Elderly patients are a special category of patients, due to the physiological changes induced by age, the great number of comorbidities and drug treatment and last, but not least, to the cognitive dysfunction frequently encountered in this population. Cardiovascular disease is the most important cause of morbidity and mortality in elderly individuals worldwide. The rate of cardiovascular events increases after 65 years in men and after 75 years in women. Myocardial infarction and stroke are the leading disorders caused by atherosclerosis, that lead to death or functional incapacity. Elderly people have a greater risk to develop atherosclerotic cardiovascular disease. The incidence and prevalence of atherosclerosis increase with age and the number of cardiovascular events is higher in elderly patients. The most efficient treatment against atherosclerosis is the treatment with statins, that has been shown to decrease the risk both of stroke and coronary artery disease in all age groups. The advantages of the treatment become evident after at least one year of treatment. Primary prevention is the most important way of preventing cardiovascular disease in elderly individuals, by promoting a healthy lifestyle and reducing the risk factors. Secondary prevention after a stroke or myocardial infarction includes mandatory a statin, to diminish the risk of a recurrent cardiovascular event. The possible side effects of statin therapy are diabetes mellitus, myopathy, and rhabdomyolysis, hepatotoxicity. The side effects of the treatment are more likely to occur in elderly patients, due to their multiple associated comorbidities and drugs that may interact with statins. In elderly people, the benefits and disadvantages of the treatment with statins should be put in balance, especially in those receiving high doses of statins.
Background: Heart failure (HF) and atrial fibrillation (AF) are prevalent cardiovascular diseases, and their association is common. Diastolic dysfunction may be present in patients with AF and all types of HF, leading to elevated intracardiac pressures. The objective of this study was to analyze diastolic dysfunction in patients with HF and AF depending on left ventricle ejection fraction (LVEF). Material and methods: This prospective study included 324 patients with chronic HF and AF (paroxysmal, persistent, or permanent) hospitalized between January 2018 and March 2021. The inclusion criteria were age older than 18 years, diagnosis of chronic HF and AF, and available echocardiographic data. The exclusion criteria were a suboptimal echocardiographic view, other cardiac rhythms than AF, congenital heart disease, or coronavirus 2 infection. Patients were divided into three subgroups according to LVEF: subgroup 1 included 203 patients with HF with reduced ejection fraction (HFrEF) and AF (62.65%), subgroup 2 included 42 patients with HF with mildly reduced ejection fraction (HFmrEF) and AF (12.96%), and subgroup 3 included 79 patients with HF with preserved ejection fraction (HFpEF) and AF (24.38%). We performed 2D transthoracic echocardiography in all patients. Statistical analysis was performed using R software. Results: The E/e′ ratio (p = 0.0352, OR 1.9) and left atrial volume index (56.4 mL/m2 vs. 53.6 mL/m2) were higher in patients with HFrEF than in those with HFpEF. Conclusions: Patients with HFrEF and AF had more severe diastolic dysfunction and higher left ventricular filling pressures than those with HFpEF and AF.
We present the case of a 74 y.o. woman with multiple cardiovascular risk factors, admitted for worsening angina over the past three weeks. On admission she had no significant electrocardiographic and echocardiographic changes and a negative Troponin test. Coronary angiography revealed single vessel disease: severe stenosis of the right coronary artery (RCA) ostium (difficult to assess visually), 50% mid-vessel and 60% distal segment. The left anterior descending artery and circumflex artery had non-significant stenoses. Fractional flow reserve technique (FFR) was used to evaluate the RCA ostial lesion which proved to be significant, therefore angioplasty with three drug-eluting stents was performed for all three lesions of the right coronary artery, starting from the ostium. Due to its location, minimal aortic protrusion of the first stent occluded a small ostial branch which proved to be the conus artery and the patient developed mild transient angina during the procedure, but with good outcome regarding the intracoronary flow. After the angioplasty the patient presented anterior leads ST-elevation and developed mild chest pain with an increase in cardiac enzymes (CK-MB peak 39 U/L). Later on, she had two episodes of ventricular fibrillation with rapid defibrillation to sinus rhythm, with no further events or echocardiographic changes and no recurrent angina. The patient was started on amiodarone to prevent ventricular arrhythmias and continued double antiplatelet therapy with aspirin and clopidogrel. She was discharged six days later. In conclusion, although the conus branch is a small artery, its acute occlusion can have significant life-threatening complications.
