to his functional baseline of vigorous exercise without angina. However, as The European Atherosclerosis Society consensus panel recommends, screening for anyone at an intermediate or high risk of CVD/CHD with an Lp(a) goal level of < 50 mg/dl, the cardiologist recommended measurement of Lp(a) which revealed an elevated Lp(a) level of 230 nmol/L, which is in the highest quartile.
