Type H hypertension should be H-type hypertension, which is high blood pressure and elevated homocysteine in the same blood. Levamlodipine can be used, and folic acid supplementation is also necessary. Elevated homocysteine levels are due to insufficient folic acid in the patient’s body, or defects in key enzymes in the folic acid metabolism process or mutations in genes, thus causing an increase in homocysteine, which also increases the risk of cardiovascular and cerebrovascular complications. Oral folic acid supplementation is therefore required in the presence of elevated homocysteine. Levamlodipine lowers blood pressure and is an antagonist of the dihydropyridine calcium channel, which acts on peripheral arterial vascular smooth muscle, i.e., it inhibits coronary and small artery constriction induced by adrenaline, 5-hydroxytryptophan, and thromboxane A2 to lower peripheral resistance, but does not have the ability to lower cysteine levels. Adverse reactions such as headache, edema, and nausea may occur with the use of this product. Dosage should be noted in elderly patients and used with caution in patients with hepatic dysfunction. Levamlodipine is contraindicated in patients with hypersensitivity to dihydropyridine calcium antagonists, severe hypotension, and aortic stenosis. Patients are advised to eat more vitamin-rich food and monitor blood pressure. The above drugs should be used under the guidance of doctors in regular hospitals to avoid adverse consequences.
